Whitney Cooperative Institute for Meteorological Satellite Studies University of Wisconsin-Madison Madison, Wisconsin Introduction The second Water Vapor Intensive Observation Period (WVIOP) was held at the Southern Great Plains (SGP) Central Facility (CF) from September 15 to October 5, 1997, almost exactly 1 year after the first. As with the first WVIOP, this year's activities have resulted in an improved ability to measure atmospheric water vapor. This paper presents an introduction to the goals and participants, and a sampling of significant findings of the 1997 WVIOP from the perspective of the WVIOP chief scientist. For more

The pi -> pi pi process in nuclei and the restoration of chiral symmetry  

E-Print Network (OSTI)

The results of an extensive campaign of measurements of the pi -> pi pi process in the nucleon and nuclei at intermediate energies are presented. The measurements were motivated by the study of strong pi pi correlations in nuclei. The analysis relies on the composite ratio C_{pi pi}^A, which accounts for the clear effect of the nuclear medium on the (pi pi) system. The comparison of the C_{pi pi}^A distributions for the (pi pi)_{I=J=0} and (pi pi)_{I=0,J=2} systems to the model predictions indicates that the C_{pi pi}^A behavior in proximity of the 2m_pi threshold is explainable through the partial restoration of chiral symmetry in nuclei.

Measurement of the Wrong-Sign Decay D0 -> K+ pi- pi+ pi-  

E-Print Network (OSTI)

A measurement of the rate for the "wrong-sign" decay D0 -> K+ pi- pi+ pi- relative to that for the "right-sign" decay D0 -> K- pi+ pi+ pi- is presented. Using 791 fb-1 of data collected with the Belle detector, we obtain a branching fraction ratio of R_WS = [0.324 +- 0.008 (stat) +- 0.007 (sys)]%. Multiplying this ratio by the world average value for the branching fraction B(D0 -> K- pi+ pi+ pi-) gives a branching fraction B(D0 -> K+ pi- pi+ pi-) = (2.61 +- 0.06 +0.09 -0.08) x 10-4.

Photoproduction of {pi}{pi} Pairs off {sup 7}Li  

Science Conference Proceedings (OSTI)

This paper reports on the quasi-free photoproduction of {pi}{sup 0}{pi}{sup 0} and {pi}{sup 0}{pi}{sup +/-} pairs from {sup 7}Li in view of the in-medium properties of hadrons. Measurements have been done using the CB/TAPS detector setup and the Glasgow photon tagging spectrometer for incident photon energies up to 820 MeV. At small invariant masses, an enhancement of the neutral invariant mass distributions is seen compared to the mixed charged channel and could be explained either by an in-medium modification of the {pi}{pi} interaction in the I = J = 0 channel or by effects related to the final state interactions.

Search for CP violation in the decay $D^+ \\to \\pi^-\\pi^+\\pi^+$  

E-Print Network (OSTI)

A search for CP violation in the phase space of the decay $D^+\\to\\pi^-\\pi^+\\pi^+$ is reported using $pp$ collision data, corresponding to an integrated luminosity of 1.0 fb$^{-1}$, collected by the LHCb experiment at a centre-of-mass energy of 7 TeV. The Dalitz plot distributions for $3.1\\times 10^6$ $D^+$ and $D^-$ candidates are compared with binned and unbinned model-independent techniques. No evidence for CP violation is found.

S-wave K- pi+ system in D+ ---> K- pi+ pi+ decays from Fermilab E791  

SciTech Connect

A new approach to the analysis of three body decays is presented. Model-independent results are obtained for the S-wave K{pi} amplitude as a function of K{pi} invariant mass. These are compared with results from K{sup -}{pi}{sup +} elastic scattering, and the prediction of the Watson theorem, that the phase behavior be the same below K{eta}' threshold, is tested. Contributions from I = 1/2 and I = 3/2 are not resolved in this study. If I = 1/2 dominates, however, the Watson theorem does not describe these data well.

$\\rho-\\omega-$Interference in $J/\\psi-$Decays and $\\rho\\to \\pi^+\\pi^-\\pi^0$ Decay  

E-Print Network (OSTI)

We study $\\rho-\\omega-$interference by analyzing $J/\\psi\\to \\pi^+\\pi^-\\pi^0\\pi^0$. PDG-2002 data on $J/\\psi$ decays into $PP$ and $PV$ ($P$ denotes pseudoscalar mesons; $V$, vector mesons) are used to fit a generic model which describes the $J/\\psi$ decays. From the fits, we obtain anomalously large branching ratio $Br(\\rho^0\\to \\pi^+\\pi^-\\pi^0)\\sim 10^{-3}-10^{-2}$. A theoretical analysis for it is also provided, and the prediction is in good agreement with the anomalously large $Br(\\rho^0\\to \\pi^+\\pi^-\\pi^0)$. By the fit, we also get the $\\eta-\\eta'-$mixing angle $\\theta=-19.68^o\\pm 1.49^o$ and the constituent quark mass ratio $m_u/m_s\\sim 0.6$ which are all reasonable.

