Buda-Lund hydro model and the elliptic flow at RHIC  

E-Print Network (OSTI)

The ellipsoidally symmetric Buda-Lund hydrodynamic model describes naturally the transverse momentum and the pseudorapidity dependence of the elliptic flow in Au+Au collisions at $\\sqrt{s_{NN}} = 130$ and 200 GeV. The result confirms the indication of quark deconfinement in Au+Au collisions at RHIC, obtained from Buda-Lund hydro model fits to combined spectra and HBT radii of BRAHMS, PHOBOS, PHENIX and STAR.

Buda-Lund hydro model for ellipsoidally symmetric fireballs and the elliptic flow at RHIC  

E-Print Network (OSTI)

The ellipsoidally symmetric extension of Buda-Lund hydrodynamic model is shown here to yield a natural description of the pseudorapidity dependence of the elliptic flow $v_2(\\eta)$, as determined recently by the PHOBOS experiment for Au+Au collisions at $\\sqrt{s_{NN}} = 130$ and 200 GeV. With the same set of parameters, the Buda-Lund model describes also the transverse momentum dependence of $v_2$ of identified particles at mid-rapidity. The results confirm the indication for quark deconfinement in Au+Au collisions at RHIC, obtained from a successful Buda-Lund hydro model fit to the single particle spectra and two-particle correlation data, as measured by the BRAHMS, PHOBOS, PHENIX and STAR collaborations.

Oscillating HBT radii and the time evolution of the source - sqrt(s_NN) = 200 GeV Au+Au data analyzed with azimuthally sensitive Buda-Lund hydro model  

E-Print Network (OSTI)

Identified particle spectra of pions, kaons and (anti)protons, and elliptic flow and azimuthal dependence of Bose-Einstein or HBT correlations of identified pions in sqrt(s_NN) = 200 GeV Au+Au collisions is analyzed simultaneously using an ellipsoidally symmetric generalization of the Buda-Lund hydrodynamical model. The transverse flow is found to be faster in the reaction plane than out of plane, which results in a reaction zone that gets slightly more elongated in-plane than out of plane.

Barred Owl Hooting  

NLE Websites -- All DOE Office Websites (Extended Search)

Barred Owl Hooting Barred Owl Hooting Name: ray Location: N/A Country: N/A Date: N/A Question: have barred owls ever been known to hoot during the daylight hours? Replies: I spent two years researching barred and horned owls when I was a graduate student and these owls are often found to call during daylight hours. I found both species fairly active at about 3pm and sometimes as late as 10am. The fledglings may be active anytime day and night. Parents are most vocal in the spring when trying to locate young and in the pre-nesting season during January-March. However, the barred owl is most active during the night and many times the calling is dependent upon the time of year [breeding season of November through April is more active for adults in particular]. Yearlings can make calls, noise anytime during the day.

Nucleon pole contributions in $J/?\\to N \\bar{N} ?$, $p \\bar{p} ?$, $p \\bar{p} ?^{\\prime}$ and $p \\bar{p} ?$ decays  

E-Print Network (OSTI)

Nucleon pole contributions in $J/\\psi \\to N \\bar N \\pi$, $p \\bar p \\eta$, $p \\bar p \\eta^{\\prime}$ and $p \\bar{p} \\omega$ decays are re-studied. Different contributions due to PS-PS and PS-PV couplings in the $\\pi$-N interaction and the effects of $NN\\pi$ form factors are investigated in the $J/\\psi \\to N \\bar N \\pi$ decay channel. It is found that when the ratio of $|F_0| /|F_M|$ takes small value, without considering the $NN\\pi$ form factor, the difference between PS-PS and PS-PV couplings are negligible. However, when the $NN\\pi$ form factor is included, this difference is greatly enlarged. The resultant decay widths are sensitive to the form factors. As a conclusion, the nucleon-pole contribution as a background is important in the $J/\\psi\\to N\\bar{N}\\pi$ decay and must be accounted. In the $J/\\psi\\to N\\bar{N}\\eta$ and $N\\bar{N}\\eta'$ decays, its contribution is less than 0.1% of the data. In the $J/\\psi\\to N\\bar{N}\\omega$ decay, it provides rather important contribution without considering form factors. But the contribution is suppressed greatly when adding the off-shell form factors. Comparing these results with data would help us to select a proper form factor for such kind of decay.

Cam-controlled boring bar  

DOE Patents (OSTI)

A cam-controlled boring bar system (100) includes a first housing (152) which is rotatable about its longitudinal axis (154), and a second housing in the form of a cam-controlled slide (158) which is also rotatable about the axis (154) as well as being translatable therealong. A tool-holder (180) is mounted within the slide (158) for holding a single point cutting tool. Slide (158) has a rectangular configuration and is disposed within a rectangularly configured portion of the first housing (152). Arcuate cam slots (192) are defined within a side plate (172) of the housing (152), while cam followers (194) are mounted upon the cam slide (158) for cooperative engagement with the cam slots (192). In this manner, as the housing (152) and slide (158) rotate, and as the slide (158) also translates, a through-bore (14) having an hourglass configuration will be formed within a workpiece (16) which may be, for example, a nuclear reactor steam generator tube support plate.

Gas Feedback on Stellar Bar Evolution  

E-Print Network (OSTI)

We analyze evolution of live disk-halo systems in the presence of various gas fractions, f_gas less than 8% in the disk. We addressed the issue of angular momentum (J) transfer from the gas to the bar and its effect on the bar evolution. We find that the weakening of the bar, reported in the literature, is not related to the J-exchange with the gas, but is caused by the vertical buckling instability in the gas-poor disks and by a steep heating of a stellar velocity dispersion by the central mass concentration (CMC) in the gas-rich disks. The gas has a profound effect on the onset of the buckling -- larger f_gas brings it forth due to the more massive CMCs. The former process leads to the well-known formation of the peanut-shaped bulges, while the latter results in the formation of progressively more elliptical bulges, for larger f_gas. The subsequent (secular) evolution of the bar differs -- the gas-poor models exhibit a growing bar while gas-rich models show a declining bar whose vertical swelling is driven by a secular resonance heating. The border line between the gas-poor and -rich models lies at f_gas ~ 3% in our models, but is model-dependent and will be affected by additional processes, like star formation and feedback from stellar evolution. The overall effect of the gas on the evolution of the bar is not in a direct J transfer to the stars, but in the loss of J by the gas and its influx to the center that increases the CMC. The more massive CMC damps the vertical buckling instability and depopulates orbits responsible for the appearance of peanut-shaped bulges. The action of resonant and non-resonant processes in gas-poor and gas-rich disks leads to a converging evolution in the vertical extent of the bar and its stellar dispersion velocities, and to a diverging evolution in the bulge properties.

Spontaneous formation of double bars in dark matter dominated galaxies  

E-Print Network (OSTI)

Although nearly one-third of barred galaxies host an inner, secondary bar, the formation and evolution of double barred galaxies remain unclear. We show here an example model of a galaxy, dominated by a live dark matter halo, in which double bars form naturally, without requiring gas, and we follow its evolution for a Hubble time. The inner bar in our model galaxy rotates almost as slowly as the outer bar, and it can reach up to half of its length. The route to the formation of a double bar may be different from that of a single strong bar. Massive dark matter halo or dynamically hot stellar disc may play an important role in the formation of double bars and their subsequent evolution.

SQA(TM): Surface Quality Assured Steel Bar Program  

SciTech Connect

OG Technologies, Inc. (OGT) has led this SQA (Surface Quality Assured Steel Bar) program to solve the major surface quality problems plaguing the US special quality steel bars and rods industry and their customers, based on crosscutting sensors and controls technologies. Surface defects in steel formed in a hot rolling process are one of the most common quality issues faced by the American steel industry, accounting for roughly 50% of the rejects or 2.5% of the total shipment. Unlike other problems such as the mechanical properties of the steel product, most surface defects are sporadic and cannot be addressed based on sampling techniques. This issue hurts the rolling industry and their customers in their process efficiency and operational costs. The goal of this program is to develop and demonstrate an SQA prototype, with synergy of HotEye and other innovations, that enables effective rolling process control and efficient quality control. HotEye, OGTs invention, delivers high definition images of workpieces at or exceeding 1,450?C while the workpieces travel at 100 m/s. The elimination of surface defect rejects will be achieved through the integration of imaging-based quality assessment, advanced signal processing, predictive process controls and the integration with other quality control tools. The SQA program team, composed of entities capable of and experienced in (1) research, (2) technology manufacturing, (3) technology sales and marketing, and (4) technology end users, is very strong. There were 5 core participants: OGT, Georgia Institute of Technology (GIT), University of Wisconsin (UW), Charter Steel (Charter) and ArcelorMittal Indiana Harbor (Inland). OGT served as the project coordinator. OGT participated in both research and commercialization. GIT and UW provided significant technical inputs to this SQA project. The steel mills provided access to their rolling lines for data collection, design of experiments, host of technology test and verification, and first-hand knowledge of the most advanced rolling line operation in the US. This project lasted 5 years with 5 major tasks. The team successfully worked through the tasks with deliverables in detection, data analysis and process control. Technologies developed in this project were commercialized as soon as they were ready. For instance, the advanced surface defect detection algorithms were integrated into OGTs HotEye RSB systems late 2005, resulting in a more matured product serving the steel industry. In addition to the commercialization results, the SQA team delivered 7 papers and 1 patent. OGT was also recognized by two prestigious awards, including the R&D100 Award in 2006. To date, this SQA project has started to make an impact in the special bar quality industry. The resulted product, HotEye RSB systems have been accepted by quality steel mills worldwide. Over 16 installations were completed, including 1 in Argentina, 2 in Canada, 2 in China, 2 in Germany, 2 in Japan, and 7 in the U.S. Documented savings in reduced internal rejects, improved customer satisfaction and simplified processes were reported from various mills. In one case, the mill reported over 50% reduction in its scrap, reflecting a significant saving in energy and reduction in emission. There exist additional applications in the steel industry where the developed technologies can be used. OGT is working toward bringing the developed technologies to more applications. Examples are: in-line inspection and process control for continuous casting, steel rails, and seamless tube manufacturing.

The BaBar Drift Chamber  

E-Print Network (OSTI)

The central drift chamber for the BaBar detector at the PEP-II B-factory at SLAC is a cylindrical chamber with a length of 280 cm and outer radius of 81 cm. It consists of 40 layers of small hexagonal cells arranged in 10 axial and stereo super-layers. In order to minimize multiple scattering, light materials are used for the mechanical structure, and the gas mixture is Helium based. The pulse-height and timing electronics are mounted directly on the chamber rear end-plate. A full length prototype of the BaBar drift chamber has been built. The analysis of cosmic ray events measures the spatial resolution averaged in the cell to be 130 m and the dE/dx resolution to be 6.8%, meeting the performance goals for the BaBar central tracker. The mechanical assembly and stringing of the chamber was completed in December 1997 and the detector will be integrated into BaBar during summer 1998. 1

Bar-code automated waste tracking system  

Science Conference Proceedings (OSTI)

The Bar-Code Automated Waste Tracking System was designed to be a site-Specific program with a general purpose application for transportability to other facilities. The system is user-friendly, totally automated, and incorporates the use of a drive-up window that is close to the areas dealing in container preparation, delivery, pickup, and disposal. The system features ``stop-and-go`` operation rather than a long, tedious, error-prone manual entry. The system is designed for automation but allows operators to concentrate on proper handling of waste while maintaining manual entry of data as a backup. A large wall plaque filled with bar-code labels is used to input specific details about any movement of waste.

Study of the decay $\\bar{B}^{0}\\rightarrow?_{c}^{+}\\bar{p}?^{+}?^{-}$ and its intermediate states  

E-Print Network (OSTI)

We study the decay $\\bar{B}^{0}\\rightarrow\\Lambda_{c}^{+}\\bar{p}\\pi^{+}\\pi^{-}$, reconstructing the \\Lambda_{c}^{+} baryon in the $p K^{-}\\pi^{+}$ mode, using a data sample of $467\\times 10^{6}$ $B\\bar{B}$ pairs collected with the BaBar detector at the PEP-2 storage rings at SLAC. We measure branching fractions for decays with intermediate $\\Sigma_{c}$ baryons to be ${\\cal B}[\\bar{B}^{0}\\rightarrow\\Sigma_{c}(2455)^{++}\\bar{p}\\pi^{-}]=(21.3 \\pm 1.0 \\pm 1.0 \\pm 5.5) \\times 10^{-5}$, ${\\cal B}[\\bar{B}^{0}\\rightarrow\\Sigma_{c}(2520)^{++}\\bar{p}\\pi^{-}]=(11.5\\pm 1.0 \\pm 0.5 \\pm 3.0)\\times 10^{-5}$, ${\\cal B}[\\bar{B}^{0}\\rightarrow\\Sigma_{c}(2455)^{0}\\bar{p}\\pi^{+}]=(9.1 \\pm 0.7 \\pm 0.4 \\pm 2.4)\\times10^{-5}$, and ${\\cal B}[\\bar{B}^{0}\\rightarrow\\Sigma_{c}(2520)^{0}\\bar{p}\\pi^{+}]= (2.2 \\pm 0.7 \\pm 0.1\\pm 0.6) \\times 10^{-5}$, where the uncertainties are statistical, systematic, and due to the uncertainty on the $\\Lambda_{c}^{+}\\rightarrow\\proton\\Km\\pi^{+}$ branching fraction, respectively. For decays without $\\Sigma_{c}(2455)$ or $\\Sigma_{c}(2520)$ resonances, we measure ${\\cal B}[\\bar{B}^{0}\\rightarrow\\Lambda_{c}^{+}\\bar{p}\\pi^{+}\\pi^{-}]_{\\mathrm{non-\\Sigma_{c}}}=(79 \\pm 4 \\pm 4 \\pm 20)\\times10^{-5}$. The total branching fraction is determined to be ${\\cal B}[\\bar{B}^{0}\\rightarrow\\Lambda_{c}^{+}\\bar{p}\\pi^{+}\\pi^{-}]_{\\mathrm{total}}=(123 \\pm 5 \\pm 7 \\pm 32)\\times10^{-5}$. We examine multibody mass combinations in the resonant three-particle $\\Sigma_{c}\\bar{p}\\pi$ final states and in the four-particle $\\Lambda_{c}^{+}\\bar{p}\\pi^{+}\\pi^{-}$ final state, and observe different characteristics for the $\\bar{p}\\pi$ combination in neutral versus doubly-charged $\\Sigma_{c}$ decays.

Why Buckling Stellar Bars Weaken in Disk Galaxies  

E-Print Network (OSTI)

Young stellar bars in disk galaxies experience a vertical buckling instability which terminates their growth and thickens them, resulting in a characteristic peanut/boxy shape when viewed edge on. Using N-body simulations of galactic disks embedded in live halos, we have analyzed the bar structure throughout this instability and found that the outer third of the bar dissolves completely while the inner part (within the vertical inner Lindblad resonance) becomes less oval. The bar acquires the frequently observed peanut/boxy-shaped isophotes. We also find that the bar buckling is responsible for a mass injection above the plane, which is subsequently trapped by specific 3-D families of periodic orbits of particular shapes explaining the observed isophotes, in line with previous work. Using a 3-D orbit analysis and surfaces of sections, we infer that the outer part of the bar is dissolved by a rapidly widening stochastic region around its corotation radius -- a process related to the bar growth. This leads to a dramatic decrease in the bar size, decrease in the overall bar strength and a mild increase in its pattern speed, but is not expected to lead to a complete bar dissolution. The buckling instability appears primarily responsible for shortening the secular diffusion timescale to a dynamical one when building the boxy isophotes. The sufficiently long timescale of described evolution, ~1 Gyr, can affect the observed bar fraction in local universe and at higher redshifts, both through reduced bar strength and the absence of dust offset lanes in the bar.

Kolkata Restaurant Problem as a generalised El Farol Bar Problem  

E-Print Network (OSTI)

Generalisation of the El Farol bar problem to that of many bars here leads to the Kolkata restaurant problem, where the decision to go to any restaurant or not is much simpler (depending on the previous experience of course, as in the El Farol bar problem). This generalised problem can be exactly analysed in some limiting cases discussed here. The fluctuation in the restaurant service can be shown to have precisely an inverse cubic behavior, as widely seen in the stock market fluctuations.

Bus bar electrical feedthrough for electrorefiner system  

SciTech Connect

A bus bar electrical feedthrough for an electrorefiner system may include a retaining plate, electrical isolator, and/or contact block. The retaining plate may include a central opening. The electrical isolator may include a top portion, a base portion, and a slot extending through the top and base portions. The top portion of the electrical isolator may be configured to extend through the central opening of the retaining plate. The contact block may include an upper section, a lower section, and a ridge separating the upper and lower sections. The upper section of the contact block may be configured to extend through the slot of the electrical isolator and the central opening of the retaining plate. Accordingly, relatively high electrical currents may be transferred into a glovebox or hot-cell facility at a relatively low cost and higher amperage capacity without sacrificing atmosphere integrity.

End to deficit of LPG. [Argentina  

SciTech Connect

In the Buenos Aires province of Argentina, Gas de Estado is constructing the future heart of the petrochemical complex, Bahia Blanca. The complex contains 2 absorption-refrigeration plants, a gas compressing plant, equipment maintenance shops and an important operations base for the Argentine truck gas pipelines. This will be the largest LPG plant in Latin America. The General Cerri plant, under construction, is located in an area of 40,000 sq m with new installations to extract ethane and higher hydrocarbons. The design optimizes the extraction of hydrocarbons from the natural gas and recovers 76% of the ethane. Selection of the process resulted from an investigation that compared the system with processes that use water cooling and absorption with refrigerated oil.

BARS REJUVENATING BULGES? EVIDENCE FROM STELLAR POPULATION ANALYSIS  

SciTech Connect

We obtained stellar ages and metallicities via spectrum fitting for a sample of 575 bulges with spectra available from the Sloan Digital Sky Survey. The structural properties of the galaxies have been studied in detail in 2009 by Gadotti and the sample contains 251 bulges in galaxies with bars. Using the whole sample, where galaxy stellar mass distributions for barred and unbarred galaxies are similar, we find that bulges in barred and unbarred galaxies occupy similar loci in the age versus metallicity plane. However, the distribution of bulge ages in barred galaxies shows an excess of populations younger than {approx}4 Gyr, when compared to bulges in unbarred galaxies. Kolmogorov-Smirnov statistics confirm that the age distributions are different with a significance of 99.94%. If we select sub-samples for which the bulge stellar mass distributions are similar for barred and unbarred galaxies, this excess vanishes for galaxies with bulge mass log M < 10.1 M{sub Sun }, while for more massive galaxies we find a bimodal bulge age distribution for barred galaxies only, corresponding to two normal distributions with mean ages of 10.4 and 4.7 Gyr. We also find twice as much active galactic nuclei among barred galaxies, as compared to unbarred galaxies, for low-mass bulges. By combining a large sample of high-quality data with sophisticated image and spectral analysis, we are able to find evidence that the presence of bars affects the mean stellar ages of bulges. This lends strong support to models in which bars trigger star formation activity in the centers of galaxies.

Production of htt_bar and htT_bar in littlest Higgs model with T-parity  

E-Print Network (OSTI)

In the littlest Higgs model with T-parity, which predicts a pair of T-even and T-odd partners for the top quark, the top quark interactions are altered with respect to the Standard Model predictions and deviation will manifest in various top quark processes. In this work we examine the effects in htt_bar productions at the ILC and LHC. We find that in the allowed parameter space, the cross sections can be significantly deviated from the Standard Model predictions and thus provide a good test for the littlest Higgs model with T-parity. We also examine the new production channel, the htT_bar or hTt_bar production, at the LHC, which give the same final states as htt_bar production due to the dominant decay T->Wb. We find that, compared with htt_bar production, this new production channel can have a sizable production rate for a T-quark below TeV scale. Such a production will be counted into htt_bar events or possibly extracted from htt_bar events, depending on if we can distinguish the T-quark from the top quark from mass reconstructions.

Study of $J/\\psi\\to p\\bar{p}$ and $J/\\psi\\to n\\bar{n}$  

E-Print Network (OSTI)

The decays $J/\\psi\\to p\\bar{p}$ and $J/\\psi\\to n\\bar{n}$ have been investigated with a sample of 225.2 million $J/\\psi$ events collected with the BESIII detector at the BEPCII $e^+e^-$ collider. The branching fractions are determined to be $\\mathcal{B}(J/\\psi\\to p\\bar{p})=(2.112\\pm0.004\\pm0.031)\\times10^{-3}$ and $\\mathcal{B}(J/\\psi\\to n\\bar{n})=(2.07\\pm0.01\\pm0.17)\\times10^{-3}$. Distributions of the angle $\\theta$ between the proton or anti-neutron and the beam direction are well described by the form $1+\\alpha\\cos^2\\theta$, and we find $\\alpha=0.595\\pm0.012\\pm0.015$ for $J/\\psi\\to p\\bar{p}$ and $\\alpha=0.50\\pm0.04\\pm0.21$ for $J/\\psi\\to n\\bar{n}$.

A quark model of {bar {Lambda}}{Lambda} production in {bar p}p interactions  

SciTech Connect

A quark model which includes both scalar and vector contributions to the reaction mechanism (SV quark model) is used in a DWBA calculation of {anti {Lambda}}{Lambda} production in {bar p}p interactions. Total and differential cross-sections, polarizations, depolarizations, and spin-correlation coefficients are computed for laboratory momenta from threshold to 1695 MeV/c. The free parameters of the calculation are the scalar and vector strengths, a quark cluster size parameter, and the parameters of the unknown {anti {Lambda}}{Lambda} potentials. Good agreement with experiment is found for constructive interference of the scalar and vector terms, and for {anti {Lambda}}{Lambda} potentials which differ from those suggested by several authors on the basis of SU(3) arguments. The fit to the data is better than that obtained by other quark models, which use only scalar or vector annihilation terms. The agreement with experiment is also better than that found in meson-exchange models. The recent suggestion [1] that measurement of the depolarization parameter D{sub nn} can be used to discriminate between meson-exchange and quark models is examined in detail. We conclude that a measurement of D{sub nn} will provide a test of which of these models, as presently constructed, is the more appropriate description of strangeness production in the {bar p}p {yields} {anti {Lambda}}{Lambda} reaction.

The distribution of stellar population age in galactic bars  

E-Print Network (OSTI)

Recent analysis of stellar populations in barred galaxies have focused on the spatial distribution of stellar population ages and metallicities. However, barred galaxies are complex objects where dynamical instabilities play a leading role in shaping any spatial distribution. The age distribution of stellar populations should thus be analyzed from the two points of view of stellar population evolution and dynamical secular evolution. Chemodynamical simulations of single barred galaxies with simple but realistic star formation and feedback recipes are used to produce face-on mass-weighted maps of stellar population ages. Luminosity-weighted maps in V-band are also displayed after calibrating the simulation with mass-to-light ratios provided by a synthesis population model. It is shown that inside a stellar bar two persistent diametrically opposed regions display a mean age lower than the surrounding average. These two low-age regions are due to the accumulation of young stellar populations trapped on elliptica...

The Fueling of Nuclear Activity: II. The Bar Properties of Seyfert and Normal Galaxies  

E-Print Network (OSTI)

We use a recent near-infrared imaging survey of samples of Seyfert and normal galaxies to study the role of bars in the fueling of nuclear activity. The active galaxy sample includes Seyfert galaxies in the Revised Shapely-Ames (RSA) and Sandage & Tammann's (1987) extension to this catalog. The normal galaxies were selected to match the Seyfert sample in Hubble type, redshift, inclination and blue luminosity. All the galaxies in both samples classified as barred in the RSA catalog are also barred in the near-infrared. In addition, ~55% of the galaxies classified as non-barred in the RSA show evidence for bars at 2.1 microns. Overall, ~70% of the galaxies observed show evidence for bar structures. The incidence of bars in the Seyfert and normal galaxies is similar, suggesting Seyfert nuclei do not occur preferentially in barred systems. Furthermore, a slightly higher percentage of normal galaxies have multiple-bar structures.

Antihydrogen $(\\bar{\\rm{H}})$ and muonic antihydrogen $(\\bar{\\rm{H}}_{\\mu})$ formation in low energy three-charge-particle collisions  

E-Print Network (OSTI)

A few-body formalism is applied for computation of two different three-charge-particle systems. The first system is a collision of a slow antiproton, $\\bar{\\rm{p}}$, with a positronium atom: Ps$=(e^+e^-)$ $-$ a bound state of an electron and a positron. The second problem is a collision of $\\bar{\\rm{p}}$ with a muonic muonium atom, i.e. true muonium $-$ a bound state of two muons one positive and one negative: Ps$_{\\mu}=(\\mu^+\\mu^-)$. The total cross section of the following two reactions: $\\bar{\\rm p}+(e^+e^-) \\rightarrow \\bar{\\rm{H}} + e^-$ and $\\bar{\\rm p}+(\\mu^+\\mu^-) \\rightarrow \\bar{\\rm{H}}_{\\mu} + \\mu^-$, where $\\bar{\\rm{H}}=(\\bar{\\rm p}e^+)$ is antihydrogen and $\\bar{\\rm{H}}_{\\mu}=(\\bar{\\rm p}\\mu^+)$ is a muonic antihydrogen atom, i.e. a bound state of $\\bar{\\rm{p}}$ and $\\mu^+$, are computed in the framework of a set of coupled two-component Faddeev-Hahn-type (FH-type) equations.