Dalitz Plot Analysis of B- -> D+ pi- pi-  

SciTech Connect

The author reports on a Dalitz plot analysis of B{sup -} {yields} D{sup +}{pi}{sup -}{pi}{sup -} decays, based on a sample of about 383 million {Upsilon}(4S) {yields} B{bar B} decays collected with the BABAR detector at the PEP-II asymmetric-energy B Factory at SLAC. They find the total branching fraction of the three-body decay: {Beta}(B{sup -} {yields} D{sup +} {pi}{sup -}{pi}{sup -}) = (1.08 {+-} 0.01 {+-} 0.05) x 10{sup -3}. the masses and widths of D*{sub 2}{sup 0} and D*{sub 0}{sup 0}, the 2{sup +} and 0{sup +} c{bar u} P-wave states decaying to D{sup +}{pi}{sup -}, are measured: m{sub D*{sub 2}{sup 0}} = (2460.4 {+-} 1.2 {+-} 1.2 {+-} 1.9) MeV/c{sup 2}, {Lambda}{sub D*{sub 2}{sup 0}} = (41.8 {+-} 2.5 {+-} 2.1 {+-} 2.0) MeV, m{sub D*{sub 0}{sup 0}} = (2297 {+-} 8 {+-} 5 {+-} 19) MeV/c{sup 2} and {Lambda}{sub D*{sub 0}{sup 0}} = (273 {+-} 12 {+-} 17 {+-} 45) MeV. The stated errors reflect the statistical and systematic uncertainties, and the uncertainty related to the assumed composition of signal events and the theoretical model.

First Observation of the Cabibbo-suppressed Decays Xi+(c) ---> Sigma+ pi- pi+ and Xi+(c) ---> Sigma- pi+ pi+ and Measurement of their Branching Ratios  

Science Conference Proceedings (OSTI)

The authors report the first observation of two Cabibbo-suppressed decay modes, {Xi}{sub c}{sup +} {yields} {Sigma}{sup +}{pi}{sup -}{pi}{sup +} and {Xi}{sub c}{sup +} {yields} {Sigma}{sup -} {pi}{sup +}{pi}{sup +}. They observe 56 {+-} 13 over a background of 21, and 23 {+-} 7 over a background of 12 events, respectively, for the signals. The data were accumulated using the SELEX spectrometer during the 1996-1997 fixed target run at Fermilab, chiefly from a 600 GeV/c {Sigma}{sup -} beam. The branching ratios of the decays relative to the Cabibbo-favored {Xi}{sub c}{sup +} {yields} {Xi}{sup -}{pi}{sup +}{pi}{sup +} are measured to be B({Xi}{sub c}{sup +} {yields} {Sigma}{sup +}{pi}{sup -}{pi}{sup +})/B({xi}{sub c}{sup +} {yields} {Xi}{sup -} {pi}{sup +}{pi}{sup +}) = 0.50 {+-} 0.20, and B({Xi}{sub c}{sup +} {yields} {Sigma}{sup -}{pi}{sup +}{pi}{sup +})/B({Xi}{sub c}{sup +} {yields} {Xi}{sup -}{pi}{sup +}{pi}{sup +}) = 0.23 {+-} 0.11, respectively. They also report branching ratios for the same decay modes of the {Lambda}{sub c}{sup +} relative to {Lambda}{sub c}{sup +} {yields} pK{sup -}{pi}{sup +}.

Test of charge conjugation invariance in eta->pi0 e+e- and eta->pi+pi-pi0 decays  

E-Print Network (OSTI)

Charge conjugation C is one of the fundamental symmetries in nature which transforms particles into antiparticles. This symmetry was studied in weak interaction where it is fully violated, but it is poorly known in the strong and electromagnetic interactions. To this end, in this thesis we investigated eta->pi+pi-pi0 and eta->pi0 e+e- decays, which might violate charge conjugation symmetry. The violation of C symmetry in eta->pi+pi-pi0 process could manifest itself as an asymmetry between energy spectra of charged pions. The eta->pi0 e+e- decay is forbidden by C symmetry in the first order of electromagnetic interaction, with the branching ratio on a level of 10^-8. Therefore, observation of a larger branching ratio could indicate a mechanism involving first order electromagnetic interaction violating charge conjugation. Both decays were investigated by means of the WASA-at-COSY detector operating at the COSY synchrotron at the Forchungszentrum Julich in Germany. The eta meson was produced via pp->pp eta reaction at the proton beam momentum of 2.14GeV/c. In total around 5x10^7 eta mesons were collected. As a result of the analysis conducted in the framework of this thesis a Dalitz Plot distribution for the eta->pi+pi-pi0 decay was obtained. From this distribution we extracted asymmetry parameters sensitive to C symmetry violation for different isospin values of the final state and we have established that all are consistent with zero within the obtained accuracy. For the eta->pi0 e+e- decay we have not observe signal and thus we estimated an upper limit for the branching ratio. The established upper limit amounts to $BR(eta->pi0 e+e-)<3.7x10^-5 at the 90% confidence level. This result is more precise than previously obtained in other experiments.