We analyze the problem of how to determine the parity of the $\\Theta^+$ pentaquark in the reaction $\\gamma N\\to K\\Theta\\to NK\\bar{K}$, where $N=n,p$. Our model calculations indicate that the contribution of the non-resonant background of the reaction $\\gamma N\\to NK\\bar{K}$ cannot be neglected, and that suggestions to determine the parity based solely on the initial-stage process $\\gamma N\\to K\\Theta$ cannot be implemented cleanly. We discuss the various mechanisms that contribute to the background, and we identify some spin observables which are sensitive.

TWO-DIMENSIONAL MAGNETOHYDRODYNAMIC SIMULATIONS OF BARRED GALAXIES  

Science Conference Proceedings (OSTI)

Barred galaxies are known to possess magnetic fields that may affect the properties of bar substructures such as dust lanes and nuclear rings. We use two-dimensional high-resolution magnetohydrodynamic (MHD) simulations to investigate the effects of magnetic fields on the formation and evolution of such substructures, as well as on the mass inflow rates to the galaxy center. The gaseous medium is assumed to be infinitesimally thin, isothermal, non-self-gravitating, and threaded by initially uniform, azimuthal magnetic fields. We find that there exists an outermost x{sub 1}-orbit relative to which gaseous responses to an imposed stellar bar potential are completely different between inside and outside. Inside this orbit, gas is shocked into dust lanes and infalls to form a nuclear ring. Magnetic fields are compressed in dust lanes, reducing their peak density. Magnetic stress removes further angular momentum of the gas at the shocks, temporarily causing the dust lanes to bend into an 'L' shape and eventually leading to a smaller and more centrally distributed ring than in unmagnetized models. The mass inflow rates in magnetized models correspondingly become larger, by more than two orders of magnitude when the initial fields have an equipartition value with thermal energy, than in the unmagnetized counterparts. Outside the outermost x{sub 1}-orbit, on the other hand, an MHD dynamo due to the combined action of the bar potential and background shear operates near the corotation and bar-end regions, efficiently amplifying magnetic fields. The amplified fields shape into trailing magnetic arms with strong fields and low density. The base of the magnetic arms has a thin layer in which magnetic fields with opposite polarity reconnect via a tearing-mode instability. This produces numerous magnetic islands with large density that propagate along the arms to turn the outer disk into a highly chaotic state.

Analysis of B ? ?l? Decays With BaBar  

SciTech Connect

As part of the BaBar project at SLAC to study the properties of B mesons, we have carried out a study of the exclusive charmless semileptonic decay mode B ? ?l?, which can be used to determine the magnitude of the Cabbibo- Kobayashi-Maskawa matrix element Vub. Using simulated event samples, this study focuses on determining criteria on variables for selection of B ? ?l? signal and suppression of background from other types of BB events and continuum processes. In addition, we determine optimal cuts on variables to ensure a good neutrino reconstruction. With these selection cuts, we were able to achieve a signal-to-background ratio of 0.68 and a signal efficiency of the order of 1%. Applying these cuts to a sample of 83 million BB events recorded by BaBar in e+e collisions at the (4S) resonance, we obtain a yield of 115 19 B ? ?l? decays.

Nuclear rapprochement in Argentina and Brazil: Workshop summary  

Science Conference Proceedings (OSTI)

On October 21 and 22, 1998, the Center for International Security Affairs at Los Alamos National Laboratory and the Center for Global Security and Cooperation at Science Applications International Corporation hosted the first of a series of work-shops on states that have chosen to roll back their pursuit of nuclear arms. The objective of the workshop series is to conduct a systematic evaluation of the roles played by U.S. nonproliferation policy in cases of nuclear rollback or restraint and to provide recommendations for future nonproliferation efforts based on lessons learned. Key attendees at the workshop included officials and former officials from the foreign ministries of Argentina and Brazil, and current and former officials from the U.S. Department of State, the Arms Control and Disarmament Agency (ACDA), and the Department of Energy (DOE). Scholars and independent researchers who have examined nuclear policy in Argentina and Brazil also participated. This workshop report includes important background information that helps set the stage for assessing nuclear policies in Argentina and Brazil. It describes national perspectives and areas of consensus and debate among the participants, particularly on the questions of lessons learned and their salience to proliferation challenges in other states. It also summarizes key questions and propositions regarding the roles played in these cases by U.S. nonproliferation policy.

Energy dependence of $\\bar{K}N$ interaction in nuclear medium  

E-Print Network (OSTI)

When the $\\bar{K}N$ system is submerged in nuclear medium the $\\bar{K}N$ scattering amplitude and the final state branching ratios exhibit a strong energy dependence when going to energies below the $\\bar{K}N$ threshold. A sharp increase of $\\bar{K}N$ attraction below the $\\bar{K}N$ threshold provides a link between shallow $\\bar{K}$-nuclear potentials based on the chiral $\\bar{K}N$ amplitude evaluated at threshold and the deep phenomenological optical potentials obtained in fits to kaonic atoms data. We show the energy dependence of the in-medium $K^{-}p$ amplitude and demonstrate the impact of energy dependent branching ratios on the $\\Lambda$-hypernuclear production rates. \\keywords{kaon-nucleon amplitude \\and nuclear medium \\and hypernuclei

Dynamic tensile characterization of a 4330 steel with kolsky bar techniques.  

Science Conference Proceedings (OSTI)

There has been increasing demand to understand the stress-strain response as well as damage and failure mechanisms of materials under impact loading condition. Dynamic tensile characterization has been an efficient approach to acquire satisfactory information of mechanical properties including damage and failure of the materials under investigation. However, in order to obtain valid experimental data, reliable tensile experimental techniques at high strain rates are required. This includes not only precise experimental apparatus but also reliable experimental procedures and comprehensive data interpretation. Kolsky bar, originally developed by Kolsky in 1949 [1] for high-rate compressive characterization of materials, has been extended for dynamic tensile testing since 1960 [2]. In comparison to Kolsky compression bar, the experimental design of Kolsky tension bar has been much more diversified, particularly in producing high speed tensile pulses in the bars. Moreover, instead of directly sandwiching the cylindrical specimen between the bars in Kolsky bar compression bar experiments, the specimen must be firmly attached to the bar ends in Kolsky tensile bar experiments. A common method is to thread a dumbbell specimen into the ends of the incident and transmission bars. The relatively complicated striking and specimen gripping systems in Kolsky tension bar techniques often lead to disturbance in stress wave propagation in the bars, requiring appropriate interpretation of experimental data. In this study, we employed a modified Kolsky tension bar, newly developed at Sandia National Laboratories, Livermore, CA, to explore the dynamic tensile response of a 4330-V steel. The design of the new Kolsky tension bar has been presented at 2010 SEM Annual Conference [3]. Figures 1 and 2 show the actual photograph and schematic of the Kolsky tension bar, respectively. As shown in Fig. 2, the gun barrel is directly connected to the incident bar with a coupler. The cylindrical striker set inside the gun barrel is launched to impact on the end cap that is threaded into the open end of the gun barrel, producing a tension on the gun barrel and the incident bar.

Thermal and environmental effects on fiber-reinforced polymer reinforcing bars and reinforced concrete elements  

E-Print Network (OSTI)

Corrosion of steel reinforcement in bridge decks results in high repair costs, unwanted traffic disruption, and unsafe structures. To help alleviate this problem, non-metallic fiber-reinforced polymer (FRP) bars are being studied as an alternate type of reinforcement in bridge decks. In order to determine the suitability of the use of FRP bars, a number of tests have been performed on FRP bars to evaluate their long-term performance. These tests include uniaxial tension tests under a variety of environmental conditions and thermal expansion of the bars embedded in concrete. In an effort to characterize the FRP bars and to gain insight into their long-term performance, batteries of tests have been carried out. Samples from three different manufacturers were exposed under different environmental conditions and tested in uniaxial tension. For one of the bar types, the strength increased, while the other two bar types lost strength. In all cases, the modulus of the bars increased with exposure time. In addition, FRP reinforced concrete specimens were evaluated for thermal expansion. The results indicate that thermal cracking of the concrete by FRP bar expansion is not a significant problem.

ORNL Trusted Corridors Project: Watts Bar Dam Inland Waterway Project  

Science Conference Proceedings (OSTI)

Radiation has existed everywhere in the environment since the Earth's formation - in rocks, soil, water, and plants. The mining and processing of naturally occurring radioactive materials for use in medicine, power generation, consumer products, and industry inevitably generate emissions and waste. Radiological measuring devices have been used by industry for years to measure for radiation in undesired locations or simply identify radioactive materials. Since the terrorist attacks on the United States on 9-11-01 these radiation measuring devices have proliferated in many places in our nation's commerce system. DOE, TVA, the Army Corps and ORNL collaborated to test the usefulness of these devices in our nation's waterway system on this project. The purpose of the Watts Bar Dam ORNL Trusted Corridors project was to investigate the security, safety and enforcement needs of local, state and federal government entities for state-of-the-art sensor monitoring in regards to illegal cargo including utilization of the existing infrastructure. TVA's inland waterways lock system is a recognized and accepted infrastructure by the commercial carrier industry. Safety Monitoring activities included tow boat operators, commercial barges and vessels, recreational watercraft and their cargo, identification of unsafe vessels and carriers, and, monitoring of domestic and foreign commercial vessels and cargo identification. Safety Enforcement activities included cargo safety, tracking, identification of hazardous materials, waterway safety regulations, and hazardous materials regulations. Homeland Security and Law Enforcement Applications included Radiological Dispersive Devices (RDD) identification, identification of unsafe or illicit transport of hazardous materials including chemicals and radiological materials, and screening for shipments of illicit drugs. In the Fall of 2005 the SensorNet funding for the project expired. After several unsuccessful attempts to find a Federal sponsor to continue with the project, the Watts Bar Dam Project was canceled and the Exploranium radiation monitors were removed from the doors of Watts Bar Dam in early 2006. The DHS Domestic Nuclear Detection Office decided to proceed with a Pilot building on the ORNL work performed at the TN and SC weigh stations in the highway sector of the Trusted Corridors project and eventually expanded it to other southern states under the name of Southeastern Corridor Pilot Project (SETCP). Many of the Phase I goals were achieved however real-world test data of private watercraft and barges was never obtained.

A preliminary measurement of the branching fraction {Beta}({tau}{sup -} {yields} K{sub S}{sup 0}{pi}{sup -}{nu}{sub {tau}}) is made using 384.6 fb{sup -1} of e{sup +}e{sup -} collision data provided by the PEP-II collider, operating primarily at {radical}s = 10.58 GeV, and recorded using the BABAR detector. From this they measure: {Beta}({tau}{sup -} {yields} {bar K}{sup 0}{pi}{sup -}{nu}{sub {tau}}) = (0.840 {+-} 0.004(stat) {+-} 0.023(syst))%. This result is the most precise measurement to date and is consistent with the world average.

X-ray nuclear activity in S4G barred galaxies: No link between bar strength and co-occurrent supermassive black hole fueling  

E-Print Network (OSTI)

Stellar bars can lead to gas inflow toward the center of a galaxy and stimulate nuclear star formation. However, there is no compelling evidence on whether they also feed a central supermassive black hole: by measuring the fractions of barred active and inactive galaxies, previous studies have yielded conflicting results. In this paper, we aim to understand the lack of observational evidence for bar-driven active galactic nucleus (AGN) activity by studying a sample of 41 nearby (d nuclear 2--10 keV X-ray luminosities and estimate Eddington ratios, together with Spitzer 3.6um imaging to quantify the strength of the stellar bar in two independent ways: (1) from its structure, as traced by its ellipticity and boxiness, and (2) from its gravitational torque Q_b, taken as the maximum ratio of the tangential force to the mean background radial force. In this way, rather than discretizing th...

Using Hubble Space Telescope Imaging of Nuclear Dust Morphology to Rule Out Bars Fueling Seyfert Nuclei  

E-Print Network (OSTI)

If AGN are powered by the accretion of matter onto massive black holes, how does the gas in the host galaxy lose the required angular momentum to approach the black hole? Gas easily transfers angular momentum to stars in strong bars, making them likely candidates. Although ground-based searches for bars in active galaxies using both optical and near infrared surface brightness have not found any excess of bars relative to quiescent galaxies, the searches have not been able to rule out small-scale nuclear bars. To look for these nuclear bars we use HST WFPC2-NICMOS color maps to search for the straight dust lane signature of strong bars. Of the twelve Seyfert galaxies in our sample, only three have dust lanes consistent with a strong nuclear bar. Therefore, strong nuclear bars cannot be the primary fueling mechanism for Seyfert nuclei. We do find that a majority of the galaxies show an spiral morphology in their dust lanes. These spiral arms may be a possible fueling mechanism.

Evidence for Spin Correlation in t(t)over-bar Production  

SciTech Connect

We present a measurement of the ratio of events with correlated t and {bar t} spins to the total number of t{bar t} events. This ratio f is evaluated using a matrix-element-based approach in 729 t{bar t} candidate events with a single lepton {ell} (electron or muon) and at least four jets. The analyzed p{bar p} collisions data correspond to an integrated luminosity of 5.3 fb{sup -1} and were collected with the D0 detector at the Fermilab Tevatron collider operating at a center-of-mass energy {radical}s = 1.96 TeV. Combining this result with a recent measurement of f in dileptonic final states, we find f in agreement with the standard model. In addition, the combination provides evidence for the presence of spin correlation in t{bar t} events with a significance of more than 3 standard deviations.

Nonlinear Development of the Secular Bar-mode Instability in Rotating Neutron Stars  

E-Print Network (OSTI)

We have modelled the nonlinear development of the secular bar-mode instability that is driven by gravitational radiation-reaction (GRR) forces in rotating neutron stars. In the absence of any competing viscous effects, an initially uniformly rotating, axisymmetric $n=1/2$ polytropic star with a ratio of rotational to gravitational potential energy $T/|W| = 0.181$ is driven by GRR forces to a bar-like structure, as predicted by linear theory. The pattern frequency of the bar slows to nearly zero, that is, the bar becomes almost stationary as viewed from an inertial frame of reference as GRR removes energy and angular momentum from the star. In this ``Dedekind-like'' state, rotational energy is stored as motion of the fluid in highly noncircular orbits inside the bar. However, in less than 10 dynamical times after its formation, the bar loses its initially coherent structure as the ordered flow inside the bar is disrupted by what appears to be a purely hydrodynamical, short-wavelength, ``shearing'' type instability. The gravitational waveforms generated by such an event are determined, and an estimate of the detectability of these waves is presented.

The Bar-Halo Interaction - II. Secular evolution and the religion of N-body simulations  

E-Print Network (OSTI)

This paper explores resonance-driven secular evolution between a bar and dark-matter halo using N-body simulations. We make direct comparisons to our analytic theory (Weinberg & Katz 2005) to demonstrate the great difficulty that an N-body simulation has representing these dynamics for realistic astronomical interactions. In a dark-matter halo, the bar's angular momentum is coupled to the central density cusp (if present) by the Inner Lindblad Resonance. Owing to this angular momentum transfer and self-consistent re-equilibration, strong realistic bars WILL modify the cusp profile, lowering the central densities within about 30% of the bar radius in a few bar orbits. Past results to the contrary (Sellwood 2006, McMillan & Dehnen 2005) may be the result of weak bars or numerical artifacts. The magnitude depends on many factors and we illustrate the sensitivity of the response to the dark-matter profile, the bar shape and mass, and the galaxy's evolutionary history. For example, if the bar length is comparable to the size of a central dark-matter core, the bar may exchange angular momentum without changing its pattern speed significantly. We emphasise that this apparently simple example of secular evolution is remarkably subtle in detail and conclude that an N-body exploration of any astronomical scenario requires a deep investigation into the underlying dynamical mechanisms for that particular problem to set the necessary requirements for the simulation parameters and method (e.g. particle number and Poisson solver). Simply put, N-body simulations do not divinely reveal truth and hence their results are not infallible. They are unlikely to provide useful insight on their own, particularly for the study of even more complex secular processes such as the production of pseudo-bulges and disk heating.

Oil and democracy in Argentina, 1916-1930  

Science Conference Proceedings (OSTI)

Argentine society in the 1920s experience strong political, cultural, and economic divisions between the littoral regional surrounding Buenos Aires and the interior provinces to the west and north. Economic recession through World War 1 sparked efforts to wean the economy from total dependence upon agricultural production and export, and petroleum deposits in the south and northwest corners of Argentina offered a wider economic base. Regional conflict quickly arose concerning oil production and control over oil revenues. By mounting a popular anti-imperialist campaign against Standard Oil of New Jersey, the primary interior oil producer, dominant political forces in Buenos Aires worked to nationalize all oil deposits to the detriment of interior provincial interests. To maintain the kinds of political control necessary to fend off this threat, interior conservatives reverted to electoral fraud and violence, especially in the major oil-producing province of Salta. This thesis reconstructs and analyzes the process by which political division on the oil issue hardened and gave way to a conservative reaction leading to an authoritarian regime.

Locating of leaks in water-cooled generator stator bars using perfluorocarbon tracers  

SciTech Connect

Water cooled stator bars in power plant generators often fail during the maintenance cycle due to water leakage. After the hydrogen pressure in the generator shell has been released water can leak through cracks in the copper and through the insulation. Leaking bars, but not the leaks themselves, are detected with so-called ``hi-pot`` (high potential) tests where direct electrical current is applied to the stator bar windings. A study initiated by ConEd and Brookhaven`s Tracer Technology Center to explore the cause of these leakage problems to determine if the failures originate in the manufacturing process or are created in service by phase related torque stresses. To this purpose bars that had failed the hi-pot test were investigated first with the insulation in place and then stripped to the bare copper. The bars were pressurized with gases containing perfluorocarbon tracers and the magnitude and location of the leaks was detected by using tracers technology principles and instruments such as the ``double source`` method and the Dual Trap Analyzer. In the second part of the project the windings within a generator were tested in-situ for leaks during an outage using tracer principles. Recommendations are given suggesting the shut down of stator bar cooling water before hydrogen bleeding during outages and a revision of the current vent flow rate. The new standard should establish a reasonable leak rate for the stator bar windings proper and exclude leakage of pump seals and connections. Testing during the maintenance cycle in generators should include routine tracer leak detection following the hi-pot test.

AUTOMATIC DETECTION OF GRAVEL BARS IN A RIVER CHANNEL FROM AIRBORNE LIDAR-DERIVED DTM  

E-Print Network (OSTI)

Airborne Laser Scanning or LiDAR data are widely used nowadays in river valleys for topography and hydro-morphology. However, the large data sets of unprocessed 3D point clouds require some challenging treatment and end-users may prefer to deal with DTMs (Digital Terrain Models) derived from LiDAR surveys. Without any complementary data (such as field survey or photographs) detecting position and shape of gravel bars in a river is a demanding task, especially if done manually. This paper presents a method for automatic segmentation of a river channel into distinct hydro- morphological entities: water, gravel bars, banks,... This method is based on image processing algorithms (region growing segmentation combined with morphological closing and altitude thresholding) in order to separate water from other elements present in the channel, based on the altitude information. This method is applied to a reach of the Arcen-Maurienne River, France, with alternate gravel bars. The only data source is the 0.25 m resolution DTM, derived from an airborne LiDAR survey. Results show that the developed method succeeds in automatically delimiting the main channel and in detecting gravel bars. It is then possible to get global information on the gravel bars such as location along the river or emerged surface area and topography.

Diffractive Dijet Production in $\\bar{p}p$ Collisions at $\\sqrt{s}=1.96$ TeV  

SciTech Connect

We report on a study of diffractive dijet production in {bar p}p collisions at {radical}s = 1.96 TeV using the CDF II detector at the Fermilab Tevatron {bar p}p collider. A data sample from 310 pb{sup -1} of integrated luminosity collected by triggering on a high transverse energy jet, E{sub T}{sup jet}, in coincidence with a recoil antiproton detected in a Roman pot spectrometer is used to measure the ratio of single-diffractive to inclusive-dijet event rates as a function of x{sup {bar p}} of the interacting parton in the antiproton, the Bjorken-x, x{sub Bj}{sup {bar p}}, and a Q{sup 2} {approx} (E{sub T}{sup jet}){sup 2} in the ranges 10{sup -3} < x{sub Bj}{sup {bar p}} < 10{sup -1} and 10{sup 2} < Q{sup 2} < 10{sup 4} GeV{sup 2}, respectively. Results are presented for the region of {bar p}-momentum-loss fraction 0.03 < {zeta}{sub {bar p}} < 0.09 and a four-momentum transfer squared t{sub {bar p}} > -4 GeV{sup 2}. The t{sub {bar p}} dependence is measured as a function of Q{sup 2} and x{sub Bj}{sup {bar p}} and compared with that of inclusive single diffraction dissociation. We find weak x{sub Bj}{sup bar p}} and Q{sup 2} dependencies in the ratio of single diffractive to inclusive event rates, and no significant Q{sup 2} dependence in the diffractive t{sub {bar p}} distributions.

We set upper limits on the production cross section of such a resonance multiplied by its branching fraction to t{bar t}. We exclude a leptophobic topcolor Z' at the 95% confidence level for masses below 835 GeV (940 GeV) if its width is 1.2% (3%) of its mass. We also exclude color octet vector bosons (colorons) with masses below 775 GeV.

Multipole Field Effects for the Superconducting Parallel-Bar Deflecting/Crabbing Cavities  

SciTech Connect

The superconducting parallel-bar deflecting/crabbing cavity is currently being considered as one of the design options in rf separation for the Jefferson Lab 12 GeV upgrade and for the crabbing cavity for the proposed LHC luminosity upgrade. Knowledge of multipole field effects is important for accurate beam dynamics study of rf structures. The multipole components can be accurately determined numerically using the electromagnetic surface field data in the rf structure. This paper discusses the detailed analysis of those components for the fundamental deflecting/crabbing mode and higher order modes in the parallel-bar deflecting/crabbing cavity.

3D Hopkinson bar: new experiments for dynamic testing on soils  

E-Print Network (OSTI)

The direct analysis of the dynamic response of materials is possible using Split Hopkinson pressure bar method. For soils, it has to be adapted since the specimen has generally poor mechanical properties. An original experimental arrangement called "Three-Dimensional Split Hopkinson Pressure Bar" (3D SHPB) is proposed. It allows the measurement of the complete three-dimensional dynamic response of soils. Different types of confinement systems are used. The results on different loading paths are compared with other works on sand and clay. The analysis at grain-size level gives further elements on the comminution process.

Regularization of singular terms in $N\\bar{N}$ potential model  

E-Print Network (OSTI)

We suggest a method of singular terms regularization in potential model of $N\\bar{N}$ interaction. This method is free from any uncertainties, related to the usual cut-off procedure and based on the fact, that in the presence of sufficiently strong short-range annihilation $N$ and $\\bar{N}$ never approach close enough to each other. The effect of mentioned singular terms of OBE potential, modified by annihilation is shown to be repulsive. The obtained results for S- and P-wave scattering lengths are in agreement with existing theoretical models.

The Visibility of Galactic Bars and Spiral Structure At High Redshifts  

E-Print Network (OSTI)

We investigate the visibility of galactic bars and spiral structure in the distant Universe by artificially redshifting 101 B-band CCD images of local spiral galaxies from the Ohio State University Bright Spiral Galaxy Survey. Our artificially redshifted images correspond to Hubble Space Telescope I-band observations of the local galaxy sample seen at z=0.7, with integration times matching those of both the very deep Northern Hubble Deep Field data, and the much shallower Flanking Field observations. The expected visibility of galactic bars is probed in two ways: (1) using traditional visual classification, and (2) by charting the changing shape of the galaxy distribution in "Hubble space", a quantitative two-parameter description of galactic structure that maps closely on to Hubble's original tuning fork. Both analyses suggest that over 2/3 of strongly barred luminous local spirals i.e. objects classified as SB in the Third Reference Catalog) would still be classified as strongly barred at z=0.7 in the Hubbl...

Bar-driven fueling of galactic nuclei: a 2D view  

E-Print Network (OSTI)

I discuss evidences for bar-driven gas fueling in the central regions of galaxies, focusing on scales down to about 10 pc. I thus mention the building of inner disks, and the link with resonances, as well as the corresponding kinematic signatures such as sigma-drops and counter-rotating nuclear disks as probed via integral-field spectroscopy.