A RESONANCE IN THE Lambda pi SYSTEM  

DOE Green Energy (OSTI)

The authors report a study of the reaction K{sup -} + p {yields} {Lambda}{sup 0} + {pi}{sup +} + {pi}{sup -} produced by 1.15 Gev/c K{sup -} mesons and observed in the Lawrence Radiation Laboratory's 15-in. hydrogen bubble chamber. A preliminary report of these results was presented at the 1960 Rochester Conference. The beam was purified by two velocity spectrometers. A hyperon/observed during the run and the preliminary cross sections for various K{sup -} reactions at 1.15 Bev/c have been reported previously. Reaction (1) was the first one selected for detailed study, because it appeared to take place with relatively large probability and because the event, a 2-prong interaction accompanied by a V, was easily identified. In a volume of the chamber sufficiently restricted so that the scanning efficiency was near 100%, 255 such events were found. These events were measured, and the track data supplied to a computer which tested each event for goodness of fit to various kinematic hypotheses. The possible reactions, the distribution of events, and the corresponding cross sections are given in Table I. An event was placed in a given category of Table I if the {chi}{sup 2} probability for the other hypotheses was < 1%. It appears likely that the majority of the events in group(e) are also reactions of type (I). This belief is based on the following arguments: (1) since the kinematics of a {Lambda} {pi}{pi} fit (four constraints) are more overdetermined than those of a {Sigma}{sup 0} {pi}{pi} fit(two constraints), it is relatively easy for a {Lambda} {pi}{pi} reaction to fit a {Sigma}{sup 0} {pi}{pi} reaction, but only very few {Sigma}{sup 0} configurations can fit the {Lambda} {pi}{pi} reactions. (2) The events of group(e) when treated as {Sigma}{sup 0} {pi}{pi} reactions give a {chi}{sup 2} distribution which is much worse than that obtained when they are treated as {Lambda} {pi}{pi} reactions.

pi N to Multi-pi N Scattering in the 1/N_c Expansion  

E-Print Network (OSTI)

We extend the 1/N_c meson-baryon scattering formalism to pi N to multi-pi N case. We first show that the leading-order large N_c processes proceed through resonant intermediate states (e.g., rho N or pi Delta). We find that the pole structure of baryon resonances can be uniquely identified by their (non)appearance in eta N or mixed partial-wave pi Delta final states.

The Search for Exotic Mesons in gamma p -> pi+pi+pi-n with CLAS at Jefferson Lab  

E-Print Network (OSTI)

The $\\pi_1(1600)$, a $J^{PC} = 1^{-+}$ exotic meson has been observed by experiments using pion beams. Theorists predict that photon beams could produce gluonic hybrid mesons, of which the $\\pi_1(1600)$ is a candidate, at enhanced levels relative to pion beams. The g12 rungroup at Jefferson Lab's CEBAF Large Acceptance Spectrometer (CLAS) has recently acquired a large photoproduction dataset, using a liquid hydrogen target and tagged photons from a 5.71 GeV electron beam. A partial-wave analysis of 502K $\\gamma p \\to \\pi^+\\pi^+\\pi^-n$ events selected from the g12 dataset has been performed, and preliminary fit results show strong evidence for well-known states such as the $a_1(1260)$, $a_2(1320)$, and $\\pi_2(1670)$. However, we observe no evidence for the production of the $\\pi_1(1600)$ in either the partial-wave intensities or the relative complex phase between the $1^{-+}$ and the $2^{-+}$ (corresponding to the $\\pi_2$) partial waves.

Search For the Rare Decay K(L) ---> pi0 pi0 gamma  

SciTech Connect

This thesis describes a search for the rare decay K{sub L} {yields} {pi}{sup 0}{pi}{sup 0}{gamma} using data from the KTeV experiment, using the topology K{sub L} {yields} {pi}{sup 0}{pi}{sub D}{sup 0}{gamma} (where {pi}{sub D}{sup 0} {yields} {gamma}e{sup +}e{sup -}). Due to Bose statistics and the real nature of the photon, the K{sub L} {yields} {pi}{sup 0}{pi}{sup 0}{gamma} decay can proceed at lowest order only by the Cp conserving direct emission of an E2 photon. The decay vanishes to O(p{sup 4}) in chiral perturbation theory and is a probe of the theory to the sixth order. The primary background to this decay consists of K{sub L} {yields} {pi}{sup 0}{pi}{sup 0}{pi}{sub D}{sup 0} events with one lost photon. The upper limit for the decay K{sub L} {yields} {pi}{sup 0}{pi}{sup 0}{gamma} presented in this thesis is 2.32 x 10{sup -7} at the 90% confidence level. This upper limit was derived from both 1997 and 1999 data, using a blind analysis.

The authors present a study of the decays B{sup {+-}} {yields} DK{sup {+-}} with D mesons reconstructed in the K{sup +}{pi}{sup -}{pi}{sup 0} or K{sup -}{pi}{sup +}{pi}{sup 0} final states, where D indicates a D{sup 0} or a {bar D}{sup 0} meson. Using a sample of 474 million B{bar B} pairs collected with the BABAR detector at the PEP-II asymmetric-energy e{sup +}e{sup -} collider at SLAC, they measure the ratios R{sup {+-}} {triple_bond} {Lambda}(B{sup {+-}}{yields}[K{sup {-+}}{pi}{sup {+-}}{pi}{sup 0}]{sub D}K{sup {+-}})/{Lambda}(B{sup {+-}}{yields}[K{sup {+-}}{pi}{sup {-+}}{pi}{sup 0}]{sub D}K{sup {+-}}). They obtain R{sup +} = (5{sub -10}{sup +12}(stat){sub -4}{sup +2}(syst)) x 10{sup -3} and R{sup -} = (12{sub -10}{sup +12}(stat){sub -5}{sup +3}(syst)) x 10{sup -3}, from which they extract the upper limits at 90% probability: R{sup +} < 23 x 10{sup -3} and R{sup -} < 29 x 10{sup -3}. Using these measurements, they obtain an upper limit for the ratio r{sub B} of the magnitudes of the b {yields} u and b {yields} c amplitudes r{sub B} < 0.13 at 90% probability.