Diffractive Dijet Production in $\\bar{p}p$ Collisions at $\\sqrt{s}=1.96$ TeV  

Science Conference Proceedings (OSTI)

We report on a study of diffractive dijet production in {bar p}p collisions at {radical}s = 1.96 TeV using the CDF II detector at the Fermilab Tevatron {bar p}p collider. A data sample from 310 pb{sup -1} of integrated luminosity collected by triggering on a high transverse energy jet, E{sub T}{sup jet}, in coincidence with a recoil antiproton detected in a Roman pot spectrometer is used to measure the ratio of single-diffractive to inclusive-dijet event rates as a function of x{sup {bar p}} of the interacting parton in the antiproton, the Bjorken-x, x{sub Bj}{sup {bar p}}, and a Q{sup 2} {approx} (E{sub T}{sup jet}){sup 2} in the ranges 10{sup -3} -4 GeV{sup 2}. The t{sub {bar p}} dependence is measured as a function of Q{sup 2} and x{sub Bj}{sup {bar p}} and compared with that of inclusive single diffraction dissociation. We find weak x{sub Bj}{sup bar p}} and Q{sup 2} dependencies in the ratio of single diffractive to inclusive event rates, and no significant Q{sup 2} dependence in the diffractive t{sub {bar p}} distributions.

THE TWO-PHASE FORMATION HISTORY OF SPIRAL GALAXIES TRACED BY THE COSMIC EVOLUTION OF THE BAR FRACTION  

SciTech Connect

We study the evolution of galactic bars and the link with disk and spheroid formation in a sample of zoom-in cosmological simulations. Our simulation sample focuses on galaxies with present-day stellar masses in the 10{sup 10}-10{sup 11} M{sub Sun} range, in field and loose group environments, with a broad variety of mass growth histories. In our models, bars are almost absent from the progenitors of present-day spirals at z > 1.5, and they remain rare and generally too weak to be observable down to z Almost-Equal-To 1. After this characteristic epoch, the fractions of observable and strong bars rise rapidly, bars being present in 80% of spiral galaxies and easily observable in two thirds of these at z {<=} 0.5. This is quantitatively consistent with the redshift evolution of the observed bar fraction, although the latter is presently known up to z Almost-Equal-To 0.8 because of band-shifting and resolution effects. Our models hence predict that the decrease in the bar fraction with increasing redshift should continue with a fraction of observable bars not larger than 10%-15% in disk galaxies at z > 1. Our models also predict later bar formation in lower-mass galaxies, in agreement with existing data. We find that the characteristic epoch of bar formation, namely redshift z Almost-Equal-To 0.8-1 in the studied mass range, corresponds to the epoch at which today's spirals acquire their disk-dominated morphology. At higher redshift, disks tend to be rapidly destroyed by mergers and gravitational instabilities and rarely develop significant bars. We hence suggest that the bar formation epoch corresponds to the transition between an early 'violent' phase of spiral galaxy formation at z {>=} 1 and a late 'secular' phase at z {<=} 0.8. In the secular phase, the presence of bars substantially contributes to the growth of the (pseudo-)bulge, but the bulge mass budget remains statistically dominated by the contribution of mergers, interactions, and disk instabilities at high redshift. Early bars at z > 1 are often short-lived, while most of the bars formed at z {<=} 1 persist down to z = 0, late cosmological gas infall being necessary to maintain some of them.

Polarization Observables in $?N\\to K\\bar{K}N$  

E-Print Network (OSTI)

We explore some of the rich structure of the polarization observables recently developed for processes like $\\gamma N\\to\\pi\\pi N$ and $\\gamma N\\to K \\bar{K} N$ in the framework of a specific model for the latter process. Emphasis is placed on observables that may be accesible at existing facilities in the near future. The sensitivity of the observables to the details of the model indicate that they will be a very useful tool in differentiating between different models for reactions like these. In the framework of a model for $\\gamma N\\to K \\bar{K} N$, we examine the sensitivity of the observables to coupling constants of the $\\phi$, to the properties of the $\\Lambda(1405)$, and to the existence of the $\\Theta^+$.

Fundamental and HOM Coupler Design for the Superconducting Parallel-Bar Cavity  

Science Conference Proceedings (OSTI)

The superconducting parallel-bar cavity is currently being considered as a deflecting system for the Jefferson Lab 12 GeV upgrade and as a crabbing cavity for a possible LHC luminosity upgrade. Currently the designs are optimized to achieve lower surface fields within the dimensional constraints for the above applications. A detailed analysis of the fundamental input power coupler design for the parallel-bar cavity is performed considering beam loading and the effects of microphonics. For higher beam loading the damping of the HOMs is vital to reduce beam instabilities generated due to the wake fields. An analysis of threshold impedances for each application and impedances of the modes that requires damping are presented in this paper with the design of HOM couplers.

Nuclear Bar, Star Formation and Gas Fueling in the Active Galaxy NGC 4303  

E-Print Network (OSTI)

A combination of Hubble Space Telescope (HST) WFPC2 and NICMOS images are used to investigate the gas/dust and stellar structure inside the central 300 pc of the nearby active galaxy NGC 4303. The NICMOS H-band (F160W) image reveals a bright core and a nuclear elongated bar-like structure of 250 pc in diameter. The bar is centered on the bright core, and its major axis is oriented in proyection along the spin axis of the nuclear gaseous rotating disk recently detected (Colina & Arribas 1999). The V-H (F606W - F160W) image reveals a complex gas/dust distribution with a two-arm spiral structure of about 225 pc in radius. The southwestern arm is traced by young star-forming knots while the northeastern arm is detected by the presence of dust lanes. These spirals do not have a smooth structure but rather they are made of smaller flocculent spirals or filament-like structures. The magnitudes and colors of the star-forming knots are typical of clusters of young stars with masses of 0.5 to 1 x $10^5 M_{solar}, and ages of 5 to 25 million years. The overall structure of the nuclear spirals as well as the size, number and masses of the star-forming knots are explained in the context of a massive gaseous nuclear disk subject to self-gravitational instabilities and to the gravitational field created by the nuclear bar. According to the model, the gaseous disk has a mass of about 5 x 10^7 M_{solar} inside a radius of 400 pc, the bar has a radius of 150 pc and a pattern speed of about 0.5 Myr^{-1}, and the average mass accretion rate into the core (R < 8 pc) is about 0.01 M_{solar}$ yr^{-1} for about 80 Myr.

STAR FORMATION HISTORY IN TWO FIELDS OF THE SMALL MAGELLANIC CLOUD BAR  

SciTech Connect

The Bar is the most productive region of the Small Magellanic Cloud in terms of star formation but also the least studied one. In this paper, we investigate the star formation history of two fields located in the SW and in the NE portion of the Bar using two independent and well-tested procedures applied to the color-magnitude diagrams of their stellar populations resolved by means of deep Hubble Space Telescope photometry. We find that the Bar experienced a negligible star formation activity in the first few Gyr, followed by a dramatic enhancement from 6 to 4 Gyr ago and a nearly constant activity since then. The two examined fields differ both in the rate of star formation and in the ratio of recent over past activity, but share the very low level of initial activity and its sudden increase around 5 Gyr ago. The striking similarity between the timing of the enhancement and the timing of the major episode in the Large Magellanic Cloud is suggestive of a close encounter triggering star formation.

Optimization of Design and Manufacturing Process of Metal Foam Filled Anti-Intrusion Bars  

Science Conference Proceedings (OSTI)

The role of an anti-intrusion bar for automotive use is to absorb the kinetic energy of the colliding bodies that is partially converted into internal work of the bodies involved in the crash. The aim of this paper is to investigate the performances of a new kind of anti-intrusion bars for automotive use, filled with metallic foams. The reason for using a cellular material as a filler deals with its capacity to absorb energy during plastic deformation, while being lightweight. The study is the evolution of a previous paper presented by the authors at Esaform 2010 and will present new results and findings. It is conducted by evaluating some key technical issues of the manufacturing problem and by conducting experimental and numerical analyses. The evaluation of materials and shapes of the closed sections to be filled is made in the perspective of a car manufacturer (production costs, weight reduction, space availability in a car door, etc.). Experimentally, foams are produced starting from an industrial aluminium precursor with a TiH{sub 2} blowing agent. Bars are tested in three point bending, in order to evaluate their performances in terms of force-displacement response and other specific performance parameters. In order to understand the role of interface between the inner surface of the tube and the external surface of the foam, different kinds of interface are tested.

HERSCHEL SEARCH FOR O{sub 2} TOWARD THE ORION BAR  

Science Conference Proceedings (OSTI)

We report the results of a search for molecular oxygen (O{sub 2}) toward the Orion Bar, a prominent photodissociation region at the southern edge of the H II region created by the luminous Trapezium stars. We observed the spectral region around the frequency of the O{sub 2} N{sub J} = 3{sub 3}-1{sub 2} transition at 487 GHz and the 5{sub 4}-3{sub 4} transition at 774 GHz using the Heterodyne Instrument for the Far-Infrared on the Herschel Space Observatory. Neither line was detected, but the 3{sigma} upper limits established here translate to a total line-of-sight O{sub 2} column density <1.5 Multiplication-Sign 10{sup 16} cm{sup -2} for an emitting region whose temperature is between 30 K and 250 K, or <1 Multiplication-Sign 10{sup 16} cm{sup -2} if the O{sub 2} emitting region is primarily at a temperature of {approx}<100 K. Because the Orion Bar is oriented nearly edge-on relative to our line of sight, the observed column density is enhanced by a factor estimated to be between 4 and 20 relative to the face-on value. Our upper limits imply that the face-on O{sub 2} column density is less than 4 Multiplication-Sign 10{sup 15} cm{sup -2}, a value that is below, and possibly well below, model predictions for gas with a density of 10{sup 4}-10{sup 5} cm{sup -3} exposed to a far-ultraviolet flux 10{sup 4} times the local value, conditions inferred from previous observations of the Orion Bar. The discrepancy might be resolved if (1) the adsorption energy of O atoms to ice is greater than 800 K; (2) the total face-on A{sub V} of the Bar is less than required for O{sub 2} to reach peak abundance; (3) the O{sub 2} emission arises within dense clumps with a small beam filling factor; or (4) the face-on depth into the Bar where O{sub 2} reaches its peak abundance, which is density dependent, corresponds to a sky position different from that sampled by our Herschel beams.

Sensitivity of LHC experiments to the $t\\bar{t}H$ final state, with $H \\rightarrow b\\bar{b}$, at center of mass energy of 14 TeV  

E-Print Network (OSTI)

With the discovery of a Higgs-like particle in 2012, attention has now turned to measuring its properties, e.g., coupling to various bosonic and fermionic final states, its spin and parity, etc. In this note, we study the sensitivity of experiments at the LHC to its coupling to the top quark, by searching for the process pp $\\rightarrow t\\bar{t}H$, where the primary decay mode of the $H$ is $\\rightarrow b\\bar{b}$. In this paper, the $t\\bar{t}$ system is detected in the dilepton final state. This study is performed assuming a center of mass energy of 14 TeV and integrated luminosities of 300 fb$^{-1}$ (with an average pileup ($\\mu$) of 50 additional collisions per bunch crossing) and 3000 fb$^{-1}$ (with $\\mu=140$). We include systematic uncertainties in production cross-sections as well as the more important experimental uncertainties. Preliminary studies indicate that we will observe the $t\\bar{t}H$ final state with a significance of 2.4 and $\\ge 5.3$ for the two luminosity scenarios, respectively; addition of other $t\\bar{t}$ final states should increase the overall significance for observing $t\\bar{t}H$.

The Secular Bar-Mode Instability in Rapidly Rotating Stars Revisited  

E-Print Network (OSTI)

Uniformly rotating, homogeneous, incompressible Maclaurin spheroids that spin sufficiently rapidly are secularly unstable to nonaxisymmetric, bar-mode perturbations when viscosity is present. The intuitive explanation is that energy dissipation by viscosity can drive an unstable spheroid to a stable, triaxial configuration of lower energy - a Jacobi ellipsoid. But what about rapidly rotating compressible stars? Unlike incompressible stars, which contain no internal energy and therefore immediately liberate all the energy dissipated by viscosity, compressible stars have internal energy and can retain the dissipated energy as internal heat. Now compressible stars that rotate sufficiently rapidly and also manage to liberate this dissipated energy very quickly are known to be unstable to bar-mode perturbations, like their incompressible counterparts. But what is the situation for rapidly rotating compressible stars that have very long cooling timescales, so that all the energy dissipated by viscosity is retained as heat, whereby the total energy of the star remains constant on a secular (viscous) evolution timescale? Are such stars also unstable to the nonlinear growth of bar modes, or is the viscous heating sufficient to cause them to expand, drive down the ratio of rotational kinetic to gravitational potential energy T/|W| ~ 1/R, where R is the equatorial radius, and turn off the instability before it gets underway? If the instability still arises in such stars, at what rotation rate do they become unstable, and to what final state do they evolve? We provide answers to these questions in the context of the compressible ellipsoid model for rotating stars. The results should serve as useful guides for numerical simulations in 3+1 dimensions for rotating stars containing viscosity.

Effect of couple-stress on the pure bending of a prismatic bar  

SciTech Connect

An evaluation of the applicability of the couple-stress theory to the stress analysis of graphite structures is performed by solving a pure bending problem. The differences between solutions from the couple-stress theory and from the classical theory of elasticity are compared. It is found that the differences are sufficient to account for the inconsistencies which have often been observed between the classical elasticity theory and actual behavior of graphite under bend and tensile loadings. An experimental procedure to measure the material constants in the couple-stress theory is also suggested. The linear couple-stress theory, the origins of which go back to the turn of the last century, adds linear relations between couple-stresses and rotation gradients to the classical stress-strain law. By adopting the classical assumption that the plane cross section remains plane after deformation, the pure-bending problem is reduced to a plane couple-stress problem with traction-free boundary conditions. A general solution for an isotropic elastic prismatic bar under pure bending is then obtained using the Airy stress function and another stress function wich accounts for the couple-stresss. For a cylindrical bar, it reduces to a simple series solution. The moment-curvature and stress-curvature relations derived for a cylindrical bar from the general solution are used to examine the effect of couple-stresses. Numerical compilation of relations indicates that the couple stress parameters can be practically determined by measuring the moment-curvature ratio of various diametered specimens under bending. Although there is not sufficient data for such evaluation at present, it appears that the theory is consistent with the limited bend and tensile strength data of cylindrical specimens for H-451 graphite.

Broken Bar Detection in Synchronous Machines Based Wind Energy Conversion System  

E-Print Network (OSTI)

Electrical machines are subject to different types of failures. Early detection of the incipient faults and fast maintenance may prevent costly consequences. Fault diagnosis of wind turbine is especially important because they are situated at extremely high towers and therefore inaccessible. For offshore plants, bad weather can prevent any repair actions for several weeks. In some of the new wind turbines synchronous generators are used and directly connected to the grid without the need of power converters. Despite intensive research efforts directed at rotor fault diagnosis in induction machines, the research work pertinent to damper winding failure of synchronous machines is very limited. This dissertation is concerned with the in-depth study of damper winding failure and its traceable symptoms in different machine signals and parameters. First, a model of a synchronous machine with damper winding based on the winding function approach is presented. Next, simulation and experimental results are presented and discussed. A specially designed inside-out synchronous machine with a damper winding is employed for the experimental setup. Finally, a novel analytical method is developed to predict the behavior of the left sideband amplitude for different numbers and locations of the broken bars. This analysis is based on the magnetic field theory and the unbalanced multiphase circuits. It is found that due to the asymmetrical structure of damper winding, the left sideband component in the stator current spectrum of the synchronous machine during steady state asynchronous operation is not similar to that of the induction machine with broken bars. As a result, the motor current signature analysis (MCSA) for detection rotor failures in the induction machine is usable to detect broken damper bars in synchronous machines. However, a novel intelligent-systems based approach is developed that can identify the severity of the damper winding failure. This approach potentially can be used in a non-invasive condition monitoring system to monitor the deterioration of a synchronous motor damper winding as the number of broken bars increase over time. Some other informative features such as speed spectrum, transient time, torque-speed curve and rotor slip are also found for damper winding diagnosis.

Search for Universal Extra Dimensions in p(p)over-bar Collisions  

Science Conference Proceedings (OSTI)

We present a search for Kaluza-Klein (KK) particles predicted by models with universal extra dimensions (UED) using a data set corresponding to an integrated luminosity of 7.3 fb{sup -1}, collected by the D0 detector at a p{bar p} center-of-mass energy of 1.96 TeV. The decay chain of KK particles can lead to a final state with two muons of the same charge. This signature is used to set a lower limit on the compactification scale of R{sup -1} > 260 GeV in a minimal UED model.

Stochastic Gravitational Wave Measurements with Bar Detectors: Dependence of Response on Detector Orientation  

E-Print Network (OSTI)

The response of a cross-correlation measurement to an isotropic stochastic gravitational-wave background depends on the observing geometry via the overlap reduction function. If one of the detectors being correlated is a resonant bar whose orientation can be changed, the response to stochastic gravitational waves can be modulated. I derive the general form of this modulation as a function of azimuth, both in the zero-frequency limit and at arbitrary frequencies. Comparisons are made between pairs of nearby detectors, such as LIGO Livingston-ALLEGRO, Virgo-AURIGA, Virgo-NAUTILUS, and EXPLORER-AURIGA, with which stochastic cross-correlation measurements are currently being performed, planned, or considered.

Remedial investigation/feasibility study report for Lower Watts Bar Reservoir Operable Unit  

SciTech Connect

This document is the combined Remedial Investigation and Feasibility Study Report for the lower Watts Bar Reservoir (LWBR) Operable Unit (OU). The LWBR is located in Roane, Rhea, and Meigs counties, Tennessee, and consists of Watts Bar Reservoir downstream of the Clinch river. This area has received hazardous substances released over a period of 50 years from the US Department of Energy`s Oak Ridge Reservation (ORR), a National Priority List site established under the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA). As required by this law, the ORR and all off-site areas that have received contaminants, including LWBR, must be investigated to determine the risk to human health and the environment resulting from these releases, the need for any remedial action to reduce these risks, and the remedial actions that are most feasible for implementation in this OU. Contaminants from the ORR are primarily transported to the LWBR via the Clinch River. There is little data regarding the quantities of most contaminants potentially released from the ORR to the Clinch River, particularly for the early years of ORR operations. Estimates of the quantities released during this period are available for most radionuclides and some inorganic contaminants, indicating that releases 30 to 50 years ago were much higher than today. Since the early 1970s, the release of potential contaminants has been monitored for compliance with environmental law and reported in the annual environmental monitoring reports for the ORR.

Observation of D0-D0bar Mixing using the CDF II Detector  

E-Print Network (OSTI)

We measure the time dependence of the ratio of decay rates for D0 -> K+ pi- to the Cabibbo-favored decay D0 -> K- pi+. The charge conjugate decays are included. A signal of 3.3 x 10^4 D*+ -> pi+ D0, D0 -> K+ pi- decays is obtained with D0 proper decay times between 0.75 and 10 mean D0 lifetimes. The data were recorded with the CDF II detector at the Fermilab Tevatron and correspond to an integrated luminosity of 9.6 fb-1 for p-pbar collisions at sqrt(s) = 1.96 TeV. Assuming CP conservation, we search for D0-D0bar mixing and measure the mixing parameters to be R_D = (3.51 +/- 0.35) x 10^{-3}, y' = (4.3 +/- 4.3) x 10^{-3}, and x'^2 = (0.08 +/- 0.18) x 10^{-3}. We report Bayesian probability intervals in the x'^2 - y' plane and find that the significance of excluding the no-mixing hypothesis is equivalent to 6.1 Gaussian standard deviations, providing the second observation of D0-D0bar mixing from a single experiment.

Near-threshold production of a0(980) mesons in the reaction pp -> d K^+ \\bar{K}^0  

E-Print Network (OSTI)

Using an effective Lagrangian approach as well as the Quark-Gluon Strings Model we analyze near-threshold production of a0(980)-mesons in the reaction NN -> d K \\bar{K} as well as the background of non-resonant K\\bar{K}-pair production. We argue that the reaction pp -> d K^+ \\bar{K}^0 at an energy release Qproduction of the a0(980)-resonance. At larger energies the non-resonant K^+\\bar{K}^0-pair production - where the kaons are produced in a relative P-wave - becomes important. Then effects of final-state interactions are evaluated in a unitarized scattering-length approach and found to be in the order of a 20% suppression close to threshold. Thus in present experiments at the Cooler Synchrotron COSY-J\\"ulich for Q<=107 MeV the a_0^+ signal can reliably be separated from the non-resonant K^+\\bar{K^0} background.

Dark Matter Halos and Evolution of Bars in Disk Galaxies: Varying Gas Fraction and Gas Spatial Resolution  

E-Print Network (OSTI)

We conduct numerical experiments by evolving gaseous/stellar disks embedded in live dark matter halos aiming at quantifying the effect of gas spatial resolution and gas content on the bar evolution. Model sequences have been constructed using different resolution, and gas fraction has been varied along each sequence within fgas=0%-50%, keeping the disk and halo properties unchanged. We find that the spatial resolution becomes important with an increase in `fgas'. For the higher resolution model sequences, we observe a bimodal behavior in the bar evolution with respect to the gas fraction, especially during the secular phase of this evolution. The switch from the gas-poor to gas-rich behavior is abrupt and depends on the resolution used. The diverging evolution has been observed in nearly all basic parameters characterizing bars, such as the bar strength, central mass concentration, vertical buckling amplitude, size, etc. We find that the presence of the gas component severely limits the bar growth and affects...

Observation of the Baryonic B decay B0bar to Lambda_c^+ anti-Lambda K-  

SciTech Connect

The authors report the observation of the baryonic B decay {bar B}{sup 0} {yields} {Lambda}{sub c}{sup +} {bar {Lambda}}K{sup -} with a significance larger than 7 standard deviations based on 471 x 10{sup 6} B{bar B} pairs collected with the BABAR detector at the PEP-II storage ring at SLAC. They measure the branching fraction for the decay {bar B}{sup 0} {yields} {Lambda}{sub c}{sup +} {bar {Lambda}}K{sup -} to be (3.8 {+-} 0.8{sub stat} {+-} 0.2{sub sys} {+-} 1.0 {sub {Lambda}{sub c}{sup +}}) x 10{sup -5}. The uncertainties are statistical, systematic, and due to the uncertainty in the {Lambda}{sub c}{sup +} branching fraction. They find that the {Lambda}{sub c}{sup +} K{sup -} invariant mass distribution shows an enhancement above 3.5 GeV/c{sup 2}.

Molecular Gas in NUclei of GAlaxies (NUGA): IX. The decoupled bars and gas inflow in NGC 2782  

E-Print Network (OSTI)

We present CO(1-0) and CO(2-1) maps of the starburst/Seyfert 1 galaxy NGC 2782, obtained with the IRAM interferometer. The CO emission is aligned along the stellar nuclear bar of radius 1 kpc, configured in an elongated structure with two spiral arms at high pitch angle. At the extremity of the nuclear bar, the CO changes direction to trace two more extended spiral features at a lower pitch angle. These are the beginning of two straight dust lanes, which are aligned parallel to an oval distortion, reminiscent of a primary bar, almost perpendicular to the nuclear one. The two embedded bars appear in Spitzer IRAC near-infrared images, and HST color images, although highly obscured by dust in the latter. We compute the torques exerted by the stellar bars on the gas, and find systematically negative average torques down to the resolution limit of the images, providing evidence of gas inflow tantalizingly close to the nucleus of NGC 2782. The observations are well reproduced by numerical simulations, including gas...

Economic and Non-proliferation Policy Considerations of Uranium Enrichment in Brazil and Argentina  

Science Conference Proceedings (OSTI)

The nuclear development programs of both Argentina and Brazil have, since the 1970s, been premised on the desire for self-sufficiency and assurance of nuclear fuel supply. While military rivalry and mutual distrust led to nuclear weapons related development programs in the 1970s and 1980s, both countries have since terminated these programs. Furthermore, the governments of both countries have pledged their commitment to exclusively non-explosive use of nuclear energy and have signed the Non Proliferation Treaty (NPT). Utilizing rights provided for under the NPT, both Argentina and Brazil have nuclear fuel production facilities, with the notable exception of enrichment plants, that provide much of the current indigenous fuel requirements for their nuclear power plants. However, both countries are actively developing enrichment capability to fill this gap. The purpose of this report is to assess the economic basis and non-proliferation policy considerations for indigenous enrichment capability within the context of their desired self-sufficiency and to evaluate possible United States Government policy options.

E-Print Network (OSTI)

Using data samples of 89 fb$^{-1}$, 703 fb$^{-1}$, and 121 fb$^{-1}$ collected with the Belle detector at the KEKB asymmetric-energy $e^+e^-$ collider at center-of-mass energies 10.52 GeV, 10.58 GeV, and 10.876 GeV, respectively, we study the exclusive reactions $e^+e^- \\to \\omega\\pi^0$, $K^{\\ast}(892)\\bar{K}$, and $K_2^{\\ast}(1430)\\bar{K}$ (Charge-conjugate modes are included implicitly). Significant signals of $\\omega\\pi^0$, $K^{\\ast}(892)^0\\bar{K}^0$, and $K_2^{\\ast}(1430)^-K^+$ are observed for the first time at these energies, and the energy dependencies of the cross sections are presented. On the other hand, no significant excesses for $K^{\\ast}(892)^-K^+$ and $K_2^{\\ast}(1430)^0 \\bar{K}^0$ are found, and we set limits on the cross section ratios $R_{\\rm VP} = \\frac{\\sigma_B(e^+e^-\\to K^{\\ast}(892)^0\\bar K^0)} {\\sigma_B(e^+e^-\\to K^{\\ast}(892)^-K^+)}>$ 4.3, 20.0, and 5.4, and $R_{\\rm TP} = \\frac{\\sigma_B(e^+e^-\\to K_2^{\\ast}(1430)^0\\bar K^0)} {\\sigma_B(e^+e^-\\to K_2^{\\ast}(1430)^-K^+)}<$ 1.1, 0.4, and 0.6, for center-of-mass energies of 10.52 GeV, 10.58 GeV, and 10.876 GeV, respectively, at the 90% C.L.

Measurement of the top quark mass in $p \\bar{p}$ collisions using events with two leptons  

Science Conference Proceedings (OSTI)

We present a measurement of the top quark mass (m{sub t}) in p{bar p} collisions at {radical}s = 1.96 TeV using t{bar t} events with two leptons (ee, e{mu} or {mu}{mu}) in the final state in 4.3 fb{sup -1} of data collected with the D0 detector at the Fermilab Tevatron collider. We analyze the kinematically underconstrained dilepton events by integrating over the neutrino rapidity distributions. We reduce the dominant systematic uncertainties from jet energy calibration using a correction obtained from t{bar t} {yields} {ell} + jets events. We also correct jets in simulated events to replicate the quark flavor dependence of the jet response in data. In combination with our previous analysis, we measure m{sub t} = 174.0 {+-} 2.4(stat) {+-} 1.4(syst) GeV.

The d-bar approach to approximate inverse scattering at fixed energy in three dimensions  

E-Print Network (OSTI)

We develop the d-bar approach to inverse scattering at fixed energy in dimensions $d\\ge 3$ of [Beals, Coifman 1985] and [Henkin, Novikov 1987]. As a result we propose a stable method for nonlinear approximate finding a potential $v$ from its scattering amplitude $f$ at fixed energy $E>0$ in dimension $d=3$. In particular, in three dimensions we stably reconstruct n-times smooth potential $v$ with sufficient decay at infinity, $n>3$, from its scattering amplitude $f$ at fixed energy $E$ up to $O(E^{-(n-3-\\epsilon)/2})$ in the uniform norm as $E\\to +\\infty$ for any fixed arbitrary small $\\epsilon >0$ (that is with almost the same decay rate of the error for $E\\to +\\infty$ as in the linearized case near zero potential).

Investigation of novel decay B _____ ____(2S)____K at BaBar  

SciTech Connect

We investigate the undocumented B meson decay, B{sup +} {yields} {Psi}(2S){omega}K{sup +}. The data were collected with the BaBar detector at the SLAC PEP-II asymmetric-energy e{sup +}e{sup -} collier operating at the {gamma}(4S) resonance, a center-of-mass energy of 10.58 GeV/c{sup 2}. The {gamma}(4S) resonance primarily decays to pairs of B-mesons. The BaBar collaboration at the PEP-II ring was located at the SLAC National Accelerator Laboratory and was designed to study the collisions of positrons and electrons. The e{sup -}e{sup +} pairs collide at asymmetric energies, resulting in a center of mass which is traveling at relativistic speeds. The resulting time dilation allows the decaying particles to travel large distances through the detector before undergoing their rapid decays, a process that occurs in the in the center of mass frame over extremely small distances. As they travel through silicon vertex trackers, a drift chamber, a Cerenkov radiation detector and finally an electromagnetic calorimeter, we measure the charge, energy, momentum, and particle identification in order to reconstruct the decays that have occurred. While all well understood mesons currently fall into the qq model, the quark model has no a priori exclusion of higher configuration states such as qqqq which has led experimentalists and theorists alike to seek evidence supporting the existence of such states. Currently, there are hundreds of known decay modes of the B mesons cataloged by the Particle Data Group, but collectively they only account for approximately 60% of the B branching fraction and it is possible that many more exist.

Circumnuclear Dust in Nearby Active and Inactive Galaxies. II. Bars, Nuclear Spirals, and the Fueling of Active Galactic Nuclei  

E-Print Network (OSTI)

(Abridged) We present a detailed study of the relation between circumnuclear dust morphology, host galaxy properties, and nuclear activity in nearby galaxies. We use our sample of 123 nearby galaxies with visible--near-infrared colormaps from the Hubble Space Telescope to create well-matched, "paired" samples of 28 active and 28 inactive galaxies, as well as 19 barred and 19 unbarred galaxies, that have the same host galaxy properties. Comparison of the barred and unbarred galaxies shows that grand design nuclear dust spirals are only found in galaxies with a large-scale bar. Tightly wound nuclear dust spirals, in contrast, show a strong tendency to avoid galaxies with large-scale bars. Comparison of the AGN and inactive samples shows that nuclear dust spirals, which may trace shocks and angular momentum dissipation in the ISM, occur with comparable frequency in both active and inactive galaxies. The only difference between the active and inactive galaxies is that several inactive galaxies appear to completely lack dust structure in their circumnuclear region, while none of the AGN lack this structure. The comparable frequency of nuclear spirals in active and inactive galaxies, combined with previous work that finds no significant differences in the frequency of bars or interactions between well-matched active and inactive galaxies, suggests that no universal fueling mechanism for low-luminosity AGN operates at spatial scales greater than ~100 pc radius from the galactic nuclei. The similarities instead suggest that the lifetime of nuclear activity is less than the characteristic inflow time from these spatial scales. An order-of-magnitude estimate of this inflow time is the dynamical timescale. This sets an upper limit of several million years to the lifetime of an individual episode of nuclear activity.

Benchmarking the Bayesian reconstruction of the non-perturbative heavy $Q\\bar{Q}$ potential  

E-Print Network (OSTI)

The extraction of the finite temperature heavy quark potential from lattice QCD relies on a spectral analysis of the real-time Wilson loop. Through its position and shape, the lowest lying spectral peak encodes the real and imaginary part of this complex potential. We benchmark this extraction strategy using leading order hard-thermal loop (HTL) calculations. I.e. we analytically calculate the Wilson loop and determine the corresponding spectrum. By fitting its lowest lying peak we obtain the real- and imaginary part and confirm that the knowledge of the lowest peak alone is sufficient for obtaining the potential. We deploy a novel Bayesian approach to the reconstruction of spectral functions to HTL correlators in Euclidean time and observe how well the known spectral function and values for the real and imaginary part are reproduced. Finally we apply the method to quenched lattice QCD data and perform an improved estimate of both real and imaginary part of the non-perturbative heavy $Q\\bar{Q}$ potential.

Observation of the bottomonium ground state, eta_b, at BaBar

A peak at E_gamma = 921.2 {+2.1}{-2.8}(stat) +/- 2.4(syst) MeV observed with a significance of 10 standard deviations in the photon energy spectrum is interpretated as being due to the radiative transition Upsilon(3S) -> gamma eta_b(1S). This photon energy corresponds to an eta_b(1S) mass of 9388.9 {+3.1}{-2.3}(stat) +/- 2.7(syst) MeV/c2. The hyperfine Upsilon(1S)-eta_b(1S) mass splitting is 71.4 {+2.3}{-3.1}(stat) +/- 2.7(syst) MeV/c2. The branching fraction for this radiative \\Upsilon(3S) decay is obtained as (4.8 +/- 0.5(stat) +/- 1.2 (syst)) x 10^(-4).

Method and an apparatus to control the lateral motion of a long metal bar being formed by a mechanical process such as rolling or drawing  

DOE Patents (OSTI)

An adjustable guide, includes two or more mechanisms each having a rotatable retaining element containing a retaining groove with a variable radius in its perimeter surface. The grooves form a guidance path to control the lateral, i.e. non-axial, motion of a long bar moving along a longitudinal axis during a production process.The diameter of the guidance path varies according to the variable radii of the grooves. The guidance path increases in size at a predetermined rate, from a point of origin to an end point on the retaining groove. Rotating the retaining elements causes the diameter of the retaining grooves to change so that the size of the guidance path can be changed to match the diameter of the bar being rolled, size of the guidance path can be changed to fit the diameter of a new bar rolled without having to exchange the guide for a different sized guide, reduce fiction between the bar and the guide, a media, such as compressed air, can be injected between the retaining elements via orifices.Each retaining element is attached to a mounting apparatus. The mounting apparatus can be fixed or flexible. The flexible mounting apparatus includes one or more springs and one or more shock absorbers. A force neutral position of the flexible mounting apparatus is designed to be located on the predetermined ideal bar path line. The flexible mounting apparatus dissipates kinetic energy from the bar thereby reducing the bar's lateral motion relative to the ideal bar path line.The damping ratio of the mounting apparatus can be adjustable to alter the product's vibration mode to enable better control of the bar's lateral motion.

The Road to the Higgs in $p\\bar{p}$ collisions at $\\sqrt{s}$= 1.96 TeV  

SciTech Connect

Presented is a series of analyses which are central to the search for a low-mass Higgs boson. A search for ZZ production in the ZZ {yields} {ell}{sup -}{ell}{sup +}{nu}{bar {nu}} channel is introduced then the successful combination of this analysis with with the ZZ {yields} {ell}{sup +}{ell}{sup -}{ell}'{sup +}{ell}'{sup -} search to produce the first observation of the ZZ process at a hadron collider is then detailed. The final analysis presented is the search for the Higgs in the ZH {yields} {nu}{bar {nu}}b{bar b} channel and the interpretation as a ZZ {yields} {nu}{bar {nu}}b{bar b} search in order to validate the techniques. Common themes are discussed, such as multivariate techniques and instrumental backgrounds from energy measurement fluctuations and the tools used to combat them. The formalism of the statistical analysis of the final selected sample is introduced generally and demonstrated in the context of the above mentioned searches. The optimization of the selection through the identification of poorly reconstructed leptons is included as well as the utilization of b-quark identifying tools. Some space is given to jet reconstruction/identification and the Level 1 Calorimeter Trigger. The efficient identification and calibration of jets is central to many physics analysis especially in the low mass higgs search. Another key component of the ZH {yields} {nu}{bar {nu}}b{bar b} search is the proficient identification of jets and an imbalance of transverse energy in the first level of the triggering system. Therefore, the Level 1 Calorimeter Trigger, designed to achieve this, is a necessary component for a sensitive ZH {yields} {nu}{bar {nu}}b{bar b} search.

$W$ boson polarization measurement in the $t\\bar{t}$ dilepton channel using the CDF II Detector  

SciTech Connect

We present a measurement of W boson polarization in top-quark decays in t{bar t} events with decays to dilepton final states using 5.1 fb{sup -1} integrated luminosity in p{bar p} collisions collected by the CDF II detector at the Tevatron. A simultaneous measurement of the fractions of longitudinal (f{sub 0}) and right-handed (f{sub +}) W bosons yields the results f{sub 0} = 0.71{sub -0.17}{sup +0.18}(stat) {+-} 0.06(syst) and f{sub +} = -0.07 {+-} 0.09(stat) {+-} 0.03(syst). Combining this measurement with our previous result based on single lepton final states, we obtain f{sub 0} = 0.84 {+-} 0.09(stat) {+-} 0.05(syst) and f{sub +} = -0.16 {+-} 0.05(stat) {+-} 0.04(syst). The results are consistent with standard model expectation.

An analysis of monojet data in p{bar p} collisions at {radical}s = 1.8 TEV  

Science Conference Proceedings (OSTI)

An analysis is presented of events with a single jet and significant missing transverse energy selected from 4.7 pb{sup {minus}1} of data collected at the Fermilab Tevatron with the CDF detector. The goal is to identify events of the type p{bar p} {yields} Z{sup 0} + jet; Z{sup 0} {yields} {nu}{bar {nu}}. Event selection and backgrounds are discussed. The number of observed monojet events is compared to the number of observed Z{sup 0} {yields} e{sup +}{sup {minus}} events in which the Z{sup 0} is accompanied by a jet. We measure the number of light neutrino species to be N{sub {nu}} = 2.2{plus_minus}1.5 and we place an upper limit on the number of neutrino species at N{sub {nu}} < 5 (90% C.L.).

A study of shock mitigating materials in a split Hopkinson bar configuration. Phase 1  

Science Conference Proceedings (OSTI)

Sandia National Laboratories (SNL) designs mechanical systems with electronics that must survive high shock environments. These mechanical systems include penetrators that must survive soil, rock, and ice penetration, nuclear transportation casks that must survive transportation environments, and laydown weapons that must survive delivery impact of 125 fps. These mechanical systems contain electronics that may operate during and after the high shock environment and that must be protected from the high shock environments. A study has been started to improve the packaging techniques for the advanced electronics utilized in these mechanical systems because current packaging techniques are inadequate for these more sensitive electronics. In many cases, it has been found that the packaging techniques currently used not only do not mitigate the shock environment but actually amplify the shock environment. An ambitious goal for this packaging study is to avoid amplification and possibly attenuate the shock environment before it reaches the electronics contained in the various mechanical systems. As part of the investigation of packaging techniques, a two phase study of shock mitigating materials is being conducted. The purpose of the first phase reported here is to examine the performance of a joint that consists of shock mitigating material sandwiched in between steel and to compare the performance of the shock mitigating materials. A split Hopkinson bar experimental configuration simulates this joint and has been used to study the shock mitigating characteristics of seventeen, unconfined materials. The nominal input for these tests is an incident compressive wave with 50 fps peak (1,500 {micro}{var_epsilon} peak) amplitude and a 100 {micro}s duration (measured at 10% amplitude).

An Analysis of a Spreader Bar Crane Mounted Gamma-Ray Radiation Detection System  

E-Print Network (OSTI)

Over 95% of imports entering the United States from outside North America arrive via cargo containers by sea at 329 ports of entry. The current layered approach for the detection only scans 5% of cargo bound for the United States. This is inadequate to protect our country. This research involved the building of a gamma-ray radiation detection system used for cargo scanning. The system was mounted on a spreader bar crane (SBC) at the Port of Tacoma (PoT) and the applicability and capabilities of the system were analyzed. The detection system provided continuous count rate and spectroscopic data among three detectors while operating in an extreme environment. In a separate set of experiments, 60Co and 137Cs sources were positioned inside a cargo container and data were recorded for several count times. The Monte Carlo N-Particle (MCNP) code was used to simulate a radioactive source inside an empty cargo container and the results were compared to experimentally recorded data. The detection system demonstrated the ability to detect 60Co, 137Cs, 192Ir, highly-enriched uranium (HEU), and weapons-grade plutonium (WGPu) with minimum detectable activities (MDA) of 5.9 0.4 microcuries (?Ci), 19.3 1.1 ?Ci, 11.7 0.6 ?Ci, 3.5 0.3 kilograms (kg), and 30.6 1.3 grams (g), respectively. This system proved strong gamma-ray detection capabilities, but was limited in the detection of fissile materials Additional details of this system are presented and advantages of this approach to cargo scanning over current approaches are discussed.

Measurement of W and Z production cross-sections in p{bar p} collisions at {radical}s = 1.8 TeV  

Science Conference Proceedings (OSTI)

The cross sections for W and Z production in p{bar p} collisions at {radical}s = 1.8 TeV are measured using the D0 detector at the Fermilab Tevatron collider. The detected final states are W {yields} ev{sub e}, Z {yields} e{sup +}e{sup {minus}}, W {yields} {mu}v{sub {mu}}, and Z {yields} {mu}{sup +}{mu}{sup {minus}}. In the ratio of these measurements, many common sources of systematic error cancel and we measure R = {sigma},(p{bar p} {yields} W) {center_dot} Br(W {yields} lv)/ {sigma},(p{bar p} {yields} Z) {center_dot} Br(Z {yields} l{sup +}l{sup {minus}}). Assuming standard model couplings, this result is used to determine the width of the W bosom and to set a limit on the decay W{sup +} {yields} t{bar b}.

The authors present a search for the Higgs boson in the process q{bar q} {yields} ZN {yields} {ell}{sup +}{ell}{sup -} b{bar b}. The analysis uses an integrated luminosity of 1 fb{sup -1} of p{bar p} collisions produced at {radical}s = 1.96 TeV and accumulated by the upgraded Collider Detector at Fermilab (CDF II). They employ artificial neural networks both to correct jets mismeasured in the calorimeter, and to distinguish the signal kinematic distributions from those of the background. They see no evidence for Higgs boson production, and set 95% CL upper limits on {sigma}{sub ZH} {center_dot} {Beta}(H {yields} b{bar b}), ranging from 1.5 pb to 1.2 pb for a Higgs mass (m{sub H}) of 110 to 150 GeV/c{sup 2}.

Search for a heavy particle decaying to a top quark and a light quark in $p\\bar{p}$ collisions at $\\sqrt{s}=1.96$ TeV  

SciTech Connect

We present a search for a new heavy particle M produced in association with a top quark, p{bar p} {yields} t(M {yields} {bar t}q) or p{bar p} {yields} {bar t}({bar M} {yields} t{bar q}), where q stands for up quarks and down quarks. Such a particle may explain the recent anomalous measurements of top-quark forward-backward asymmetry. If the light-flavor quark (q) is reconstructed as a jet (j), this gives a {bar t}+j or t+j resonance in t{bar t}+jet events, a previously unexplored experimental signature. In a sample of events with exactly one lepton, missing transverse momentum and at least five jets, corresponding to an integrated luminosity of 8.7 fb{sup -1} collected by the CDF II detector, we find the data to be consistent with the standard model. We set cross-section upper limits on the production (p{bar p} {yields} Mt or {bar M} {bar t}) at 95% confidence level from 0.61 pb to 0.02 pb for M masses ranging from 200 GeV/c{sup 2} to 800 GeV/c{sup 2}, respectively.

Results of the first year of operation at Embalse Nuclear Power Station in Argentina  

SciTech Connect

As a part of the International Remote Monitoring Project, during March 1995, a Remote Monitoring System (RMS) was installed at the Embalse Nuclear Power Station in Embalse, Argentina. This system monitors the status of four typical Candu spent fuel dry storage silos. The monitoring equipment for each silo consists of analog sensors for temperature and gamma radiation measurement; digital sensors for motion detection; and electronic fiber-optic seals. The monitoring system for each silo is connected to a wireless Authenticate Item Monitoring System (AIMS). This paper describes the operation of the RMS during the first year of the trial and presents the results of the signals reported by the system compared with the on site inspections conducted by the regulatory bodies, ABACC, IAEA, ENREN. As an additional security feature, each sensor periodically transmits authenticated State-of-Health (SOH) messages. This feature provides assurance that all sensors are operational and have not been tampered with. The details of the transmitted information and the incidents of loss of SOH, referred to as Missing SOH Event, and the possible causes which produced the MSOHE are described. The RMS at the embalse facility uses gamma radiation detectors in a strong radiation field of spent fuel dry storage silos. The detectors are Geiger Muller tubes and Silicon solid state diodes. The study of the thermal drift of electronics in GM detectors and the possible radiation damage in silicon detectors is shown. Since the initial installation, the system has been successfully interrogated from Buenos Aires and Albuquerque. The experience gained, and the small changes made in the hardware in order to improve the performance of the system is presented.

The Brushless Doubly Fed Machine (BDFM) shows economic promise as a variable speed drive or generator. The optimization of the machine and model-based control strategies both rely on machine models, and the experimental verification of these models. To date, dynamic measurements of rotor quantities have not been possible. The authors present a system of measuring rotor bar currents in real time using a Rogowski coil to detect the current and recently developed Bluetooth wireless technology to transmit the data from the moving rotor to a computer. Experimental data collected from the system are included. 1.

SciTech Connect

The mutual transformation of light waves in the case of their simultaneous diffraction from a bulk reflection phase hologram, which was formed in a cubic photorefractive crystal of the 4-bar 3m symmetry class, has been studied. The indicator surfaces of the polarization-optimized values of the relative intensity of the object wave, which make it possible to determine the amplification of this wave for any crystal cut, are constructed. The linear polarization azimuths at which the energy exchange between the light waves reaches a maximum are found numerically for crystals of different cuts.

A Measurement of CP-violation Parameters in B0B0barMixing using Partially Reconstructed D^{*-}l^+ nu_l Events at BaBar  

SciTech Connect

CP violation in B{sup 0}{bar B}{sup 0} mixing is characterized by the value of the parameter |q/p| being different from 1, and the Standard Model predicts this difference to be smaller than 10{sup -3}. We present a measurement of this parameter using a partial reconstruction of one of the B mesons in the semileptonic channel D*{sup -}{ell}{sup +}{nu}{sub {ell}}, where only the hard lepton and the soft pion from the D*{sup -} {yields} {bar D}{sup 0}{pi}{sup -} decay are reconstructed. The flavor of the other B is determined by means of lepton tagging. The determination of |q/p| is then performed with a fit to the proper time difference of the two B decays. We use a luminosity of 200.8 fb{sup -1}, collected at the {Upsilon}(4S) resonance by the BABAR detector at the PEP-II asymmetrical-energy e{sup +}e{sup -} collider, in the period 1999-2004. We obtain the preliminary result: |q/p| - 1 = (6.5 {+-} 3.4(stat.) {+-} 2.0(syst.)) {center_dot} 10{sup -3}.

Testing Buda-Lund hydro model on particle correlations and spectra in NA44, WA93 and WA98 heavy ion experiments  

E-Print Network (OSTI)

Analytic and numerical approximations to a hydrodynamical model describing longitudinally expanding, cylindrically symmetric, finite systems are fitted to preliminary NA44 data measured in 200 AGeV central $S + Pb$ reactions. The model describes the measured spectra and HBT radii of pions, kaons and protons, simultaneously. The source is characterized by a central freeze-out temperature of T_0 = 154 +/- 8 +/- 11 MeV, a "surface" temperature of T_r = 107 +/- 28 +/- 18 MeV and by a well-developed transverse flow, = 0.53 +/- 0.17 +/- 0.11. The transverse geometrical radius and the mean freeze-out time are found to be R_G = 5.4 +/- 0.9 +/- 0.7 fm and tau_0 = 5.1 +/- 0.3 +/- 0.3 fm/c, respectively. Fits to preliminary WA93 200 AGeV S + Au and WA98 158 AGeV Pb + Pb data dominated by pions indicate similar model parameters. The absolute normalization of the measured particle spectra together with the experimental determination of both the statistical and the systematic errors were needed to obtain successful fits.

Consolidation of geologic studies of geopressured-geothermal resources in Texas: Barrier-bar tidal-channel reservoir facies architecture, Jackson Group, Prado field, South Texas; Final report  

DOE Green Energy (OSTI)

Sandstone reservoirs in the Jackson barrier/strandplain play are characterized by low recovery efficiencies and thus contain a large hydrocarbon resource target potentially amenable to advanced recovery techniques. Prado field, Jim Hogg County, South Texas, has produced over 23 million bbl of oil and over 32 million mcf gas from combination structural-stratigraphic traps in the Eocene lower Jackson Group. Hydrocarbon entrapment at Prado field is a result of anticlinal nosing by differential compaction and updip pinch-out of barrier bar sandstone. Relative base-level lowering resulted in forced regression that established lower Jackson shoreline sandstones in a relatively distal location in central Jim Hogg County. Reservoir sand bodies at Prado field comprise complex assemblages of barrier-bar, tidal-inlet fill, back-barrier bar, and shoreface environments. Subsequent progradation built the barrier-bar system seaward 1 to 2 mi. Within the barrier-bar system, favorable targets for hydrocarbon reexploration are concentrated in tidal-inlet facies because they possess the greatest degree of depositional heterogeneity. The purpose of this report is (1) to describe and analyze the sand-body architecture, depositional facies variations, and structure of Prado field, (2) to determine controls on distribution of hydrocarbons pertinent to reexploration for bypassed hydrocarbons, (3) to describe reservoir models at Prado field, and (4) to develop new data affecting the suitability of Jackson oil fields as possible candidates for thermally enhanced recovery of medium to heavy oil.