The Search for Exotic Mesons in gammap-->pi+pi+pi?n with CLAS at Jefferson Lab  

DOE Green Energy (OSTI)

In addition to ordinary qq-bar pairs, quantum chromodynamics (QCD) permits many other possibilities in meson spectra, such as gluonic hybrids, glueballs, and tetraquarks. Experimental discovery and study of these exotic states provides insight on the nonperturbative regime of QCD. Over the past twenty years, some searches for exotic mesons have met with controversial results, especially those obtained in the three-pion system. Prior theoretical work indicates that in photoproduction one should find gluonic hybrids at significantly enhanced levels compared to that found in pion production. To that end, the CLAS g12 run was recently completed at Jefferson Lab, using a liquid hydrogen target and tagged photons from a 5.71 GeV electron beam. The CLAS experimental apparatus was modified to maximize forward acceptance for peripheral production of mesons. The resulting data contains the world's largest 3pi photoproduction dataset, with gammap-->pi+pi+pi?n events numbering in the millions. Early results describing the data quality, kinematics, and dysnamics will be shown.

This thesis describes a Dalitz plot analysis of B{sup 0} {yields} K{sup +}{pi}{sup -}{pi}{sup 0} decays. The data sample comprises 213 million {Upsilon}(4S) {yields} B{bar B} decays collected with the BABAR detector at the PEP-II asymmetric-energy B Factory at the Stanford Linear Accelerator Center in California (SLAC). Preliminary results are presented for measurements of the inclusive branching fraction, quasi-two-body fractions and CP-violating charge asymmetries for intermediate states including K*(892){sup +}{pi}{sup -} and {rho}(770){sup -}K{sup +}. Observations of B{sup 0} decays to the K{pi} S-wave intermediate states, K*{sub 0}(1430){sup +}{pi}{sup -} and K*{sub 0}(1430){sup 0}{pi}{sup 0}, are reported. Evidence of the decay B{sup 0} {yields} K*(892){sup 0}{pi}{sup 0} is seen. We set upper limits at 90% confidence level on branching fractions of the nonresonant and other less significant intermediate states.

ORKA: Measurement of the $K^ \\to \\pi^+ \  

Science Conference Proceedings (OSTI)

A high precision measurement of the ultra-rare K{sup +} {yields} {pi}{sup +} {nu}{bar {nu}} decay at Fermilab would be one of the most incisive probes of quark flavor physics this decade. Its dramatic reach for uncovering new physics is due to several important factors: (1) The branching ratio is sensitive to most new physics models which extend the Standard Model to solve its considerable problems. (2) The Standard Model predictions for the K{sup +} {yields} {pi}{sup +} {nu}{bar {nu}} and K{sub L}{sup 0} {yields} {pi}{sup 0} {nu}{bar {nu}} branching fractions are broadly recognized to be theoretically robust at the 5-10% level. Only a precious few accessible loop-dominated quark processes can be predicted with this level of certainty. (3) The K{sup +} {yields} {pi}{sup +} {nu}{bar {nu}} branching fraction is highly suppressed in the Standard Model to the level energy kaons. Recently, it has become evident that the Fermilab Main Injector (MI) accelerator, running at about 95 GeV with a moderate duty factor to produce kaons, presents an opportunity to extend this approach by two orders of magnitude in sensitivity. The first order of magnitude improvement comes from the substantially brighter source of low energy kaons, and the second arises from incremental improvements to the experimental techniques firmly established at BNL. The proposed experiment at Fermilab, ORKA, will yield a precision of 5% for the K{sup +} {yields} {pi}{sup +} {nu}{bar {nu}} branching ratio measurement, which is comparable to the uncertainty of the Standard Model prediction. Opportunities for further advances to attain even higher precision would be made possible by the advent of Project X.

CP violation in the D0 -> pi+ pi- decay at CDF  

SciTech Connect

We report a measurement of the CP violating asymmetry in D{sup 0} {yields} {pi}{sup +}{pi}{sup -} decays using approximately 215,000 decays reconstructed in about 5.94 fb{sup -1} of CDF data. We use the strong D*{sup +} {yields} D{sup 0}{pi}{sup +} decay ('D* tag') to identify the flavor of the charmed meson at production time and exploit CP-conserving strong c{bar c} pair-production in p{bar p} collisions. Higher statistic samples of Cabibbo-favored D{sup 0} {yields} K{sup -}{pi}{sup +} decays with and without D* tag are used to highly suppress systematic uncertainties due to detector effects. The result, A{sub CP}(D{sup 0} {yields} {pi}{sup +}{pi}{sup -}) = [0.22 {+-} 0.24 (stat.) {+-} 0.11 (syst.)]%, is the world's most precise measurement to date and it is fully consistent with no CP violation.

Strong D*{yields}D{pi} and B*{yields}B{pi} couplings  

SciTech Connect

We compute g{sub D}{sup *}{sub D{pi}} and g{sub B}{sup *}{sub B{pi}} using a framework in which all elements are constrained by Dyson-Schwinger equation studies of QCD and therefore incorporates a consistent, direct, and simultaneous description of light and heavy quarks and the states they may constitute. We link these couplings with the heavy-light-meson leptonic decay constants and thereby obtain g{sub D}{sup *}{sub D{pi}}=15.9{sub -1.0}{sup +2.1} and g{sub B}{sup *}{sub B{pi}}=30.0{sub -1.4}{sup +3.2}. From the latter, we infer g{sub B}=0.37{sub -0.02}{sup +0.04}. A comparison between g{sub D}{sup *}{sub D{pi}} and g{sub B}{sup *}{sub B{pi}} indicates that when the c quark is a system's heaviest constituent, {Lambda}{sub QCD}/m{sub c}-corrections are not under good control.

A high precision measurement of the ultra-rare K{sup +} {yields} {pi}{sup +} {nu}{bar {nu}} decay at Fermilab would be one of the most incisive probes of quark flavor physics this decade. Its dramatic reach for uncovering new physics is due to several important factors: (1) The branching ratio is sensitive to most new physics models which extend the Standard Model to solve its considerable problems. (2) The Standard Model predictions for the K{sup +} {yields} {pi}{sup +} {nu}{bar {nu}} and K{sub L}{sup 0} {yields} {pi}{sup 0} {nu}{bar {nu}} branching fractions are broadly recognized to be theoretically robust at the 5-10% level. Only a precious few accessible loop-dominated quark processes can be predicted with this level of certainty. (3) The K{sup +} {yields} {pi}{sup +} {nu}{bar {nu}} branching fraction is highly suppressed in the Standard Model to the level < 10{sup -10} (<1 part in 10 billion). This suppression allows physics beyond the Standard Model to contribute dramatically to the branching fraction with enhancements of up to factors of 5 above the Standard Model level. (4) The certainty with which the Standard Model contribution to K{sup +} {yields} {pi}{sup +} {nu}{bar {nu}} can be predicted will permit a 5{sigma} discovery potential for new physics even for enhancements of the branching fraction as small as 35%. This sensitivity is unique in quark flavor physics and allows probing of essentially all models of new physics that couple to quarks within the reach of the LHC. Furthermore, a high precision measurement of K{sup +} {yields} {pi}{sup +} {nu}{bar {nu}} is sensitive to many models of new physics with mass scales well beyond the direct reach of the LHC. The experimental challenge of suppressing backgrounds to enable measurement of K{sup +} {yields} {pi}{sup +} {nu}{bar {nu}} at the 1 in 10-billion Standard Model rate has been met successfully. Several events of K{sup +} {yields} {pi}{sup +} {nu}{bar {nu}} decay have been clearly observed at BNL by using a carefully refined technique involving stopped low-energy kaons. Recently, it has become evident that the Fermilab Main Injector (MI) accelerator, running at about 95 GeV with a moderate duty factor to produce kaons, presents an opportunity to extend this approach by two orders of magnitude in sensitivity. The first order of magnitude improvement comes from the substantially brighter source of low energy kaons, and the second arises from incremental improvements to the experimental techniques firmly established at BNL.

Dalitz Analysis of Ds -> K K- pi-  

Science Conference Proceedings (OSTI)

We perform a Dalitz plot analysis of about 100,000 D{sub s}{sup +} decays to K{sup +}K{sup -}{pi}{sup +} and measure the complex amplitudes of the intermediate resonances which contribute to this decay mode. We also measure the relative branching fractions of D{sub s}{sup +} {yields} K{sup +}K{sup +}{pi}{sup -} and D{sub s}{sup +} {yields} K{sup +}K{sup +}K{sup -}. For this analysis we use a 384 fb{sup -1} data sample, recorded by the BABAR detector at the PEP-II asymmetric-energy e{sup +}e{sup -} collider running at center-of-mass energies near 10.58 GeV.

Nuclear structure of {sup 10}B studied with (e,e{prime}), ({pi},{pi}{prime}) and ({gamma},{pi}) reactions  

SciTech Connect

The authors studied nuclear structure of {sup 10}B using (e,e{prime}),({pi},{pi}{prime}) and ({gamma},{pi}) reactions under the distorted wave impulse approximation (DWIA). For this purpose the off-shell dependence of the amplitude was taken into account in the momentum space DWIA. They used the off-shell elementary amplitude of ({pi},{pi}) and ({gamma},{pi}) by the model of Nozawa, Blankleider and Lee. The first order core polarization effects were incorporated with the p-shell wave functions of Cohen and Kurath and Hauge and Maripuu. It was shown that the core-polarization effects greatly improve the agreement with the experimental data and that the simultaneous study of these reactions is useful to probe the spin structure of p-shell nuclei.