Study of Higgs boson production and its b-b(bar) decay in gamma-gamma processes in proton-nucleus collisions at the LHC  

SciTech Connect

We explore for the first time the possibilities to measure an intermediate-mass (m{sub H} = 115-140 GeV/c{sup 2}) Standard-Model Higgs boson in electromagnetic proton-lead (p Pb) interactions at the CERN Large Hadron Collider (LHC) via its b{bar b} decay. Using equivalent Weizsacker-Williams photon fluxes and Higgs effective field theory for the coupling {gamma}{gamma} {yields} H, we obtain a leading-order cross section of the order of 0.3 pb for exclusive Higgs production in elastic (p Pb {yields} {gamma}{gamma} p H Pb) and semielastic (p Pb {yields} {gamma}{gamma} X H Pb) processes at {radical}S{sub NN} = 8.8 TeV. After applying various kinematics cuts to remove the main backgrounds ({gamma}{gamma} {yields} b{bar b} and misidentified {gamma}{gamma} {yields} q{bar q} events), we find that a Higgs boson with m{sub H} = 120 GeV/c{sup 2} could be observed in the b{bar b} channel with a 3{sigma}-significance integrating 300 pb{sup -1} with an upgraded pA luminosity of 10{sup 31} cm{sup -2}s{sup -1}. We also provide for the first time semielastic Higgs cross sections, along with elastic t{bar t} cross sections, for electromagnetic pp, pA and AA collisions at the LHC.

Mesozoic tectonic inversion in the Neuquen Basin of west-central Argentina  

E-Print Network (OSTI)

Mesozoic tectonic inversion in the Neuquen Basin of west-central Argentina produced two main fault systems: (1) deep faults that affected basement and syn-rift strata where preexisting faults were selectively reactivated during inversion based on their length and (2) shallow faults that affected post-rift and syn-inversion strata. Normal faults formed at high angle to the reactivated half-graben bounding fault as a result of hangingwall expansion and internal deformation as it accommodated to the shape of the curved footwall during oblique inversion. Contraction during inversion was initially accommodated by folding and internal deformation of syn-rift sedimentary wedges, followed by displacement along half-graben bounding faults. We suspect that late during inversion the weight of the overburden inhibited additional fault displacement and folding became the shortening-accommodating mechanism. A Middle Jurassic inversion event produced synchronous uplift of inversion structures across the central Neuquen Basin. Later inversion events (during Late Jurassic, Early Cretaceous, and Late Cretaceous time) produced an "inversion front" that advanced north of the Huincul Arch. Synchroneity of fault reactivation during the Callovian inversion event may be related to efficient stress transmission north of the Huincul Arch, probably due to easy reactivation of low-dip listric fault segments. This required little strain accumulation along "proximal" inversion structures before shortening was transferred to more distal structures. Later inversion events found harderto- reactivate fault segments, resulting in proximal structures undergoing significant inversion before transferring shortening. The time between the end of rifting and the different inversion events may have affected inversion. Lithosphere was probably thermally weakened at the onset of the initial Callovian inversion phase, allowing stress transmission over a large distance from the Huincul Arch and causing synchronous inversion across the basin. Later inversion affected a colder and more viscous lithosphere. Significant strain needed to accumulate along proximal inversion structures before shortening was transferred to more distal parts of the basin. Timing of inversion events along the central Neuquen Basin suggest a megaregional control by right-lateral displacement motion along the Gastre Fault Zone, an intracontinental megashear zone thought to have been active prior to and during the opening of the South Atlantic Ocean.

Task 5: TVA sediment-disturbing activities within the Watts Bar Reservoir and Melton Hill Reservoir areas of the Clinch River  

DOE Green Energy (OSTI)

The objectives of Task 5 of the Interagency Agreement No. DE-AI05-91OR22007 were to review: (1) the extent of dredging, construction, and other sediment-disturbing activities conducted by the Tennessee Valley Authority (TVA) in potentially contaminated areas of Watts Bar Reservoir, and (2) the disposition of the materials from these activities. This memorandum is the final report for Task 5. This memorandum describes major activities in the Watts Bar Reservoir and Melton Hill Reservoir areas of the Clinch River that possibly resulted in significant disturbance of potentially contaminated sediments. TVA records from the construction of Watts Bar Dam, Kingston Fossil Plant, and Melton Hill Dam were reviewed to facilitate qualitative description of the effect of these activities in disturbing potentially contaminated sediments. The critical period for these activities in disturbing contaminated sediments was during or after 1956 when the peak releases of radioactive contaminants occurred from the Oak Ridge Reservation.

Measurement of the differential cross section d?/dt in elastic $p\\bar{p}$ scattering at sqrt(s)=1.96 TeV  

E-Print Network (OSTI)

We present a measurement of the elastic differential cross section $d\\sigma(p\\bar{p}\\rightarrow p\\bar{p})/dt$ as a function of the four-momentum-transfer squared t. The data sample corresponds to an integrated luminosity of $\\approx 31 nb^{-1}$ collected with the D0 detector using dedicated Tevatron $p\\bar{p} $ Collider operating conditions at sqrt(s) = 1.96 TeV and covers the range $0.26 <|t|< 1.2 GeV^2$. For $|t|<0.6 GeV^2$, d\\sigma/dt is described by an exponential function of the form $Ae^{-b|t|}$ with a slope parameter $ b = 16.86 \\pm 0.10(stat) \\pm 0.20(syst) GeV^{-2}$. A change in slope is observed at $|t| \\approx 0.6 GeV^2$, followed by a more gradual |t| dependence with increasing values of |t|.

CP violating anomalous top-quark coupling in p$\\bar{p}$ collision at $\\sqrt{s}=1.96$ TeV  

SciTech Connect

We conduct the first study of the T-odd correlations in tt events produced in p{bar p} collision at the Fermilab Tevatron collider that can be used to search for CP violation. We select events which have lepton+jets final states to identify t{bar t} events and measure counting asymmetries of several physics observables. Based on the result, we search the top quark anomalous couplings at the production vertex at the Tevatron. In addition, Geant4 development, photon identification, the discrimination of a single photon and a photon doublet from {pi}{sup 0} decay are discussed in this thesis.

Measurements of D0-D0bar Mixing and Searches for CP Violation: HFAG Combination of all Data  

E-Print Network (OSTI)

We present world average values for D0-D0bar mixing parameters x and y, CP violation parameters |q/p| and Arg(q/p), and strong phase differences \\delta and \\delta_{K\\pi\\pi}. These values are calculated by the Heavy Flavor Averaging Group (HFAG) by performing a global fit to relevant experimental measurements. The results for x and y differ significantly from zero and are inconsistent with no mixing at the level of 6.7 sigma. The results for |q/p| and Arg(q/p) are consistent with no CP violation. The strong phase difference \\delta is less than 45 degrees at 95% C.L.

Search for Long-Lived Massive Charged Particles in 1.96 TeV $\\bar{p}p}$ Collisions  

E-Print Network (OSTI)

We performed a signature-based search for long-lived charged massive particles (CHAMPs) produced in 1.0 $\\rm{fb}^{-1}$ of $\\bar{p}p$ collisions at $\\sqrt{s}=1.96$ TeV, collected with the CDF II detector using a high transverse-momentum ($p_T$) muon trigger. The search used time-of-flight to isolate slowly moving, high-$p_T$ particles. One event passed our selection cuts with an expected background of $1.9 \\pm 0.2$ events. We set an upper bound on the production cross section, and, interpreting this result within the context of a stable scalar top quark model, set a lower limit on the particle mass of 249 GeV/$c^2$ at 95% C.L.

We also present the first measurement of the longitudinal polarization fraction of the decay channel D*{sup 0}{omega}, f{sub L} = (66.5 {+-} 4.7 {+-} 1.5)%. In the above, the first uncertainty is statistical and the second is systematic. The results are based on a sample of (454 {+-} 5) x 10{sup 6} B{bar B} pairs collected at the {Upsilon}(4S) resonance, with the BABAR detector at the PEP-II storage rings at SLAC. The measurements are the most precise determinations of these quantities from a single experiment. They are compared to theoretical predictions obtained by factorization, Soft Collinear Effective Theory (SCET) and perturbative QCD (pQCD). We find that the presence of final state interactions is favored and the measurements are in better agreement with SCET than with pQCD.

E-Print Network (OSTI)

Abstract: Despite the great progress made towards smoke-free environments, only 9 % of countries worldwide mandate smoke-free restaurants and bars. Smoking was generally not regulated in restaurants and bars in China before 2008. This study was designed to examine the public attitudes towards banning smoking in these places in China. A convenience sample of 814 restaurants and bars was selected in five Chinese cities and all owners of these venues were interviewed in person by questionnaire in 2007. Eighty six percent of current nonsmoking subjects had at least one-day exposure to secondhand smoke (SHS) at work in the past week. Only 51 % of subjects knew SHS could cause heart disease. Only 17 % and 11 % of subjects supported prohibiting smoking completely in restaurants and in bars, respectively, while their support for restricting smoking to designated areas was much higher. Fifty three percent of subjects were willing to prohibit or restrict smoking in their own venues. Of those unwilling to do so, 82 % thought smokingInt. J. Environ. Res. Public Health 2011, 8 1521

Summary report on water quality, sediment and water chemistry data for water and sediment samples collected from source areas to Melton Hill and Watts Bar reservoirs  

Science Conference Proceedings (OSTI)

Contamination of surface water and sediments in the Clinch River and Watts Bar Reservoir (CR/WBR) system as a result of past and present activities by the US Department of Energy (DOE) on the Oak Ridge Reservation (ORR) and also activities by non-ORR facilities are being studied by the Clinch River Environmental Restoration Program (CR-ERP). Previous studies have documented the presence of heavy metals, organics, and radionuclides in the sediments of reservoirs in the vicinity. In support of the CR-ERP, during the summer of 1991, TVA collected and evaluated water and sediment samples from swimming areas and municipal water intakes on Watts Bar Reservoir, Melton Hill Reservoir (which is considered part of the Clinch River and Watts Bar Reservoir System), and Norris Reservoir, which was considered a source of less-contaminated reference or background data. Results of this study indicated that the levels of contamination in the samples from the Watts Bar and Melton Hill Reservoir sites did not pose a threat to human health. Despite the numerous studies, until the current work documented by this report, relatively few sediment or water samples had been collected by the CR-ERP in the immediate vicinity of contaminant point sources. This work focused on water and sediment samples taken from points immediately downstream from suspected effluent point sources both on and off the ORR. In August and September, 1994, TVA sampled surface water and sediment at twelve locations in Melton Hill and Watts Bar Reservoirs. Eleven of the sampling sites were selected based on existence of pollutant discharge permits, known locations of hazardous waste sites, and knowledge of past practices. The twelfth sample site was selected as a relatively less contaminated reference site for comparison purposes.

First Search for the Standard Model Higgs Boson Using the Semileptonic Decay Channel: H --> WW --> mu bar nu jj  

SciTech Connect

This dissertation presents the first search for the standard model Higgs boson (H) in decay topologies containing a muon, an imbalance in transverse momentum (E{sub T}) and jets, using p{bar p} collisions at {radical}s = 1.96 TeV with an integrated luminosity of 4.3 fb{sup -1} recorded with the D0 detector at the Fermilab Tevatron Collider. This analysis is sensitive primary to contributions from Higgs bosons produced through gluon fusion, with subsequent decay H {yields} WW {yields} {mu}{nu}jj where W represents a real or virtual W boson. In the absence of signal, limits are set at 95% confidence on the production and decay of the standard model Higgs boson for M{sub H} in the range of 115-200 GeV. For M{sub H} = 165 GeV, the observed and expected limits are factors of 11.2 larger than the standard model value. Combining this channel with e{nu}jj final states and including earlier data to increase the integrated luminosity to 5.4 fb{sup -1} produces observed(expected) limits of 5.5(3.8) times the standard model value.

Measurements of WW and WZ Production in W plus jets Final States in p(p)over-bar Collisions  

SciTech Connect

We study WW and WZ production with {ell}{nu}qq ({ell} = e,{mu}) final states using data collected by the D0 detector at the Fermilab Tevatron Collider corresponding to 4.3 fb{sup -1} of integrated luminosity from p{bar p} collisions at {radical}s = 1.96 TeV. Assuming the ratio between the production cross sections {sigma}(WW) and {sigma}(WZ) as predicted by the standard model, we measure the total WV (V = W,Z) cross section to be {sigma}(WV) = 19.6{sub -3.0}{sup +3.2} pb and reject the background-only hypothesis at a level of 7.9 standard deviations. We also use b-jet discrimination to separate the WZ component from the dominant WW component. Simultaneously fitting WW and WZ contributions, we measure {sigma}(WW) = 15.9{sub -3.2}{sup +3.7} pb and {sigma}(WZ) = 3.3{sub -3.3}{sup +4.1} pb, which is consistent with the standard model predictions.

Copper Heat Exchanger for the External Auxiliary Bus-Bars Routing Line in the LHC Insertion Regions  

E-Print Network (OSTI)

The corrector magnets and the main quadrupoles of the LHC dispersion suppressors are powered by a special superconducting line (called auxiliary bus-bars line N), external to the cold mass and housed in a 50 mm diameter stainless steel tube fixed to the cold mass. As the line is periodically connected to the cold mass, the same gaseous and liquid helium cools both the magnets and the line. The final sub-cooling process (from around 4.5 K down to 1.9 K) consists in the phase transformation from liquid to superfluid helium. Heat is extracted from the line through the magnets via their point of junction. In dispersion suppressor zones, approximately 40 m long, the sub-cooling of the line is slightly delayed with respect to the magnets. This might have an impact on the readiness of the accelerator for operation. In order to accelerate the process, a special heat exchanger has been designed. It is located in the middle of the dispersion suppressor portion of the line. Its main function consists in providing a loca...

THE APACHE POINT OBSERVATORY GALACTIC EVOLUTION EXPERIMENT: FIRST DETECTION OF HIGH-VELOCITY MILKY WAY BAR STARS  

Science Conference Proceedings (OSTI)

Commissioning observations with the Apache Point Observatory Galactic Evolution Experiment (APOGEE), part of the Sloan Digital Sky Survey III, have produced radial velocities (RVs) for {approx}4700 K/M-giant stars in the Milky Way (MW) bulge. These high-resolution (R {approx} 22, 500), high-S/N (>100 per resolution element), near-infrared (NIR; 1.51-1.70 {mu}m) spectra provide accurate RVs ({epsilon}{sub V} {approx} 0.2 km s{sup -1}) for the sample of stars in 18 Galactic bulge fields spanning -1 Degree-Sign -32 Degree-Sign . This represents the largest NIR high-resolution spectroscopic sample of giant stars ever assembled in this region of the Galaxy. A cold ({sigma}{sub V} {approx} 30 km s{sup -1}), high-velocity peak (V{sub GSR} Almost-Equal-To +200 km s{sup -1}) is found to comprise a significant fraction ({approx}10%) of stars in many of these fields. These high RVs have not been detected in previous MW surveys and are not expected for a simple, circularly rotating disk. Preliminary distance estimates rule out an origin from the background Sagittarius tidal stream or a new stream in the MW disk. Comparison to various Galactic models suggests that these high RVs are best explained by stars in orbits of the Galactic bar potential, although some observational features remain unexplained.

SEARCH FOR THE RARE KAON DECAY K{sup +} {yields} {pi}{sup +} {nu}{bar {nu}}  

SciTech Connect

This thesis describes the search for the rare decay K{sup +} {yields} {pi}{sup +} {nu}{bar {nu}} in the pion momentum region 140 MeV/c {le} P{sub {pi}{sup +}} {le} 195 MeV/c. This is a Flavor Changing Neutral Current (FCNC) decay which is forbidden to the first order in the Standard Model (SM) by the GIM mechanism. However, this decay mode is allowed in the second order by two Z-Penguin and one box diagram and is expected to have a branching ratio of (0.72 {+-} 0.21) x 10{sup -10}. This decay mode is sensitive to the coupling of top to down quark and therefore a measurement of the branching ratio for this decay mode provides a measurement of the Cabibbo-Kobayashi-Maskawa matrix element V{sub td}. The recent observation of two events in the pion momentum region 211 MeV/c {le} P{sup {pi}{sup +}} {le} 229 MeV/c estimates a branching ratio of 1.57{sub -0.82}{sup +1.75} x 10{sup -10} for the same decay mode. We have extended the search for this decay to the lower pion momentum region. Data collected by the Experiment E787 at Brookhaven National Laboratory during the 1996 and 1997 run were analyzed in this thesis.

$B^{(*)}\\bar B^{(*)}$ intermediate state contribution to $?(4S,5S)\\to ?_b+?$ radiative decay  

E-Print Network (OSTI)

In this work, we investigate the re-scattering effects in the radiative decay $\\Upsilon(5S)\\to\\eta_b+\\gamma$, which were suggested to be crucially important for understanding the anomalous largeness of the branching ratios $B(\\Upsilon(5S)\\to \\Upsilon(1S)+\\pi\\pi)$ and $B(\\Upsilon(5S)\\to \\Upsilon(1S)+\\eta)$. Our calculations show that the re-scattering effects may enhance $\\Gamma(\\Upsilon(10860)\\to \\eta_b+\\gamma)$ by four orders, but the tetraquark structure does not. Recently the BaBar and CLEO collaborations have measured the mass of ${\\eta_b}$ and the branching ratios $\\mathcal{B}(\\Upsilon(2S)\\rightarrow\\eta_b+\\gamma)$, $\\mathcal{B}(\\Upsilon(3S)\\rightarrow\\eta_b+\\gamma)$. We hope that very soon, $\\Upsilon(10860)\\to \\eta_b+\\gamma$ will be measured and it would be an ideal opportunity for testing whether the re-scattering or the tetraquark structure is responsible for the anomaly of $\\mathcal{B}\\big(\\Upsilon(5S)\\rightarrow\\Upsilon(nS)\\pi^+\\pi^- (n=1,2,3)\\big)$, $i.e.$, the future measurements on the radiative decays of $\\Upsilon(5S)$ might be a touchstone of the two mechanisms.

Search for Higgs bosons of the minimal supersymmetric standard model in p(p)over-bar collisions at root s=1.96 TeV  

SciTech Connect

We report results from searches for neutral Higgs bosons produced in p{bar p} collisions recorded by the D0 experiment at the Fermilab Tevatron Collider. We study the production of inclusive neutral Higgs boson in the {tau}{tau} final state and in association with a b quark in the b{tau}{tau} and bbb final states. These results are combined to improve the sensitivity to the production of neutral Higgs bosons in the context of the minimal supersymmetric standard model (MSSM). The data are found to be consistent with expectation from background processes. Upper limits on MSSM Higgs boson production are set for Higgs boson masses ranging from 90 to 300 GeV. We exclude tan {beta} > 20-30 for Higgs boson masses below 180 GeV. These are the most stringent constraints on MSSM Higgs boson production in p{bar p} collisions.

We present a search for associated production of Higgs and W bosons in p{bar p} collisions at a center of mass energy of {radical}s = 1.96 TeV in 5.3 fb{sup -1} of integrated luminosity recorded by the D0 experiment. Multivariate analysis techniques are applied to events containing one lepton, an imbalance in transverse energy, and one or two b-tagged jets to discriminate a potential WH signal from standard model backgrounds. We observe good agreement between data and background, and set an upper limit of 4.5 (at 95% confidence level and for m{sub H} = 115 GeV) on the ratio of the WH cross section multiplied by the branching fraction of H {yields} b{bar b} to its standard model prediction. A limit of 4.8 is expected from simulation.

Development and Demonstration of a High Efficiency, Rapid Heating, Low NOx Alternative to Conventional Heating of Round Steel Shapes, Steel Substrate (Strip) and Coil Box Transfer Bars  

SciTech Connect

Direct Flame Impingement involves the use of an array of very high-velocity flame jets impinging on a work piece to rapidly heat the work piece. The predominant mode of heat transfer is convection. Because of the locally high rate of heat transfer at the surface of the work piece, the refractory walls and exhaust gases of a DFI furnace are significantly cooler than in conventional radiant heating furnaces, resulting in high thermal efficiency and low NOx emissions. A DFI furnace is composed of a successive arrangement of heating modules through or by which the work piece is conveyed, and can be configured for square, round, flat, and curved metal shapes (e.g., billets, tubes, flat bars, and coiled bars) in single- or multi-stranded applications.

The longitudinal spin transfer, D{sub LL}, from high energy polarized protons to {Lambda} and {bar {Lambda}} hypersons has been measured for the first time in proton-proton collisions at {radical}s = 200 GeV with the STAR detector at RHIC. The measurements cover pseudorapidity, {eta}, in the range |{eta}| < 1.2 and transverse momenta, p{sub T}, up to 4 GeV/c. The longitudinal spin transfer is found to be D{sub LL} = -0.03{+-}0.13(stat){+-}0.04(syst) for inclusive {Lambda} and D{sub LL} = -0.12{+-}0.08(stat){+-}0.03(syst) for inclusive {bar {Lambda}} hyperons with <{eta}> = 0.5 and = 3.7 GeV/c.

Proposal to reduce greenhouse gas emissions via landfill gas management in Greater Buenos Aires, Argentina. Final report  

DOE Green Energy (OSTI)

The purpose of this project was to evaluate the feasibility of reducing the emission of greenhouse gases by collection, flaring, and possibly beneficially using the gas from landfills in Greater Buenos Aires, Argentina (GBA). Another purpose was to prepare a proposal to the US Initiative on Joint Implementation (USIJI) for a project to collect and possibly use the landfill gas (LFG). The project was carried out from September 30, 1997 through September 30, 1998. Collection and flaring of gas is feasible provided private firms have sufficient incentive to obtain greenhouse gas emission reduction benefits. The value of those benefits that would be required to motivate funding of an LFG management project was not explicitly determined. However, one independent power producer has expressed an interest in funding the first phase of the proposed project and paid for a detailed feasibility study which was conducted in August and September of 1998. As a result of this project, a proposal was submitted to the USIJI Evaluation Panel in June, 1998. In August, 1998, an office was established for reviewing and approving joint implementation proposals. The proposal is currently under review by that office.

Lineshape of $e^+ e^-\\to D^* \\bar D+c.c.$ and electromagnetic form factor of $D^*\\to D$ transition in the time-like region  

E-Print Network (OSTI)

In this work, we apply the vector meson dominance (VMD) model to extract the electromagnetic time-like form factor of the $D^*\\to D$ transition combining the recent Belle data for $e^+ e^-\\to D^{*+} D^- + c.c.$ and data for $D^*\\to D\\gamma$. Two solutions are obtained in the interpretation of the cross section lineshape: i) With a relatively large coupling for $\\psi D^*\\bar{D}$ determined by experiment, destructive interferences among those charmonium components are required to bring down the overall cross sections, and then account for the cross section lineshape. ii) With a relatively small value for the $\\psi D^*\\bar{D}$ coupling based on heavy quark theory, an apparent cross section deficit near threshold is observed, and contributions from other mechanisms are needed. It might imply the presence of an additional resonance X(3900). Meanwhile, we also point out that an enhancement like that could be produced by the $D_s^*\\bar{D_s}+c.c.$ open channel effects.

A simultaneous measurement of the $b$-tagging efficiency scale factor and the $t\\bar{t}$ Production Cross Section at the Collider Detector at Fermilab  

SciTech Connect

The ability to compare results between Monte Carlo and data is imperative in modern experimental high-energy physics analyses. The b-tagging efficiency Scale Factor (SF) allows for an accurate comparison of b quark identification in data samples and Monte Carlo. This thesis presents a simultaneous measurement of the SF for the SecVtx algorithm and the t{bar t} production cross section using 5.6 fb{sup -1} of p{bar p} collision data at {radical}s = 1.96 TeV collected by the Collider Detector at Fermilab (CDF) experiment. The t{bar t} cross section was measured to be 7.26 {+-} 0.47 pb, consistent with prior CDF analyses. The tight SF value was measured to be 0.925 {+-} 0.032 and the loose SF value was measured at 0.967 {+-} 0.033. These are the most precise SF SecVtx measurements to be performed at CDF to date.

Inspection of the unit revealed that the ground fault had been induced by fracture of one or more of the copper connectors used to join adjacent segments of one of the bus bars in the north half of the assembly. Various experimental techniques were used to detect and determine the presence of cracks, crack morphology, corrosion products, and material microstructure and/or embrittlement. The results of these inspections and recommendations are given. 7 refs., 27 figs.

(BARS) -- Bibliographic Retrieval System Sandia Shock Compression (SSC) database Shock Physics Index (SPHINX) database. Volume 1: UNIX version query guide customized application for INGRES  

SciTech Connect

The Bibliographic Retrieval System (BARS) is a data base management system specially designed to retrieve bibliographic references. Two databases are available, (i) the Sandia Shock Compression (SSC) database which contains over 5700 references to the literature related to stress waves in solids and their applications, and (ii) the Shock Physics Index (SPHINX) which includes over 8000 further references to stress waves in solids, material properties at intermediate and low rates, ballistic and hypervelocity impact, and explosive or shock fabrication methods. There is some overlap in the information in the two data bases.