Effect of Z Prime -mediated flavor-changing neutral current on B {yields} {pi}{pi} decays  

SciTech Connect

We study the effect of Z Prime -mediated flavor-changing neutral current on the B {yields} {pi}{pi} decays. The branching ratios of these decays can be enhanced remarkably in the nonuniversal Z Prime model. Our estimated branching ratios B(B{sup 0} {yields} {pi}{sup 0}{pi}{sup 0}) are enhanced significantly from their standard model (SM) value. For g Prime /g = 1, the branching ratios B(B{sup 0} {yields} {pi}{sup 0}{pi}{sup 0}) are very close to the recently observed experimental values and for higher values of g Prime /g branching ratios are more. Our calculated branching ratios B(B{sup 0} {yields} {pi}{sup +}{pi}{sup -}) and B(B{sup +} {yields} {pi}{sup +}{pi}{sup 0}) are also enhanced from the SM value as well as the recently observed experimental values. These enhancements of branching ratios from their SM value give the possibility of new physics.

Cross Sections for the Reactions e+e to K+ K- pi+pi-, K+ K- pi0pi0, and K+ K- K+ K- Measured Using Initial-State Radiation  

SciTech Connect

We study the processes e{sup +}e{sup -} {yields} K{sup +}K{sup -}{pi}{sup +}{pi}-{gamma}, K{sup +}K{sup -}{pi}{sup 0}{pi}{sup 0}{gamma}, and K{sup +}K{sup -}K{sup +}K{sup -}{gamma}, where the photon is radiated from the initial state. About 84000, 8000, and 4200 fully reconstructed events, respectively, are selected from 454 fb{sup -1} of BABAR data. The invariant mass of the hadronic final state defines the e{sup +}e{sup -} center-of-mass energy, so that the K{sup +}K{sup -}{pi}{sup +}{pi}{sup -}{gamma} data can be compared with direct measurements of the e{sup +}e{sup -} {yields} K{sup +}K{sup -}{pi}{sup +}{pi}{sup -} reaction. No direct measurements exist for the e{sup +}e{sup -} {yields} K{sup +}K{sup -}{pi}{sup 0}{pi}{sup 0} or e{sup +}e{sup -} {yields} K{sup +}K{sup -}K{sup +}K{sup -} reactions, and we present an update of our previous result with doubled statistics. Studying the structure of these events, we find contributions from a number of intermediate states, and extract their cross sections. In particular, we perform a more detailed study of the e{sup +}e{sup -} {yields} {phi}(1020){pi}{pi}{gamma} reaction, and confirm the presence of the Y (2175) resonance in the {phi}(1020)f{sub 0}(980) and K{sup +}K{sup -} f{sub 0}(980) modes. In the charmonium region, we observe the J/{psi} in all three final states and in several intermediate states, as well as the {phi}(2S) in some modes, and measure the corresponding branching fractions.

Observation and study of baryonic B decays: B -> D(*) p pbar, D(*) p pbar pi, and D(*) p pbar pi pi  

Science Conference Proceedings (OSTI)

We present a study of ten B-meson decays to a D{sup (*)}, a proton-antiproton pair, and a system of up to two pions using BABAR's data set of 455 x 10{sup 6} B{bar B} pairs. Four of the modes {bar B}{sup 0} {yields} D{sup 0}p{bar p}, {bar B}{sup 0} {yields} D*{sup 0}p{bar p}, {bar B}{sup 0} {yields} D{sup +}p{bar p}{pi}{sup -}, {bar B}{sup 0} {yields} D{sup ast+}p{bar p}{pi}{sup -} are studied with improved statistics compared to previous measurements; six of the modes (B{sup -} {yields} D{sup 0}p{bar p}{pi}{sup -}, B{sup -} {yields} D*{sup 0}p{bar p}{pi}{sup -}, {bar B}{sup 0} {yields} D{sup 0}p{bar p}{pi}{sup -}{pi}{sup +}, {bar B}{sup 0} {yields} D*{sup 0}p{bar p}{pi}{sup -}{pi}{sup +}, B{sup -} {yields} D{sup +}p{bar p}{pi}{sup -}{pi}{sup -}, B{sup -} {yields} D{sup ast+}p{bar p}{pi}{sup -}{pi}{sup -}) are first observations. The branching fractions for 3- and 5-body decays are suppressed compared to 4-body decays. Kinematic distributions for 3-body decays show non-overlapping threshold enhancements in m(p{bar p}) and m(D{sup (*)0}p) in the Dalitz plots. For 4-body decays, m(p{pi}{sup -}) mass projections show a narrow peak with mass and full width of (1497.4 {+-} 3.0 {+-} 0.9)MeV/c{sup 2} and (47 {+-} 12 {+-} 4)MeV/c{sup 2}, respectively, where the first (second) errors are statistical (systematic). For 5-body decays, mass projections are similar to phase space expectations. All results are preliminary.