Search for anomalous Wtb couplings in single top quark production in p(p)over-bar collisions at root s=1.96 TeV  

SciTech Connect

We present new direct constraints on a general Wtb interaction using data corresponding to an integrated luminosity of 5.4 fb{sup -1} collected by the D0 detector at the Tevatron p{bar p} collider. The standard model provides a purely left-handed vector coupling at the Wtb vertex, while the most general, lowest dimension Lagrangian allows right-handed vector and left- or right-handed tensor couplings as well. We obtain precise limits on these anomalous couplings by comparing the data to the expectations from different assumptions on the Wtb coupling.

Precise study of the $Z/\\gamma^*$ boson transverse momentum distribution in $p\\bar{p}$ collisions using a novel technique  

SciTech Connect

Using 7.3 fb{sup -1} of p{bar p} collisions collected by the D0 detector at the Fermilab Tevatron, we measure the distribution of the variable {phi}*{sub {eta}}, which probes the same physical effects as the Z/{gamma}* boson transverse momentum, but is less susceptible to the effects of experimental resolution and efficiency. A QCD prediction is found to describe the general features of the {phi}*{sub {eta}} distribution, but is unable to describe its detailed shape or dependence on boson rapidity. A prediction that includes a broadening of transverse momentum for small values of the parton momentum fraction is strongly disfavored.

Search for a Fermiophobic Higgs Boson Decaying into Diphotons in p p-bar Collisions at sqrt{s} = 1.96 TeV  

SciTech Connect

A search for a narrow diphoton mass resonance is presented based on data from 3.0 fb{sup -1} of integrated luminosity from p{bar p} collisions at {radical}s = 1.96 TeV collected by the CDF experiment. No evidence of a resonance in the diphoton mass spectrum is observed, and upper limits are set on the cross section times branching fraction of the resonant state as a function of Higgs boson mass. The resulting limits exclude Higgs bosons with masses below 106 GeV/c{sup 2} at a 95% Bayesian credibility level (C.L.) for one fermiophobic benchmark model.

{sup 40}K, {sup 115}Cs and {sup 226}Ra Soil and Plant Content in Seminatural Grasslands of Central Argentina  

Science Conference Proceedings (OSTI)

Activity concentrations of {sup 40}K, {sup 226}Ra and {sup 137}Cs have been analyzed in soil and plant samples, collected in permanent grassland in central Argentina. Two near areas (A1 and A2) under field conditions with soil undisturbed at least in the last four decades were selected. For each of the three studied radionuclides we do not find differences in the inventories between both areas. The inventories range from 143 kBq m{sup -2} to 197 kBq m{sup -2} for {sup 40}K and from 13 kBq m{sup -2} to 18 kBq m{sup -2} for {sup 226}Ra. The vertical distributions of {sup 40}K and {sup 226}Ra are uniform through de soil profile. For {sup 137}Cs the inventories range from 0.33 kBq m{sup -2} to 0.73 kBq m{sup -2}. In spite of {sup 137}Cs inventories are similar in both areas the distribution through vertical profile is different. {sup 137}Cs activity concentration has a maximum for layers 5-10 cm depth in A1 and 10-15 cm depth in A2. For deeper layers both areas show similar activity concentrations. The diffusion coefficient (D{sub s}) and convection velocity (v{sub s}) are estimated with a convection-diffusion model. D{sub s} values are in the range reported in the bibliography, while v{sub s} values are one order of magnitude higher. After 40 years most {sup 137}Cs fallout is still in the layer 10-15 cm depth. The great penetration of {sup 137}Cs (25 cm) in these soils may be the result of a high sand and low fine materials content. {sup 137}Cs and {sup 226}Ra were not detected in grass samples. Activity concentration of {sup 40}K in vegetal samples ranges from 116 Bq kg{sup -1} to 613 Bq kg{sup -1}. The TF values obtained for {sup 40}K show a lognormal distribution and ranges from 0.05 to 0.42.

An integrated study of the reservoir performance in the Area Central Norte (ACN) region of the Tordillo Field (Argentina)  

E-Print Network (OSTI)

The Tordillo Field is located within the San Jorge Basin of southern Argentina. The field is located within a small, dominantly extension basin, and is operated by Tecpetrol S.A., a domestic private oil company. The field produces from the El TreboL Comodoro Rivadavia, and Mina El Carmen Formations and is estimated to contain approximately 1,800 MMSTB of in-place oil. The Area Central Norte (ACN) region is a designated portion of the TordiHo Field in which a pilot waterflood was initiated in September 1993. There are immediate plans for expanding the pilot waterflood, and therefore, it is imperative that we evaluate the reservoir properties, as well as the reservoir production potential in order to design the most effective field development plan. Our integrated study of reservoir performance in the ACN pilot area, combining the geological, engineering, and reservoir performance data, is utilized to characterize the reservoir and to develop an appropriate reservoir management plan. This study win be used to determine the feasibility of expanding secondary recovery efforts throughout the Tordiflo Field by developing a reservoir description that includes the reservoir structure, rock and fluid properties, and the performance potential of the reservoir. The main focus of this work is to evaluate primary and secondary well performance in a highly stratified sequence of oil producing sands. In this study, we use rigorous methods to analyze and interpret production rate, injection rate, and pressure data from oil and water injection wells using decline type curves and estimated ultimate recovery (EUR) analysis. These methods are shown to yield excellent results for a variety of field conditions, without regard to the structure of the reservoir (shape and size), or the reservoir drive mechanism(s). Results of these analyses include the following: eservo rties: 0 Fonnation permeability, k Skin factor, s, for near-well damage or stimulation In-pplace fluid volumes: Original oil-in-place, N Reservoir drainage area, A Movable oil at current conditions, Np,,,,,, We examined the available core and modem well log data to develop an understanding for the petrophysical (k and 0) properties of the reservoir. These results will help us determine if reservoir performance is directly influenced by the geologic structure and flow characteristics of the reservoir. By combing the geological, petrophysical, and reservoir performance data in this manner, we are able to develop an integrated reservoir description for future developments as well as production optimization.

Dusky Dolphin (Lagenorhynchus obscurus) Underwater Bait-Balling Behaviors and Acoustic Signals: A Comparison Between Argentina and New Zealand  

E-Print Network (OSTI)

I characterized dusky dolphin (Lagenorhynchus obscurus) underwater bait-balling behaviors and acoustic signals, and compared data between Argentina and New Zealand (NZ) to investigate the roles of ecology versus social learning. I quantified prey herding and capturing behaviors from video footage, and I analyzed acoustic signals from narrowband recordings. In both locations, I related bait-balling behaviors and acoustic signals to group and prey ball sizes. In NZ, I also related dolphin behaviors to prey ball escape behaviors and acoustic signal parameters to examine proximate functions. Observed herding behaviors typically involved dolphins swimming around or under a prey ball using a side body orientation, while dolphins typically captured fish from the side of a prey ball using a ventral orientation. Coordinated prey-capture behaviors may have made it easier for dolphins to capture fish by trapping fish between dolphins. Signals were categorized as click trains, burst pulses, and combinations due to a bimodal inter-click interval distribution. I observed 3 whistle-like chirp-screams, but no whistles. Sequences of burst pulses also occurred that contained 2-14 burst pulses that aurally and visually appeared closely matched. Similarities between locations suggest that ecological context related to broad behavioral and acoustic parameters, while social learning differences may occur on a finer scale. In NZ, prey balls exhibited horizontal and vertical movements, but the only behavior that preceded escape was funneling, the brief formation of a ball shape where the height was at least twice the width. Dolphin behaviors that related to prey balls ascending were type of herding pass, location of prey-capture attempts, and body orientation during attempts. These behavioral parameters may also be used to counter vertical prey escape behaviors. In NZ, all signal categories had a direct or indirect role in capturing prey. Click train-burst pulses were likely used for echolocating on prey, burst pulses and sequences appeared to have communication roles, and the role of click trains was ambiguous. No signal categories appeared to have a herding function, but the sheer number of signals emitted may have caused fish to cluster together more tightly and therefore facilitated capture.

Updated Measurement of the Strong Phase in D0 --> K+pi- Decay Using Quantum Correlations in e+e- --> D0 D0bar at CLEO  

E-Print Network (OSTI)

We analyze a sample of 3 million quantum-correlated D0 D0bar pairs from 818 pb^-1 of e+e- collision data collected with the CLEO-c detector at E_cm = 3.77 GeV, to give an updated measurement of \\cos\\delta and a first determination of \\sin\\delta, where \\delta is the relative strong phase between doubly Cabibbo-suppressed D0 --> K+pi- and Cabibbo-favored D0bar --> K+pi- decay amplitudes. With no inputs from other experiments, we find \\cos\\delta = 0.81 +0.22+0.07 -0.18-0.05, \\sin\\delta = -0.01 +- 0.41 +- 0.04, and |\\delta| = 10 +28+13 -53-0 degrees. By including external measurements of mixing parameters, we find alternative values of \\cos\\delta = 1.15 +0.19+0.00 -0.17-0.08, \\sin\\delta = 0.56 +0.32+0.21 -0.31-0.20, and \\delta = (18 +11-17) degrees. Our results can be used to improve the world average uncertainty on the mixing parameter y by approximately 10%.

Search for Scalar Top Quark Production in $p\\bar{p}$ Collisions at $\\sqrt{s}=1.96$ TeV  

SciTech Connect

We report on a search for the supersymmetric partner of the top quark (scalar top) decaying into a charm quark and a neutralino in p{bar p} collisions at {radical}s = 1.96 TeV. The data sample, collected by the CDF II detector at the Fermilab Tevatron, corresponds to an integrated luminosity of 2.6 fb{sup -1}. Candidate events are selected by requiring two or more jets and a large imbalance in the transverse momentum. To enhance the analysis sensitivity, at least one of the jets is required to be identified as originating from a charm quark using an algorithm specifically designed for this analysis. The selected events are in good agreement with standard model predictions. In the case of large mass splitting between the scalar top quark and the neutralino we exclude a scalar top quark mass below 180 GeV/c{sup 2} at 95% confidence level.

Search for Higgs bosons decaying to tau(+)tau(-) pairs in p(p)over-bar collisions at root s=1.96 TeV  

Science Conference Proceedings (OSTI)

We present a search for the production of neutral Higgs bosons decaying into {tau}{sup +}{tau}{sup -} pairs in p{bar p} collisions at a center-of-mass energy of 1.96 TeV. The data, corresponding to an integrated luminosity of 5.4 fb{sup -1}, were collected by the D0 experiment at the Fermilab Tevatron Collider. We set upper limits at the 95% C.L. on the product of production cross section and branching ratio for a scalar resonance decaying into {tau}{sup +}{tau}{sup -} pairs, and we interpret these limits as limits on the production of Higgs bosons in the minimal supersymmetric standard model (MSSM) and as constraints in the MSSM parameter space.

Measurement of the inclusive jet cross section in p(p)over-bar collisions at root s=1.96 TeV  

SciTech Connect

We present a measurement of the inclusive jet cross section using the Run II cone algorithm and data collected by the D0 experiment in p{bar p} collisions at a center-of-mass energy {radical}s = 1.96 TeV, corresponding to an integrated luminosity of 0.70 fb{sup -1}. The jet energy calibration and the method used to extract the inclusive jet cross section are described. We discuss the main uncertainties, which are dominated by the jet energy scale uncertainty. The results cover jet transverse momenta from 50 GeV to 600 GeV with jet rapidities in the range -2.4 to 2.4 and are compared to predictions using recent proton parton distribution functions. Studies of correlations between systematic uncertainties in transverse momentum and rapidity are presented.

Search for High Mass Resonances Decaying to Muon Pairs in $\\sqrt{s}=1.96$ TeV $p\\bar{p}$ Collisions  

SciTech Connect

We present a search for a new narrow, spin-1, high mass resonance decaying to {mu}{sup +}{mu}{sup -} + X, using a matrix element based likelihood and a simultaneous measurement of the resonance mass and production rate. In data with 4.6 fb{sup -1} of integrated luminosity collected by the CDF detector in p{bar p} collisions at {radical}s = 1960 GeV, the most likely signal cross section is consistent with zero at 16% confidence level. We therefore do not observe evidence for a high mass resonance, and place limits on models predicting spin-1 resonances, including M > 1071 GeV/c{sup 2} at 95% confidence level for a Z{prime} boson with the same couplings to fermions as the Z boson.

Search for a Standard Model Higgs Boson in the H to ZZ to l(+)l(-)v(v)over-bar Decay Channel with the ATLAS Detector  

Science Conference Proceedings (OSTI)

A search for a heavy standard model Higgs boson decaying via H {yields} ZZ {yields} {ell}{sup +}{ell}{sup -} {nu}{bar {nu}}, where {ell} = e, {mu}, is presented. It is based on proton-proton collision data at {radical}s = 7 TeV, collected by the ATLAS experiment at the LHC in the first half of 2011 and corresponding to an integrated luminosity of 1.04 fb{sup -1}. The data are compared to the expected standard model backgrounds. The data and the background expectations are found to be in agreement and upper limits are placed on the Higgs boson production cross section over the entire mass window considered; in particular, the production of a standard model Higgs boson is excluded in the region 340 < m{sub H} < 450 GeV at the 95% confidence level.

Search for Doubly Charged Higgs Boson Pair Production in p(p)over-bar Collisions at root s=1.96 TeV  

Science Conference Proceedings (OSTI)

We present a search for pair production of doubly-charged Higgs bosons in the processes q{bar q} {yields} H{sup 2+}H{sup 2-} decaying through H{sup {+-}{+-}} {yields} {tau}{sup {+-}}{tau}{sup {+-}}, {mu}{sup {+-}}{tau}{sup {+-}}, {mu}{sup {+-}}{mu}{sup {+-}}. The search is performed in p{bar p} collisions at a center-of-mass energy of {radical}s = 1.96 TeV using an integrated luminosity of up to 7.0 fb{sup -1} collected by the D0 experiment at the Fermilab Tevatron Collider. The results are used to set 95% C.L. limits on the pair production cross section of doubly-charged Higgs bosons and on their mass for different H{sup {+-}{+-}} branching fractions. Models predicting different H{sup {+-}{+-}} decays are investigated. Assuming B(H{sup {+-}{+-}} {yields} {tau}{sup {+-}}{tau}{sup {+-}}) = 1 yields an observed (expected) lower limit on the mass of a left-handed H{sub L}{sup {+-}{+-}} boson of 128 (116) GeV and assuming {Beta}(H{sup {+-}{+-}} {yields} {mu}{sup {+-}}{tau}{sup {+-}}) = 1 the corresponding limits are 144 (149) GeV. In a model with {Beta}(H{sup {+-}{+-}} {yields} {tau}{sup {+-}}{tau}{sup {+-}}) = {Beta}(H{sup {+-}{+-}} {yields} {mu}{sup {+-}}{tau}{sup {+-}}) = {Beta}(H{sup {+-}{+-}} {yields} {mu}{sup {+-}}{mu}{sup {+-}}) = 1/3, we obtain M(H{sub L}{sup {+-}{+-}}) > 130 (138) GeV.

Measurement of D0-D0bar Mixing using the Ratio of D0->K-pi and K-K Lifetimes  

SciTech Connect

We measure the rate of D{sup 0}-{bar D}{sup 0} mixing with the observable y{sub CP} = ({tau}{sub K{pi}}/{tau}{sub KK}) - 1, where {tau}{sub KK} and {tau}{sub K{pi}} are respectively the mean lifetimes of CP-even D{sup 0} {yields} K{sup +}K{sup -} and CP-mixed D{sup 0} {yields} K{sup -}{pi}{sup +} decays, using a data sample of 384 fb{sup -1} collected by the BABAR detector at the SLAC PEP-II asymmetric-energy B Factory. From a sample of D{sup 0} and {bar D}{sup 0} decays where the initial flavor of the decaying meson is not determined, we obtain y{sub CP} = [1.12 {+-} 0.26(stat) {+-} 0.22(syst)]%, which excludes the no-mixing hypothesis at 3.3{sigma}, including both statistical and systematic uncertainties. This result is in good agreement with a previous BABAR measurement of y{sub CP} obtained from a sample of D*{sup +} {yields} D{sup 0}{pi}{sup +} events, where the D{sup 0} decays to K{sup -}{pi}{sup +}, K{sup +}K{sup -}, and {pi}{sup +}{pi}{sup -}, which is disjoint with the untagged D{sup 0} events used here. Combining the two results taking into account statistical and systematic uncertainties, where the systematic uncertainties are assumed to be 100% correlated, we find y{sub CP} = [1.16 {+-} 0.22(stat) {+-} 0.18(syst)]%, which excludes the no-mixing hypothesis at 4.1{sigma}.

Chaos and dynamical trends in barred galaxies: bridging the gap between N-body simulations and time-dependent analytical models  

E-Print Network (OSTI)

Self-consistent N-body simulations are an efficient tool to study galactic dynamics. However, it can be challenging to use them for the detailed study of individual trajectories (or ensembles of trajectories). Such orbital studies are important to shed light on global phase space properties, which are the underlying cause of observed structures. The potentials needed to describe self-consistent models are in this case time-dependent. For this reason, we aim to investigate the different dynamical properties (such as regular and chaotic motion) of a non-autonomous galactic system, whose time-dependent potential adequately mimics certain realistic trends arising from N-body barred galaxy simulations. We construct a fully time-dependent analytical model, which manages to capture and reproduce several features of an N-body simulation. We model the gravitational potentials of three components (disc, bar and dark matter halo), whose time-dependent parameters are derived from an N-body simulation. We start by studying the dynamical stability of its reduced time-independent 2-degrees of freedom model by charting the different islands of stability associated with certain orbital morphologies and detecting the chaotic and regular regions. We then turn our interest to the full 3-degrees of freedom time-dependent case, where we show a few representative trajectories which experience different typical dynamical behaviours, i.e., an interplay between regular and chaotic motion for different epochs. Finally, we focus on the study of the underlying global dynamical transitions of the time-dependent system in terms of estimating the relative total fraction of (un)stable motion of an ensemble of initial conditions taken from the simulation and evolved with the time-dependent potential. We find that, for such an ensemble, the fraction of regular motion increases with time.

Studies of the Strange Hadronic Tau Decay Tau- to K0(S) Pi- Nu-Tau Using the BaBar Detector  

SciTech Connect

A study of the decay {tau}{sup -} {yields} K{sub S}{sup 0}{pi}{sup -} {nu}{sub {tau}} (K{sub S}{sup 0} {yields} {pi}{sup +}{pi}{sup -}) using the BABAR detector is presented. Using 124.4 fb{sup -1} of data we measure {Beta}({tau}{sup -} {yields} {bar K}{sup 0}{pi}{sup -}{nu}{sub {tau}}) = (0.830 {+-} 0.005(stat) {+-} 0.042(syst))%, which is the world's most precise measurement to date of this branching ratio, and is consistent with the current world average. This preliminary result, unlike most of the {Beta}({tau}{sup -} {yields} {bar K}{sup 0}{pi}{sup -}{nu}{sub {tau}}) measurements already published, is systematics dominated and so the biggest future improvement to this number should come from reducing the systematic uncertainties in the analysis. A study of the K{pi} mass spectrum, from which the strange (K{pi}) spectral function can be measured, reveals excess contributions above the K*(892) tail at higher K{pi} mass. While in the past this has been thought to be due to K*(892) - K*(1410) interference, we find that the K*(1410), whose branching ratio to K{pi} is approximately 7%, seems insufficient to explain the excess mass observed in the data. Instead, we perform a fit using a K*(892) - K*(1680) interference model and find better agreement. The discrepancy that remains could be due to an s-wave contribution to the interference that is not parameterized in the model used, and/or detector smearing that is not accounted for in our fit. We also attempt to find an s-wave contribution to the K{pi} mass spectrum by searching for an sp-interference effect. While we find a hint that such an effect exists, we have neither the confidence in the statistics nor systematics in the higher K{pi} mass region to announce an observation. We conclude that it would be a worthwhile study to pursue.

Investigation Of The Friction Factor Behavior for Flat Plate Tests Of Smooth And Roughened Surfaces With Supply Pressures Up To 84 Bars  

E-Print Network (OSTI)

Annular gas seal clearances were simulated with closely spaced parallel plates using a Flat?Plate tester. The device is designed to measure the pressure gradient along the test specimen. The main function of the Flat?Plate tester is to provide friction factor data and measure dynamic pressure oscillations. A detailed description of the test facility is described, and a theory for determining the friction factor is reviewed. Three clearances were investigated: 0.635, 0.381, and 0.254 mm. Tests were conducted at three different inlet pressures (84, 70, and 55 bars), producing Reynolds numbers range from 50,000 to 700,000. Three surface configurations were tested including smooth?on-smooth, smooth?on?hole, and hole?on?hole. The Hole?pattern plates are identical with the exception of the hole depth. The results indicate that, for the smooth?on?smooth and smooth?on?hole configurations, the friction factor remains constant or increases slightly with increasing Reynolds numbers. Moreover, the friction factor increases as the clearance between the plates increases. However, the results from the hole?on-hole configurations are quite different. A "friction?factor jump" phenomenon was observed, and the Helmholtz frequency was detected on the frequency spectra.

Measurement of D^0-\\bar{D^0} Mixing From a Time-Dependent Amplitude Analysis of D^0\\ -> K^+\\pi^-\\pi0 Decays  

SciTech Connect

The authors present evidence of D{sup 0}-{bar D}{sup 0} mixing using a time-dependent amplitude analysis of the decay D{sup 0} {yields} K{sup +}{pi}{sup -}{pi}{sup 0} in a data sample of 384 fb{sup -1} collected with the BABAR detector at the PEP-II e{sup +}e{sup -} collider at SLAC. Assuming CP conservation, they measure the mixing parameters x{prime}{sub K{pi}{pi}{sup 0}} = [2.61{sub -0.68}{sup +0.57}(stat.) {+-} 0.39(syst.)]%, y{prime}{sub K{pi}{pi}{sup 0}} = [-0.06{sub -0.64}{sup +0.55}(stat.) {+-} 0.34(syst.)]%. The confidence level for the data to be consistent with the no-mixing hypothesis is 0.1%, including systematic uncertainties. This result is inconsistent with the no-mixing hypothesis with a significance of 3.2 standard deviations. They find no evidence of CP violation in mixing.

Searches for the Theta_s(1540)+ Strange-Pentaquark Candidate in e+e- Annihilation, Hadroproduction and Electroproduction with the BaBar Detector  

SciTech Connect

Since early in 2003, several experiments have presented evidence for the existence of a positive strangeness baryon state of mass around 1540 MeV/c{sup 2} and width <8 MeV, the {Theta}(1540), which decays to K{sup +}n and K{sup 0}p. Such a state has minimum quark content udud{bar s} and consequently has been interpreted as the S = +1 member of the anti-decuplet of pentaquark states proposed by Diakonov et al. Subsequently, the NA49 experiment presented evidence for the S = -2 member of the anti-decuplet, the {Xi}{sub 5}(1860){sup --}, but this has yet to be observed in any other experiment. Results from the search for the production of the {Theta}(1540) memember of the anti-decuplet of pentaquark states using data from e{sup +}e{sup -} collisions obtained with the BABAR detector at the PEP-II Collider are presented. No signal is observed, and cross section limits for the {Theta}(1540) are given; these prove to be well below the cross section values for ordinary baryons of similar mass. In addition, a search has been carried out for the electroproduction of the {Theta}(1540) in the material of the BABAR detector. Event selection procedures are discussed in detail, the results of this search are presented, and are discussed in the light of several other experiments.

Search for $WH$ associated production in $p \\bar{p}$ collisions at $\\sqrt{s}=1.96\\,{\\rm TeV}$  

SciTech Connect

This report describes a search for associated production of W and Higgs bosons based on data corresponding to an integrated luminosity of L {approx} 5.3 fb{sup -1} collected with the D0 detector at the Fermilab Tevatron p{bar p} Collider. Events containing a W {yields} {ell}{nu} candidate (with {ell} corresponding to e or {mu}) are selected in association with two or three reconstructed jets. One or two of the jets are required to be consistent with having evolved from a b quark. A multivariate discriminant technique is used to improve the separation of signal and backgrounds. Expected and observed upper limits are obtained for the product of the WH production cross section and branching ratios and reported in terms of ratios relative to the prediction of the standard model as a function of the mass of the Higgs boson (M{sub H}). The observed and expected 95% C.L. upper limits obtained for an assumed M{sub H} = 115 GeV are, respectively, factors of 4.5 and 4.8 larger than the value predicted by the standard model.

Prospects for Observing the Standard Model Higgs Boson Decaying into b\\bar{b} Final States Produced in Weak Boson Fusion with an Associated Photon at the LHC  

E-Print Network (OSTI)

One of the primary goals of the Large Hadron Collider is to understand the electroweak symmetry breaking mechanism. In the Standard Model, electroweak symmetry breaking is described by the Higgs mechanism which includes a scalar Higgs boson. Electroweak measurements constrain the Standard Model Higgs boson mass to be in the 114.4 to 157 GeV/c^2 range. Within this mass window, the Higgs predominantly decays into two b-quarks. As such, we investigate the prospect of observing the Standard Model Higgs decaying to b\\bar{b} produced in weak-boson-fusion with an associated central photon. An isolated, high pt, central photon trigger is expected to be available at the ATLAS and CMS experiments. In this study, we investigated the effects originating from showering, hadronization, the underlying event model, and jet performance including b-jet calibration on the sensitivity of this channel. We found that the choice of Monte Carlo and Monte Carlo tune has a large effect on the efficacy of the central jet veto and consequently the signal significance. A signal significance of about 1.86 can be achieved for m(Higgs)=115 GeV/c^2 with 100 1/fb of integrated luminosity which correspond to one year at design luminosity at 14 TeV pp collisions.

CO{sub 2} emissions from developing countries: Better understanding the role of Energy in the long term. Volume 2, Argentina, Brazil, Mexico, and Venezuela  

Science Conference Proceedings (OSTI)

Recent years have witnessed a growing recognition of the link between emissions of carbon dioxide (CO{sub 2}) and changes in the global climate. Of all anthropogenic activities, energy production and use generate the single largest portion of these greenhouse gases. Although developing countries currently account for a small share of global carbon emissions, their contribution is increasing rapidly. Due to the rapid expansion of energy demand in these nations, the developing world`s share in global modern energy use rose from 16 to 27 percent between 1970 and 1990. If the growth rates observed over the past 20 years persist energy demand in developing will surpass that in the countries of the Organization for Economic Cooperation and Development (OECD) early in the 21st century. The study seeks to examine the forces that galvanize the growth of energy use and carbon emissions, to assess the likely future levels of energy and CO{sub 2} in selected developing nations and to identify opportunities for restraining this growth. The purpose of this report is to provide the quantitative information needed to develop effective policy options, not to identify the options themselves. These individual studies were conducted fro Argentina, Brazil, Mexico and Venezuela in Latin America.

Model-independent measurement of t-channel single top quark production in p(p)over-bar collisions at,root s=1.96 TeV  

SciTech Connect

We present a model-independent measurement of t-channel electroweak production of single top quarks in p{bar p} collisions at {radical}s = 1.96 TeV. Using 5.4 fb{sup -1} of integrated luminosity collected by the D0 detector at the Fermilab Tevatron Collider, and selecting events containing an isolated electron or muon, missing transverse energy and one or two jets originating from the fragmentation of b quarks, we measure a cross section {sigma}(p{bar p} {yields} tqb + X) = 2.90 {+-} 0.59 (stat + syst) pb for a top quark mass of 172.5 GeV. The probability of the background to fluctuate and produce a signal as large as the one observed is 1.6 x 10{sup -8}, corresponding to a significance of 5.5 standard deviations.

Cesium/oxide interactions for ultrathin films on {alpha}-Al{sub 2}O{sub 3}(0001) and {alpha}-Al{sub 2}O{sub 3}(1{bar 1}02)  

DOE Green Energy (OSTI)

The interaction of cesium at the (0001) and (1{bar 1}02) surfaces of sapphire has been investigated using a variety of surface analytical techniques. Reflection mass spectrometric measurements yield initial Cs adsorption probabilities of 0.9 and 0.85 for the unreconstructed (0001) and (1{bar 1}02) surfaces, respectively. The adsorption probability decreases dramatically for these surfaces at critical Cs coverages of 2.O {times} 10{sup 14} and 3.4 {times} 10{sup 14} atoms/cm{sup 2}, respectively. Thermally induced reconstruction of the (0001) surface to form an oxygen deficient surface results in a decrease in the initial probability and capacity for Cs adsorption. Low energy electron diffraction (LEED) demonstrates that an intermediate, mixed domain surface yields an initial adsorption probability of 0.5 while a ({radical}31 {times} {radical}31) R {plus_minus} 9{degree} reconstructed surface yields a value of 0.27. Thermal desorption mass spectrometry (TDMS) shows that surface reconstruction eliminates the high binding energy states of Cs (2.7 eV/atom), consistent with the observed changes in adsorption probability. In contrast, reconstruction of the (1{bar 1}02) surface produces only minor changes in Cs adsorption. X-ray photoelectron spectroscopy (XPS) indicates that no formal reductive/oxidative chemistry takes place at the interface. We interpret the facile adsorption and strong binding of Cs on sapphire to result from Cs interacting with coordinatively unsaturated oxygen.

Search for Standard Model Higgs Boson Production in Association with a $W$ Boson Using a Matrix Element Technique at CDF in $p\\bar{p}$ Collisions at $\\sqrt{s} = 1.96$ TeV  

Science Conference Proceedings (OSTI)

This paper presents a search for standard model Higgs boson production in association with a W boson using events recorded by the CDF experiment in a dataset corresponding to an integrated luminosity of 5.6 fb{sup -1}. The search is performed using a matrix element technique in which the signal and background hypotheses are used to create a powerful discriminator. The discriminant output distributions for signal and background are fit to the observed events using a binned likelihood approach to search for the Higgs boson signal. We find no evidence for a Higgs boson, and 95% confidence level (C.L.) upper limits are set on {sigma}(p{bar p} {yields} WH) x {Beta}(H {yields} b{bar b}). The observed limits range from 3.5 to 37.6 relative to the standard model expectation for Higgs boson masses between m{sub H} = 100 GeV/c{sup 2} and m{sub H} = 150 GeV/c{sup 2}. The 95% C.L. expected limit is estimated from the median of an ensemble of simulated experiments and varies between 2.9 and 32.7 relative to the production rate predicted by the standard model over the Higgs boson mass range studied.

(2003) to compute the mutual solubilities of CO 2 and H 2 O are extended to include the effect of chloride salts in the aqueous phase. This is accomplished by including, in the original formulation, activity coefficients for aqueous CO 2 derived from several literature sources, primarily for NaCl solutions. Best results are obtained when combining the solubility correlations of Spycher et al. (2003) with the activity coefficient formulation of Rumpf et al. (1994) and Duan and Sun (2003), which

Measurement of the $\\Lambda_b^0$ lifetime in the exclusive decay $\\Lambda_b^0 \\to J/\\psi \\Lambda^0$ in $p\\bar{p}$ collisions at $\\sqrt{s}=1.96$ TeV  

Science Conference Proceedings (OSTI)

We measure the {Lambda}{sub b}{sup 0} lifetime in the fully reconstructed decay {Lambda}{sub b}{sup 0} {yields} J/{psi} {Lambda}{sup 0} using 10.4 fb{sup -1} of p{bar p} collisions collected with the D0 detector at {radical}s = 1.96 TeV. The lifetime of the topologically similar decay channel B{sup 0} {yields} J/{psi} K{sub S}{sup 0} is also measured. We obtain {tau} ({Lambda}{sub b}{sup 0}) = 1.303 {+-} 0.075 (stat.) {+-} 0.035 (syst.) ps and {tau} (B{sup 0}) = 1.508 {+-} 0.025 (stat.) {+-} 0.043 (syst.) ps. Using these measurements, we determine the lifetime ratio of {tau} ({Lambda}{sub b}{sup 0})/{tau} (B{sup 0}) = 0.864 {+-} 0.052 (stat.) {+-} 0.033 (syst.).

Measurement of the CP-violating phase phi sJ/psi phi using the flavor-tagged decay Bs(0) -> J/psi phi in 8 fb(-1) of p(p)over-bar collisions  

SciTech Connect

We report an updated measurement of the CP-violating phase, {phi}{sub s}{sup J/{psi}{phi}} and the decay-width difference for the two mass eigenstates, {Delta}{Gamma}{sub s}, from the flavor-tagged decay B{sub s}{sup 0} {yields} J/{psi}{phi}. The data sample corresponds to an integrated luminosity of 8.0 fb{sup -1} accumulated with the D0 detector using p{bar p} collisions at {radical}s = 1.96 TeV produced at the Fermilab Tevatron collider. The 68% Bayesian credibility intervals, including systematic uncertainties, are {Delta}{Gamma}{sub s} = 0.163{sub -0.064}{sup +0.065} ps{sup -1} and {phi}{sub s}{sup J}/{psi}{phi} = -0.55{sub -0.36}{sup +0.38}. The p-value for the Standard Model point is 29.8%.

Search for a low mass Standard Model Higgs boson in the $\\tau-\\tau$ decay channel in $p\\bar{p}$ collisions at $\\sqrt{s}$ = 1.96 TeV  

Science Conference Proceedings (OSTI)

We report on a search for the standard model Higgs boson decaying into pairs of {tau} leptons in p{bar p} collisions produced by the Tevatron at {radical}s = 1.96 TeV. The analyzed data sample was recorded by the CDFII detector and corresponds to an integrated luminosity of 6.0 fb{sup -1}. The search is performed in the final state with one {tau} decaying leptonically and the second one identified through its semi-hadronic decay. Since no significant excess is observed, a 95% credibility level upper limit on the production cross section times branching ratio to the {tau}{tau} final state is set for hypothetical Higgs boson masses between 100 and 150 GeV/c{sup 2}. For a Higgs boson of 120 GeV/c{sup 2} the observed (expected) limit is 14.6 (15.3) the predicted value.

Search for the Standard Model Higgs Boson Produced in Association with a $Z$ Boson in $p\\bar{p}$ Collisions at $\\sqrt{s} = 1.96$ TeV  

Science Conference Proceedings (OSTI)

We present a search for the standard model Higgs boson produced in association with a Z boson, using up to 7.9 fb{sup -1} of integrated luminosity from p{bar p} collisions collected with the CDF II detector. We utilize several novel techniques, including multivariate lepton selection, multivariate trigger parametrization, and a multi-stage signal discriminant consisting of specialized functions trained to distinguish individual backgrounds. By increasing acceptance and enhancing signal discrimination, these techniques have significantly improved the sensitivity of the analysis above what was expected from a larger dataset alone. We observe no significant evidence for a signal, and we set limits on the ZH production cross section. For a Higgs boson with mass 115 GeV/c{sup 2}, we expect (observe) a limit of 3.9 (4.8) times the standard model predicted value, at the 95% credibility level.

The standard model of particle physics provides a detailed description of a universe in which all matter is composed of a small number of fundamental particles, which interact through the exchange of force - carrying gauge bosons (the photon, W{sup {+-}}, Z and gluons). The organization of the matter and energy in this universe is determined by the effects of three forces; the strong, weak, and electromagnetic. The weak and electromagnetic forces are the low energy manifestations of a single electro-weak force, while the strong force binds quarks into protons and neutrons. The standard model does not include gravity, as the effect of this force on fundamental particles is negligible. Four decades of experimental tests, spanning energies from a few electron-volts (eV) up to nearly two TeV, confirm that the universe described by the standard model is a reasonable approximation of our world. For example, experiments have confirmed the existence of the top quark, the W{sup {+-}} and the Z bosons, as predicted by the standard model. The latest experimental averages for the masses of the top quark, W{sup {+-}} and Z are respectively 173.1 {+-} 0.6(stat.) {+-} 1.1(syst.), 80.399 {+-} 0.023 and 91.1876 {+-} 0.0021 GeV/c{sup 2}. The SM is a gauge field theory of zero mass particles. However, the SM is able to accommodate particles with non-zero mass through the introduction of a theoretical Higgs field which permeates all of space. Fermions gain mass through interactions with this field, while the longitudinal components of the massive W{sup {+-}} and Z are the physical manifestations of the field itself. Introduction of the Higgs field, directly leads to the predicted existence of an additional particle, the Higgs boson. The Higgs boson is the only particle of the standard model that has not been observed, and is the only unconfirmed prediction of the theory. The standard model describes the properties of the Higgs boson in terms of its mass, which is a free parameter in the theory. Experimental evidence suggests that the Higgs mass has a value between 114.4 and 186 GeV/c{sup 2}. Particles with a mass in this range can be produced in collisions of less massive particles accelerated to near the speed of light. Currently, one of only a few machines capable of achieving collision energies large enough to potentially produce a standard model Higgs boson is the Tevatron proton-antiproton collider located at Fermi National Accelerator Laboratory in Batavia, Illinois. This dissertation describes the effort to observe the standard model Higgs in Tevatron collisions recorded by the Collider Detector at Fermilab (CDF) II experiment in the ZH {yields} {ell}{sup +}{ell}{sup -}b{bar b} production and decay channel. In this process, the Higgs is produced along with a Z boson which decays to a pair of electrons or muons (Z {yields} {ell}{sup +}{ell}{sup -}), while the Higgs decays to a bottom anti-bottom quark pair (H {yields} b{bar b}). A brief overview of the standard model and Higgs theory is presented in Chapter 2. Chapter 3 explores previous searches for the standard model Higgs at the Tevatron and elsewhere. The search presented in this dissertation expands upon the techniques and methods developed in previous searches. The fourth chapter contains a description of the Tevatron collider and the CDF II detector. The scope of the discussion in Chapter 4 is limited to the experimental components relevant to the current ZH {yields} {ell}{sup +}{ell}{sup -}b{bar b} search. Chapter 5 presents the details of object reconstruction; the methods used to convert detector signals into potential electrons, muons or quarks. Chapter six describes the data sample studied for the presence of a ZH {yields} {ell}{sup +}{ell}{sup -}b{bar b} signal and details the techniques used to model the data. The model accounts for both signal and non-signal processes (backgrounds) which are expected to contribute to the observed event sample. Chapters 7 and 8 summarize the event selection applied to isolate ZH {yields} {ell}{sup +}{ell}{sup -}b{bar b} candidate events

We search for the Z{sub 1}(4050){sup +} and Z{sub 2}(4250){sup +} states, reported by the Belle Collaboration, decaying to {chi}{sub c1}{pi}{sup +} in the decays {bar B}{sup 0} {yields} {chi}{sub c1}K{sup -}{pi}{sup +} and B{sup +} {yields} {chi}{sub c1}K{sub S}{sup 0}{pi}{sup +} where {chi}{sub c1} {yields} J/{psi}{gamma}. The data were collected with the BABAR detector at the SLAC PEP-II asymmetric-energy e{sup +}e{sup -} collider operating at center-of-mass energy 10.58 GeV, and correspond to an integrated luminosity of 429 fb{sup -1}. In this analysis, we model the background-subtracted, efficiency-corrected {chi}{sub c1}{pi}{sup +} mass distribution using the K{pi} mass distribution and the corresponding normalized K{pi} Legendre polynomial moments, and then test the need for the inclusion of resonant structures in the description of the {chi}{sub c1}{pi}{sup +} mass distribution. No evidence is found for the Z{sub 1}(4050){sup +} and Z{sub 2}(4250){sup +} resonances, and 90% confidence level upper limits on the branching fractions are reported for the corresponding B-meson decay modes.

Preliminary measurements of the time dependence of B{sub d}{sup 0} - {bar B}{sub d}{sup 0} mixing with kaon and charge dipole tags  

SciTech Connect

We report two preliminary measurements of the time dependence of B{sub d}{sup 0}- B{sub d}{sup 0} mixing using novel techniques with a sample of 150,000 hadronic Z{sup O} decays collected by the SLD experiment at the SLC. B decay vertices are reconstructed inclusively with a topological technique and the B hadron flavor at production is determined by exploiting the large left-right forward-backward asymmetry of Z{sup O} {r_arrow} b {bar b} decays in combination with a jet charge technique. Two methods are used to tag the B flavor at decay. The first uses the charge of kaons attached to the B decay vertex and identified with the Cherenkov Ring Imaging Detector. The second measurement is based on the construction of a charge dipole of the topological vertices to separate the B{sub d}{sup O}/B{sub d}{sup 0} decays by exploiting the B {r_arrow} D cascade charge structure. The measurement of the oscillation frequency yields {Delta}m{sub d} = 0.58 {+-} 0.07(stat){+-}0.08(syst) ps{sup -1} and 0.56 {+-} 0.08(stat){+-}0.04(syst) ps{sup {minus}1} for the kaon and dipole tags respectively.

We report on a search for the standard model Higgs boson produced in association with a W or Z boson in p{bar p} collisions at {radical}s = 1.96 TeV recorded by the CDF II experiment at the Tevatron in a data sample corresponding to an integrated luminosity of 2.1 fb{sup -1}. We consider events which have no identified charged leptons, an imbalance in transverse momentum, and two or three jets where at least one jet is consistent with originating from the decay of a b hadron. We find good agreement between data and predictions. We place 95% confidence level upper limits on the production cross section for several Higgs boson masses ranging from 110 GeV/c{sup 2} to 150 GeV/c{sup 2}. For a mass of 115 GeV/c{sup 2} the observed (expected) limit is 6.9 (5.6) times the standard model prediction.

Measurements of Time-Dependent CP-Asymmetry Parameters in B Meson Decays to \\eta^{\\prime} K^0 and of Branching Fractions of SU(3) Related Modes with BaBar Experiment at SLAC  

Science Conference Proceedings (OSTI)

In this thesis work we have measured the following upper limits at 90% of confidence level, for B meson decays (in units of 10{sup -6}), using a statistics of 465.0 x 10{sup 6} B{bar B} pairs: {Beta}(B{sup 0} {yields} {eta}K{sup 0}) < 1.6 {Beta}(B{sup 0} {yields} {eta}{eta}) < 1.4 {Beta}(B{sup 0} {yields} {eta}{prime}{eta}{prime}) < 2.1 {Beta}(B{sup 0} {yields} {eta}{phi}) < 0.52 {Beta}(B{sup 0} {yields} {eta}{omega}) < 1.6 {Beta}(B{sup 0} {yields} {eta}{prime}{phi}) < 1.2 {Beta}(B{sup 0} {yields} {eta}{prime}{omega}) < 1.7 We have no observation of any decay mode, statistical significance for our measurements is in the range 1.3-3.5 standard deviation. We have a 3.5{sigma} evidence for B {yields} {eta}{omega} and a 3.1 {sigma} evidence for B {yields} {eta}{prime}{omega}. The absence of observation of the B{sup 0} {yields} {eta}K{sup 0} open an issue related to the large difference compared to the charged mode B{sup +} {yields} {eta}K{sup +} branching fraction, which is measured to be 3.7 {+-} 0.4 {+-} 0.1 [118]. Our results represent substantial improvements of the previous ones [109, 110, 111] and are consistent with theoretical predictions. All these results were presented at Flavor Physics and CP Violation (FPCP) 2008 Conference, that took place in Taipei, Taiwan. They will be soon included into a paper to be submitted to Physical Review D. For time-dependent analysis, we have reconstructed 1820 {+-} 48 flavor-tagged B{sup 0} {yields} {eta}{prime}K{sup 0} events, using the final BABAR statistic of 467.4 x 10{sup 6} B{bar B} pairs. We use these events to measure the time-dependent asymmetry parameters S and C. We find S = 0.59 {+-} 0.08 {+-} 0.02, and C = -0.06 {+-} 0.06 {+-} 0.02. A non-zero value of C would represent a directly CP non-conserving component in B{sup 0} {yields} {eta}{prime}K{sup 0}, while S would be equal to sin2{beta} measured in B{sup 0} {yields} J/{psi}K{sub s}{sup 0} [108], a mixing-decay interference effect, provided the decay is dominated by amplitudes of a single weak phase. The new measured value of S can be considered in agreement with the expectations of the 'Standard Model', inside the experimental and theoretical uncertainties. Inconsistency of our result for S with CP conservation (S = 0) has a significance of 7.1 standard deviations (statistical and systematics included). Our result for the direct-CP violation parameter C is 0.9 standard deviations from zero (statistical and systematics included). Our results are in agreement with the previous ones [18]. Despite the statistics is only 20% larger than the one used in previous measurement, we improved of 20% the error on S and of 14% the error on C. This error is the smaller ever achieved, by both BABAR and Belle, in Time-Dependent CP Violation Parameters measurement is a b {yields} s transition.

Charmonium physics from {bar p}p interactions  

SciTech Connect

Heavy quarkonium is perhaps the best QCD laboratory in existence. Much of what we presently know about the fundamental interactions in nature has resulted from the study of two-body bound states. The hydrogen atom, the deuteron and positronium have provided valuable mechanisms for studying quantum mechanics, the theory of nuclear forces and QED. In the same way, one might hope that the study of two-body bound state systems built from heavy quarks will lead to a detailed understanding of at least some of the fundamental properties of strong interactions. While it is possible to gain some qualitative insights into strong interactions by studying bound states built from light quarks, it is not possible to reach more precise conclusions because of the additional complexities introduced by large relativistic corrections and long range confinement. Charmonium, c{anti c} bound states, has provided us with the first QCD laboratory where the system could be considered to be at least approximately non-relativistic while at the same time lending itself to perturbative calculations. The substantial mass of the charmed quark (m{sub c} {approximately} 1.5 GeV) corresponds to bound states sufficiently small to begin to probe the asymptotically free component of the strong interaction. The study of c{anti c} as well as b{anti b} bound states has greatly enhanced our understanding of the strong interaction between elementary particles. The scope of this article will be to review what has been learned to date, particularly on the experimental front, as well as to look at what remains to be done.

Search for low-Mass Higgs states @ BaBar

Several types of new-physics models predict the existence of light dark matter candidates and low-mass Higgs states. Previous \\babar searches for invisible light-Higgs decays have excluded large regions of model parameter space. We present searches for a dark-sector Higgs produced in association with a dark gauge boson and searches for a light Higgs in $\\Upsilon (nS)$ decays.

Qubits from tight knots and bent nano-bars  

E-Print Network (OSTI)

We propose a novel mechanism for creating a qubit based on a tight knot, that is a nano-quantum wire system so small and so cold as to be quantum coherent with respect to curvature-induced effects. To establish tight knots as legitimate candidates for qubits, we propose an effective curvature-induced potential that produces the two-level system and identify the tunnel coupling between the two local states. We propose also a different design of nano-mechanical qubit based on twisted nano-rods. We describe how both devices can be manipulated. Also we outline possible decoherence channels, detection schemes and experimental setups.

Searches for Leptonic B Decays at BaBar  

SciTech Connect

Measurements of the branching fractions of purely leptonic decays of B-mesons translate into constraints in the plane of the charged Higgs mass versus tan {beta} which are relatively insensitive to the particular theoretical model. Using the full BABAR dataset of 450 million B-decays we search for these decays. No significant signal is found in the decays into electrons or muons and we set upper limits on the branching fractions of the order of a 10{sup -6} at 90% confidence level. We measure the branching fraction of B {yields} {tau}{mu} to be (1.7 {+-} 0.6) x 10{sup -4}.

Recent Results in Semileptonic B Decays with BaBar  

SciTech Connect

In this note, recent results of studies of semileptonic B meson decays from BABAR are discussed and preliminary results given. In particular, a recent measurement of {Beta}(B {yields} D{sup (*)}{tau}{nu}) and the ratio {Beta}(B {yields} D{sup (*)}{tau}{nu})/{Beta}(B {yields} D{sup (*)}{ell}{nu}) is presented. For the D* mode, a branching fraction of 1.79 {+-} 0.13(stat) {+-} 0.17(syst) is found, with a ratio of 0.325 {+-} 0.023(stat) {+-} 0.027(syst). For the D mode, the results are 1.04 {+-} 0.12(stat) {+-} 0.14(syst) and 0.456 {+-} 0.053(stat) {+-} 0.056(syst), respectively. In addition, a study of B{sub s} production and semileptonic decays using data collected in a center-of-mass energy region above the {Upsilon}(4S) resonance is discussed. The semileptonic branching fraction {Beta}(B{sub s} {yields} {ell}{nu}X) is measured to be 9.9{sub -2.1}{sup +2.6}(stat){sub -2.0}{sup +1.3}(syst).

Indirect Charged Higgs Constraints from BaBar  

SciTech Connect

The high-statistics data samples from the BABAR and Belle B-Factory experiments provide stringent constraints on charged Higgs bosons within the context of specific New Physics models. These constraints are obtained by comparing Standard Model predictions with experimental observations in rare B decays with potential sensitivity to contributions mediated by a virtual H{sup {+-}} in tree or loop diagrams. Recent experimental results on the decays B{sup +} {yields} {mu}{sup +}{nu}, B{sup +} {yields} {tau}{sup +}{nu} and inclusive B {yields} X{sub s}{gamma} are described and the implications of these measurements for charged Higgs bosons is discussed.