Measurement of the CP Violation Parameters in B0 -> pi+ pi- Decays  

E-Print Network (OSTI)

We present a measurement of the time-dependent charge-parity (CP) violation parameters in B0 -> pi+ pi- decays. The results are obtained from the final data sample containing 772 million BBbar pairs collected at the Upsilon(4S) resonance with the Belle detector at the KEKB asymmetric-energy e+e- collider. We obtain the CP violation parameters Acp = +0.33 +/- 0.06 (stat) +/- 0.03 (syst) and Scp = -0.64 +/- 0.08 (stat) +/- 0.03 (syst), where Acp and Scp represent the direct and mixing-induced CP asymmetry, respectively. Using an isospin analysis including results from other Belle measurements, we find 23.8 < phi2 < 66.8 degrees is disfavored at the 1 sigma level, where phi2 is one of the three interior angles of the CKM unitarity triangle related to B_{u,d} decays.

Measurement of the tau- to eta pi-pi+pi-nu tau Branching Fraction and a Search for a Second-Class Current in the tau- to eta'(958)pi-nu tau Decay  

SciTech Connect

The {tau}{sup -} {yields} {eta}{pi}{sup -}{pi}{sup +}{pi}{sup -}{nu}{sub {tau}} decay with the {eta} {yields} {gamma}{gamma} mode is studied using 384 fb{sup -1} of data collected by the BABAR detector. The branching fraction is measured to be (1.60 {+-} 0.05 {+-} 0.11) x 10{sup -4}. It is found that {tau}{sup -} {yields} f{sub 1}(1285){pi}{sup -} {nu}{sub {tau}} {yields} {eta}{pi}{sup -}{pi}{sup +}{pi}{sup -}{nu}{sub {tau}} is the dominant decay mode with a branching fraction of (1.11 {+-} 0.06 {+-} 0.05) x 10{sup -4}. The first error on the branching fractions is statistical and the second systematic. In addition, a 90% confidence level upper limit on the branching fraction of the {tau}{sup -} {yields} {eta}{prime}(958){pi}{sup -}{nu}{sub {tau}} decay is measured to be 7.2 x 10{sup -6}. This last decay proceeds through a second-class current and is expected to be forbidden in the limit of isospin symmetry.

Observation of eta_c(1S) and eta_c(2S) decays to K K-pi pi-pi0 in two-photon interactions  

Science Conference Proceedings (OSTI)

We study the processes {gamma}{gamma} {yields} K{sub S}{sup 0}K{sup {+-}}{pi}{sup {-+}} and {gamma}{gamma} {yields} K{sup +}K{sup -}{pi}{sup +}{pi}{sup -}{pi}{sup 0} using a data sample of 519.2 fb{sup -1} recorded by the BABAR detector at the PEP-II asymmetric-energy e{sup +}e{sup -} collider at center-of-mass energies near the {Upsilon}(nS) (n = 2, 3, 4) resonances. We observe the {eta}{sub c}(1S), {chi}{sub c0}(1P), {chi}{sub c2}(1P), and {eta}{sub c}(2S) resonances produced in two-photon interactions and decaying to K{sup +}K{sup -}{pi}{sup +}{pi}{sup -}{pi}{sup 0}, with significances of 18.1, 5.7, 5.2, and 5.3 standard deviations (including systematic errors), respectively. We measure the {eta}{sub c}(2S) mass and width in K{sub S}{sup 0}K{sup {+-}}{pi}{sup {-+}} decays, m({eta}{sub c}(2S)) = 3638.5 {+-} 1.5 {+-} 0.8 MeV/c{sup 2} and {Lambda}({eta}{sub c}(2S)) = 13.4 {+-} 4.6 {+-} 3.2 MeV, where the first uncertainty is statistical and the second is systematic. We search for the Z(3930) resonance and find no significant signal. We also provide the two-photon width times branching fraction values for the observed resonances.

General results for the decays D {yields} {pi}{ell}{nu} and B {yields} {pi}{ell}{nu}  

SciTech Connect

Results are given for the two form factors for D {yields} {pi}{ell}{nu} and B {yields} {pi}{ell}{nu} at the soft pion limit. The deriviation depends only on pion PCAC and heavy quark spin symmetry. The usefulness of these results is discussed.

Observation and Study of the Baryonic B-meson Decays B to D(*) p pbar (pi) (pi)  

SciTech Connect

We present results for B-meson decay modes involving a charm meson, protons, and pions using 455 x 10{sup 6} B{bar B} pairs recorded by the BABAR detector at the SLAC PEP-II asymmetric-energy e{sup +}e{sup -} collider. The branching fractions are measured for the following ten decays: {bar B}{sup 0} {yields} D{sup 0}p{bar p}, {bar B}{sup 0} {yields} D*{sup 0}p{bar p}, {bar B}{sup 0} {yields} D{sup +}p{bar p}{pi}{sup -}, {bar B}{sup 0} {yields} D*{sup +}p{bar p}{pi}{sup -}, B{sup -} {yields} D{sup 0}p{bar p}{pi}{sup -}, B{sup -} {yields} D*{sup 0}pp{pi}{sup -}, {bar B}{sup 0} {yields} D{sup 0}p{bar p}{pi}{sup -}{pi}{sup +}, {bar B}{sup 0} {yields} D*{sup 0}p{bar p}{pi}{sup -}{pi}{sup +}, B{sup -} {yields} D{sup +}p{bar p}{pi}{sup -}{pi}{sup -}, and B{sup -} {yields} D*{sup +}p{bar p}{pi}{sup -}{pi}{sup -}. The four B{sup -} and the two five-body B{sup 0} modes are observed for the first time. The four-body modes are enhanced compared to the three- and the five-body modes. In the three-body modes, the M(p{bar p}) and M(D{sup (*)0}p) invariant mass distributions show enhancements near threshold values. In the four-body mode {bar B}{sup 0} {yields} D{sup +}p{bar p}{pi}{sup -}, the M(p{pi}{sup -}) distribution shows a narrow structure of unknown origin near 1.5GeV/c{sup 2}. The distributions for the five-body modes, in contrast to the others, are similar to the expectations from uniform phase-space predictions.