Search for a Light Higgs Boson at BaBar  

Science Conference Proceedings (OSTI)

We search for evidence of a light Higgs boson (A{sup 0}) in the radiative decays of the narrow {Upsilon}(3S) resonance: {Upsilon}(3S) {yields} {gamma}A{sup 0}, where A{sup 0} {yields} invisible or A{sup 0} {yields} {mu}{sup +}{mu}{sup -}. Such an object appears in extensions of the Standard Model, where a light CP-odd Higgs boson naturally couples strongly to b-quarks. We find no evidence for such processes in a sample of 122 x 106 {Upsilon}(3S) decays collected by the BABAR collaboration at the PEP-II B-factory, and set 90% C.L. upper limits on the product of the branching fractions {Beta}({Upsilon}(3S) {yields} {gamma}A{sup 0}) x {Beta}(A{sup 0} {yields} invisible) at (0.7-31) x 10{sup -6} in the mass range mA{sup 0} {le} 7.8 GeV, and on the product {Beta}({Upsilon}(3S) {yields} {gamma}A{sup 0}) x {Beta}(A{sup 0} {yields} {mu}{sup +}{mu}{sup -}) at (0.25-5.2) x 10{sup -6} in the mass range 0.212 {le} mA{sup 0} {le} 9.3GeV. We also set a limit on the dimuon branching fraction of the recently discovered {eta}{sub b} meson {Beta}({eta}{sub b} {yields} {mu}{sup +}{mu}{sup -}) < 0.8% at 90% C.L. The results are preliminary.

Nuclear medium effects in $?(\\bar?)$-nucleus deep inelastic scattering  

E-Print Network (OSTI)

We study the nuclear medium effects in the weak structure functions $F_2(x,Q^2)$ and $F_3(x,Q^2)$ in the deep inelastic neutrino/antineutrino reactions in nuclei. We use a theoretical model for the nuclear spectral functions which incorporates the conventional nuclear effects, such as Fermi motion, binding and nucleon correlations. We also consider the pion and rho meson cloud contributions calculated from a microscopic model for meson-nucleus self-energies. The calculations have been performed using relativistic nuclear spectral functions which include nucleon correlations. Our results are compared with the experimental data of NuTeV and CDHSW.

In addition an investigation into the strange decay modes {tau}{sup -} {yields} K{sub S}{sup 0}{pi}{sup -}{pi}{sup 0}{nu}{sub {tau}} and {tau}{sup -} {yields} K{sub S}{sup 0}{pi}{sup -}{nu}{sub {tau}} is also presented, including a fit to the {tau}{sup -} {yields} K{sub S}{sup 0}{pi}{sup -}{nu}{sub {tau}} invariant mass spectrum.

A hard thermal loop benchmark for the extraction of the nonperturbative $Q\\bar{Q}$ potential  

E-Print Network (OSTI)

The extraction of the finite temperature heavy quark potential from lattice QCD relies on a spectral analysis of the Wilson loop. General arguments tell us that the lowest lying spectral peak encodes, through its position and shape, the real and imaginary part of this complex potential. Here we benchmark this extraction strategy using leading order hard-thermal loop (HTL) calculations. I.e. we analytically calculate the Wilson loop and determine the corresponding spectrum. By fitting its lowest lying peak we obtain the real- and imaginary part and confirm that the knowledge of the lowest peak alone is sufficient for obtaining the potential. Access to the full spectrum allows an investigation of spectral features that do not contribute to the potential but can pose a challenge to numerical attempts of an analytic continuation from imaginary time data. Differences in these contributions between the Wilson loop and gauge fixed Wilson line correlators are discussed. To better understand the difficulties in a numerical extraction we deploy the Maximum Entropy method with extended search space to HTL correlators in Euclidean time and observe how well the known spectral function and values for the real and imaginary part are reproduced. Possible venues for improvement of the extraction strategy are discussed.

Radial sensitivity of kaonic atoms and strongly bound $\\bar K$ states  

E-Print Network (OSTI)

The strength of the low energy K^- nucleus real potential has recently received renewed attention in view of experimental evidence for the possible existence of strongly bound K^- states. Previous fits to kaonic atom data led to either 'shallow' or to 'deep' potentials, where only the former are in agreement with chiral approaches but only the latter can produce strongly bound states. Here we explore the uncertainties of the K^- nucleus optical potentials, obtained from fits to kaonic atom data, using the functional derivatives of the best-fit chi^2 values with respect to the potential. We find that only the deep type of potential provides information which is applicable to the K^- interaction in the nuclear interior.

Failure Scenarios and Mitigations and for the BaBar Superconducting Solenoid  

Science Conference Proceedings (OSTI)

The cryogenic department at the Stanford Linear Accelerator Center is responsible for the operation, troubleshooting, and upgrade of the 1.5 Tesla superconducting solenoid detector for the BABAR B-factory experiment. Events that disable the detector are rare but significantly impact the availability of the detector for physics research. As a result, a number of systems and procedures have been developed over time to minimize the downtime of the detector, for example improved control systems, improved and automatic backup systems, and spares for all major components. Together they can prevent or mitigate many of the failures experienced by the utilities, mechanical systems, controls and instrumentation. In this paper we describe various failure scenarios, their effect on the detector, and the modifications made to mitigate the effects of the failure. As a result of these modifications the reliability of the detector has increased significantly with only 3 shutdowns of the detector due to cryogenics systems over the last 2 years.

Search for a Low-Mass Higgs Boson (A0) at BaBar  

Science Conference Proceedings (OSTI)

The BABAR Collaboration has performed three searches for a light Higgs boson, A{sup 0}, in radiative Upsilon ({Upsilon}) decays: {Upsilon}(3S) {yields} {gamma}A{sup 0}, A{sup 0} {yields} {tau}{sup +}{tau}{sup -}; {Upsilon}(nS) {yields} {gamma}A{sup 0}, A{sup 0} {yields} {mu}{sup +}{mu}{sup -} (n = 2,3); and {Upsilon}(3S) {yields} {gamma}A{sup 0}, A{sup 0} {yields} invisible. Such a Higgs boson (A{sup 0}) appears in the Next-to-Minimal Supersymmetric extensions of the Standard Model, where a light CP-odd Higgs boson couples strongly to b-quarks. The searches are based on data samples that consist of 122 x 10{sup 6} {Upsilon}(3S) and 99 x 10{sup 6} {Upsilon}(2S) decays, collected by the BABAR detector at the SLAC National Accelerator Laboratory. The searches reveal no evidence for an A{sup 0}, and product of branching fractions upper limits, at 90% C.L., of (1.5-16) x 10{sup -5}, (0.44-44) x 10{sup -6}, and (0.7-31) x 10{sup -6} were obtained for these searches, respectively. Also, we set the upper limits {Beta}({eta}{sub b} {yields} {tau}{sup +}{tau}{sup -}) < 8% and {Beta}({eta}{sub b} {yields} {mu}{sup +}{mu}{sup -}) < 0.9%.

Recent developments in Grid technologies could provide a way to manage the distributed resources in a single coherent structure. We describe enhancements to the BABAR experiment's distributed skimmed dataset production system to make use of European Grid resources and present the results with regard to BABAR's latest cycle of skimmed dataset production. We compare the benefits of a local and Grid-based systems, the ease with which the system is managed and the challenges of integrating the Grid with legacy software. We compare job success rates and manageability issues between Grid and non-Grid production.

Measurement of D0 lifetime with the BaBar detector  

SciTech Connect

This work is the result of the researchers carried out during a three years Ph.D. period in the BABAR experiment. The first chapter consists in an introduction to the theoretical aspects of the D{sup 0} meson lifetime determination and CP violation parameters, as well as an overview of the CP violation in the B sector, which is the main topic of the experiment. The description of the experimental apparatus follows with particular attention to the Silicon Vertex Tracker detector, the most critical detector for the determination of decay vertices and thus of lifetimes and time dependent CP violation asymmetries. In the fourth chapter the operation and running of the vertex detector is described, as a result from the experience as Operation Manager of the SVT, with particular attention to the safety of the device and the data quality assurance. The last chapter is dedicated to the determination of the D{sup 0} meson lifetime with the BABAR detector, which is the main data analysis carried out by the candidate. The analysis is characterized by the selection of an extremely pure sample of D{sup 0} mesons for which the decay flight length and proper time is reconstructed. The description of the unbinned maximum likelihood fit follows, as well as the discussion of the possible sources of systematic uncertainties. In the appendix is also presented a preliminary study of a possible development regarding the determination of mixing and CP violation parameters for the D{sup 0} meson.

Charmless Hadronic B Decays into Vector, Axial Vector and Tensor Final States at BaBar  

SciTech Connect

We present experimental measurements of branching fraction and longitudinal polarization fraction in charmless hadronic B decays into vector, axial vector and tensor final states with the final dataset of BABAR. Measurements of such kind of decays are a powerful tool both to test the Standard Model and search possible sources of new physics. In this document we present a short review of the last experimental results at BABAR concerning charmless quasi two-body decays in final states containing particles with spin 1 or spin 2 and different parities. This kind of decays has received considerable theoretical interest in the last few years and this particular attention has led to interesting experimental results at the current b-factories. In fact, the study of longitudinal polarization fraction f{sub L} in charmless B decays to vector vector (VV), vector axial-vector (VA) and axial-vector axial-vector (AA) mesons provides information on the underlying helicity structure of the decay mechanism. Naive helicity conservation arguments predict a dominant longitudinal polarization fraction f{sub L} {approx} 1 for both tree and penguin dominated decays and this pattern seems to be confirmed by tree-dominated B {yields} {rho}{rho} and B{sup +} {yields} {Omega}{rho}{sup +} decays. Other penguin dominated decays, instead, show a different behavior: the measured value of f{sub L} {approx} 0.5 in B {yields} {phi}K* decays is in contrast with naive Standard Model (SM) calculations. Several solutions have been proposed such as the introduction of non-factorizable terms and penguin-annihilation amplitudes, while other explanations invoke new physics. New modes have been investigated to shed more light on the problem.

Lepton Universality Test in Upsilon(1S) Decays at BaBar  

SciTech Connect

Using a sample of 122 million {Upsilon}(3S) decays collected with the BABAR detector at the PEP-II asymmetric energy collider at the SLAC National Accelerator Laboratory, we measure the ratio R{sub {tau}{mu}} = BR({Upsilon}(1S) {yields} {tau}{sup +}{tau}{sup -})/BR({Upsilon}(1S) {yields} {mu}{sup +}{mu}{sup -}); the measurement is intended as a test of lepton universality and as a possible search for a light pseudoscalar Higgs boson in Next to Minimal Supersymmetric Standard Model (NMSSM) scenarios. Such a boson could appear in a deviation of the ratio R{sub {tau}{mu}} from the Standard Model expectation, that is 1, except for small lepton mass corrections. The analysis exploits the decays {Upsilon}(3S) {yields} {Upsilon}(1S){pi}{sup +}{pi}{sup -}, {Upsilon}(1S) {yields} l{sup +}l{sup -}, where l = {mu},{tau}.

The Apache Point Observatory Galactic Evolution Experiment: First Detection of High Velocity Milky Way Bar Stars  

E-Print Network (OSTI)

Commissioning observations with the Apache Point Observatory Galactic Evolution Experiment (APOGEE), part of the Sloan Digital Sky Survey III, have produced radial velocities (RVs) for ~4700 K/M-giant stars in the Milky Way bulge. These high-resolution (R \\sim 22,500), high-S/N (>100 per resolution element), near-infrared (1.51-1.70 um; NIR) spectra provide accurate RVs (epsilon_v~0.2 km/s) for the sample of stars in 18 Galactic bulge fields spanning -1-32 deg. This represents the largest NIR high-resolution spectroscopic sample of giant stars ever assembled in this region of the Galaxy. A cold (sigma_v~30 km/s), high-velocity peak (V_GSR \\sim +200 km/s) is found to comprise a significant fraction (~10%) of stars in many of these fields.

Search for the Xi(2220) and Study of the X(3872) at BaBar  

SciTech Connect

The BABAR Collaboration performed a search for x (2220) production in the initial-state radiation process e{sup +}e{sup -} {yields} {gamma} J/{Psi}, J/{Psi} {yields} {gamma}K{sup +}K{sup -} or J/{Psi} {yields} {gamma}K{sub S}{sup 0}K{sub S}{sup 0}. No evidence for the {xi} (2220) resonance has been found. The 90% confidence level upper limits on the product of branching fractions are sensitive to the spin and helicity hypotheses. These upper limits are of the order 10{sup -5}, below the values reported in previous experiments. Also at BABAR, the decays B {yields} J/{Psi} {pi}{sup +}{pi}{sup -}{pi}{sup 0}K are studied to search for the decay X(3872) {yields} J/{Psi}{gamma}. This search yields a four standard deviation evidence for X(3872) {yields} J/{Psi}{omega}, with product branching fractions of {Beta}(B{sup +} {yields} X(3872)K{sup +}) x {Beta}(X(3872) {yields} J/{Psi}{omega}) = [0.6 {+-} 0.2(stat) {+-} 0.1(syst)] x 10{sup -5}, and {Beta}(B{sup 0} {yields} X(3872)K{sup 0}) x {Beta}(X(3872) {yields} J/y{Psi}) = [0.6 {+-} 0.3(stat) {+-} 0.1(syst)] x 10{sup -5}. A detailed study of the {pi}{sup +}{pi}{sup -}{pi}{sup 0} mass distribution from X(3872) decay favors a negative-parity assignment but does not rule out the positive-parity hypothesis.

Remote control and telescope auto-alignment system for multiangle LIDAR under development at CEILAP, Argentina  

E-Print Network (OSTI)

At CEILAP (CITEDEF-CONICET), a multiangle LIDAR is under development to monitor aerosol extinction coefficients in the frame of the CTA (Cherenkov Telescope Array) Project. This is an initiative to build the next generation of ground-based instruments to collect very high energy gamma-ray radiation (>10 GeV). The atmospheric conditions are very important for CTA observations, and LIDARs play an important role in the measurement of the aerosol optical depth at any direction. The LIDAR being developed at CEILAP was conceived to operate in harsh environmental conditions during the shifts, and these working conditions may produce misalignments. To minimize these effects, the telescopes comprising the reception unit are controlled by a self-alignment system. This paper describes the self-alignment method and hardware automation.

Forward-Backward Asymmetry at High Mass in $t\\bar{t}$ Production in $p\\bar{p}$ Collisions at $\\sqrt{s} = 1.96$ TeV  

SciTech Connect

Current understanding of particle physics postulates that there are 17 fundamental particles that interact via four fundamental forces - gravity, the strong force, the weak force, and the electromagnetic force. These fundamental particles can be classified by their spins into bosons, which are the force-carrying particles with integer spins, and fermions, which have half-integer spins. Fermions can be further divided into quarks and leptons. The particles and three of the four forces - all but gravity - are described by the Standard Model, a local SU(3) x SU(2) x U(1) gauge theory. Electromagnetic and weak interactions as described by Electroweak Theory or Quantum Electrodynamics, SU(2) x U(1). Strong interactions are described by Quantum Chromodynamics or QCD, SU(3). Fermions are grouped into three generations as shown in Table 1.1. Each generation consists of a leptonic doublet containing a charged and a neutral lepton and a weak isospin doublet containing two quarks. The first generation, containing the electron, the electron neutrino, the up quark, and the down quark, is the lightest generation and is thus the most frequently found in nature. The second generation contains the muon, the muon neutrino, the strange quark, and the charm quark. The third generation contains the tau, the tau neutrino, the bottom quark, and the top quark.

Science Conference Proceedings (OSTI)

The s-channel annihilation of a proton and an antiproton into a neutral pion and a real or virtual photon followed by lepton pair emission is studied. Such a mechanism is expected to play a role at moderate values of the total energy {radical}s, when the pion is emitted in the angular region around 90 Degree-Sign in the center-of-mass system. A fair comparison with the existing data is obtained taking scattering and annihilation channels into account. The cross section is calculated and numerical results are given in the kinematical range accessible in the PANDA experiment at FAIR.

Relative Humidity in Limited Streamer Tubes for Stanford Linear Accelerator Center's BaBar Detector  

SciTech Connect

The BABAR Detector at the Stanford Linear Accelerator Center studies the decay of B mesons created in e{sup +}e{sup -} collisions. The outermost layer of the detector, used to detect muons and neutral hadrons created during this process, is being upgraded from Resistive Plate Chambers (RPCs) to Limited Streamer Tubes (LSTs). The standard-size LST tube consists of eight cells, where a silver-plated wire runs down the center of each. A large potential difference is placed between the wires and ground. Gas flows through a series of modules connected with tubing, typically four. LSTs must be carefully tested before installation, as it will be extremely difficult to repair any damage once installed in the detector. In the testing process, the count rate in most modules showed was stable and consistent with cosmic ray rate over an approximately 500 V operating range between 5400 to 5900 V. The count in some modules, however, was shown to unexpectedly spike near the operation point. In general, the modules through which the gas first flows did not show this problem, but those further along the gas chain were much more likely to do so. The suggestion was that this spike was due to higher humidity in the modules furthest from the fresh, dry inflowing gas, and that the water molecules in more humid modules were adversely affecting the modules' performance. This project studied the effect of humidity in the modules, using a small capacitive humidity sensor (Honeywell). The sensor provided a humidity-dependent output voltage, as well as a temperature measurement from a thermistor. A full-size hygrometer (Panametrics) was used for testing and calibrating the Honeywell sensors. First the relative humidity of the air was measured. For the full calibration, a special gas-mixing setup was used, where relative humidity of the LST gas mixture could be varied from almost dry to almost fully saturated. With the sensor calibrated, a set of sensors was used to measure humidity vs. time in the LSTs. The sensors were placed in two sets of LST modules, one gas line flowing through each set. These modules were tested for count rate v. voltage while simultaneously measuring relative humidity in each module. One set produced expected readings, while the other showed the spike in count rate. The relative humidity in the two sets of modules looked very similar, but it rose significantly for modules further along the gas chain.

Extracting the Chern number from the dynamics of a Fermi gas: Implementing a quantum Hall bar for cold atoms  

E-Print Network (OSTI)

We propose a scheme to measure the quantized Hall conductivity of an ultracold Fermi gas initially prepared in a topological (Chern) insulating phase, and driven by a constant force. We show that the time evolution of the center of mass, after releasing the cloud, provides a direct and clear signature of the topologically invariant Chern number. We discuss the validity of this scheme, highlighting the importance of driving the system with a sufficiently strong force to displace the cloud over measurable distances while avoiding band-mixing effects. The unusual shapes of the driven atomic cloud are qualitatively discussed in terms of a semi-classical approach.

Study of the Ds+ to K+K-e+ nu Decay Channel with the BaBar Experiment  

SciTech Connect

Charm semileptonic decays allow a validation of lattice QCD calculations through the measurement of the hadronic form factors, which characterize the effect of strong interaction in these reactions. The accuracy of such calculations is crucial for the improvement of the test of the standard model in flavor physics. This thesis presents a study of the D{sub s}{sup +} {yields} K{sup +}K{sup -}e{sup +}{nu}{sub e} channel using 214 fb{sup -1} recorded by de BAbar experiment. For events with a K{sup +}K{sup -} mass in the range between 1.01 GeV/c{sup 2} and 1.03 Gev/c{sup 2}, the {phi} {yields} K{sup +}K{sup -} is the dominant component. Using the simple pole model to parameterize the q{sup 2} dependence of the form factors -V(q{sup 2}), A{sub 1}(q{sup 2}) and A{sub 2}(q{sup 2})- the following ratios are measured at q{sup 2} = 0; {tau}{sub V} = V(0)/A{sub 1}(0) = 1.868 {+-} 0.061 {+-} 0.079, r{sub 2} = A{sub 2}(0)/A{sub 1}(0) = 0.763 {+-} 0.072 {+-} 0.062. The mass pole of the axial-vector form factor is also obtained: m{sub A} = (2.30{sub -0.18}{sup +0.42} {+-} 0.21) GeV/c{sup 2}. In the same mass range, the semileptonic branching fraction, relative to the D{sub s}{sup +} {yields} {phi}{pi}{sup +} channel, is measured, and the absolute normalization of the axial-vector form factor is extracted: A{sub 1}(q{sup 2} = 0) and = 0.605 {+-} 0.012 {+-} 0.018 {+-} 0.018. The stated errors refer to the statistical, systematic and errors from external inputs, respectively. An S wave component in the K{sup +}K{sup -} system, possibly originating from a f{sub 0}, is also studied through its interference with the {phi}. An S wave component is observed for the first time in this decay channel with a 5{sigma} significance.

Measurement of the bottom quark cross section in [bar p]-p collisions using the exclusive decay B[sup 0] [yields] J/[psi]K[sup 0]*  

Science Conference Proceedings (OSTI)

A measurement of the b quark cross section in pp collisions is presented for b quarks with PT above 11.5 GeV/c and rapidity [parallel]y[parallel] < 1.0. The measurement is based on reconstruction of the exclusive decay B[sup o] [yields] J/[psi] K[sup o] in data taken with the CDF detector in the 1988-1989 Collider run. The measurement is compared to other CDF preliminary results and to theoretical predictions.

Measurement of ?_?and \\bar?_?induced neutral current single $?^0$ production cross sections on mineral oil at E_?O(1 GeV)  

E-Print Network (OSTI)

MiniBooNE reports the first absolute cross sections for neutral current single \\pi^0 production on CH_2 induced by neutrino and antineutrino interactions measured from the largest sets of NC \\pi^0 events collected to date. The principal result consists of differential cross sections measured as functions of \\pi^0 momentum and \\pi^0 angle averaged over the neutrino flux at MiniBooNE. We find total cross sections of (4.76+/-0.05_{stat}+/-0.76_{sys})*10^{-40} cm^2/nucleon at a mean energy of =808 MeV and (1.48+/-0.05_{stat}+/-0.23_{sys})*10^{-40} cm^2/nucleon at a mean energy of =664 MeV for \

Observation of a narrow mass state decaying into Upsilon(1S) + gamma in $p\\bar{p}$ collisions at sqrt(s) = 1.96 TeV  

Science Conference Proceedings (OSTI)

Using data corresponding to an integrated luminosity of 1.3 fb{sup -1}, we observe a narrow mass state decaying into {Upsilon}(1S) + {gamma}, where the {Upsilon}(1S) meson is detected by its decay into a pair of oppositely charged muons, and the photon is identified through its conversion into an electron-positron pair. The significance of this observation is 5.6 standard deviations. The mass of the state is centered at 10.551 {+-} 0.014(stat.) {+-} 0.017(syst.) GeV/c{sup 2}, which is consistent with that of the state recently observed by the ATLAS Collaboration.

Ba{anti B}ar status report on the design of a detector for the study of CP violation at PEP-II at SLAC  

SciTech Connect

Experiments designed to measure CP-violating asymmetries in the B meson system must emphasize exclusive state reconstruction with the highest possible resolution and efficiency. In the case of B{sup 0} mesons produced in pairs at the {Upsilon}(4S) resonance at an asymmetric e{sup +}e{sup {minus}} storage ring, this capability must be accompanied by precise vertex reconstruction in the direction of the e{sup +}e{sup {minus}} beams (henceforth the z direction). These are difficult requirements, beyond the scope of any existing storage ring detector. The challenge of designing an asymmetric storage ring capable of producing the large number of neutral B meson pairs required to measure CP-violating asymmetries in decays to CP eigenstates has been handsomely met in the PEP-II design. As the first asymmetric e{sup +}e{sup {minus}} storage ring, PEP-II presents a novel set of experimental challenges to a 4{pi} detector. This Status Report describes the design of a new detector fully capable of exploiting the physics opportunities provided by PEP-II.

An additional study of multi-muon events produced in $p\\bar{p}$ collisions at $\\sqrt{s}=1.96$ TeV  

Science Conference Proceedings (OSTI)

We present one additional study of multi-muon events produced at the Fermilab Tevatron collider and recorded by the CDF II detector. We use a data set acquired with a dedicated dimuon trigger and corresponding to an integrated luminosity of 3.9 fb{sup -1}. We investigate the distribution of the azimuthal angle between the two trigger muons in events containing at least four additional muon candidates to test the compatibility of these events with originating from known QCD processes. We find that this distribution is markedly different from what is expected from such QCD processes and this observation strongly disfavours the possibility that multi-muon events result from an underestimate of the rate of misidentified muons in ordinary QCD events.

How the Recent BaBar Data for P to Gamma Gamma* Affect the Standard Model Predictions for the Rare Decays P to L+ L-  

SciTech Connect

Measuring the lepton anomalous magnetic moments (g-2) and the rare decays of light pseudoscalar mesons into lepton pairs P {yields} l{sup +}l{sup -}, serve as important tests of the Standard Model. To reduce the theoretical uncertainty in the standard model predictions, the data on the charge and transition form factors of the light pseudoscalar mesons play a significant role. Recently, new data on the behavior of the transition form factors P {yields} {gamma}{gamma}* at large momentum transfer were supplied by the BABAR collaboration. There are several problems with the theoretical interpretation of these data: (1) An unexpectedly slow decrease of the pion transition form factor at high momenta, (2) the qualitative difference in the behavior of the pion form factor and the {eta} and {eta}' form factors at high momenta, (3) the inconsistency of the measured ratio of the {eta} and {eta}' form factors with the predicted one. We comment on the influence of the new BABAR data on the rare decay branchings.