K+ -> pi+ mu+ mu- in E865 at BNL  

E-Print Network (OSTI)

Preliminary values for the K+ -> pi+ mu+ mu- branching ratio and form factor are reported, based on 400 events, a factor of 2 more in total events and 100 times the present world sample of fully reconstructed events. The results are consistent with previous results on the pi+ e+ e- mode. However, the relatively large slope of the form factor in q^2, lambda = 0.182+/-0.01+/-0.007, required to fit the pi+ e+ e- data and to give consistency between the pi+ e+ e- and pi+ mu+ mu- branching ratios, is larger than expected in simple models of the decays. The K+ -> pi+ mu+ mu- branching ratio we find, (9.23 +/- 0.6 stat +/- 0.58 syst)x10^-8, is the most precise measurement of this mode and is approximately 3.2 sigma larger than the previous measurement. These pi+ l+ l- results are inconsistent with O(p^4) Chiral Perturbation Theory but compatible with O(p^6). Systematic studies for both modes are still in progress.

Constraining gamma from K* pi and rho K Decays  

E-Print Network (OSTI)

We show that information on the weak phase gamma can be extracted from the K* pi and rho K decays. Less hadronic uncertainty is involved when the observables of four of these modes are combined together. We further point out two approximate relations in these decay modes can help determine whether there are new physics contributions in Delta I = 1 transitions, as hinted in the K pi modes.

Branching Ratio Measurements of B ---> J/psi eta K and B+- ---> D0 K+- with D0 ---> pi+ pi- pi0  

Science Conference Proceedings (OSTI)

Results are presented for the decays of B {yields} J/{psi}{eta}K and B{sup {+-}} {yields} DK{sup {+-}}, respectively, with experimental data collected with BABAR detector at PEP-II, located at Stanford Linear Accelerator Center (SLAC). With 90 x 10{sup 6} B{bar B} events at the {Upsilon}(4S) resonance, we obtained branching fractions of {Beta}(B{sup {+-}} {yields} J/{psi}{eta}K{sup {+-}}) = [10.8 {+-} 2.3(stat) {+-} 2.4(syst)] x 10{sup -5} and {Beta}(B{sup 0} {yields} J/{psi}{eta}K{sub S}{sup 0}) = [8.4 {+-} 2.6(stat) {+-} 2.7(syst)] x 10{sup -5}; and we set an upper limit of {Beta}[B{sup {+-}} {yields} X(3872)K{sup {+-}} {yields} J/{psi}{eta}K{sup {+-}}] < 7.7 x 10{sup -6} at 90% confidence level. The branching fraction of decay chain {Beta}(B{sup {+-}} {yields} DK{sup {+-}} {yields} {pi}{sup +}{pi}{sup -}{pi}{sup 0}K{sup {+-}}) = [5.5 {+-} 1.0(stat) {+-} 0.7(syst)] x 10{sup -6} with 229 x 10{sup 6} B{bar B} events at {Upsilon}(4S) resonance, here D represents the neutral D meson. The decay rate asymmetry is A = 0.02 {+-} 0.16(stat) {+-} 0.03(syst) for this full decay chain. This decay can be used to extract the unitarity angle {gamma}, a weak CP violation phase, through the interference of decay production of D{sup 0} and {bar D}{sup 0} to {pi}{sup +}{pi}{sup -}{pi}{sup 0}.

We measure the production cross sections for e{sup +}e{sup -}{yields}{Upsilon}(1S){pi}{sup +}{pi}{sup -}, {Upsilon}(2S){pi}{sup +}{pi}{sup -}, and {Upsilon}(3S){pi}{sup +}{pi}{sup -} as a function of {radical}(s) between 10.83 GeV and 11.02 GeV. The data consist of 8.1 fb{sup -1} collected with the Belle detector at the KEKB e{sup +}e{sup -} collider. We observe enhanced production in all three final states that does not agree well with the conventional {Upsilon}(10860) line shape. A fit using a Breit-Wigner resonance shape yields a peak mass of [10 888.4{sub -2.6}{sup +2.7}(stat){+-}1.2(syst)] MeV/c{sup 2} and a width of [30.7{sub -7.0}{sup +8.3}(stat){+-}3.1(syst)] MeV/c{sup 2}.

pi. pi. scattering by pole extrapolation methods. [2. 67 GeV/c, angular distribution, Chew-Low and Durr-Pilkum methods, OPE model, isospin  

SciTech Connect

A 25-inch hydrogen bubble chamber was used at the Lawrence Berkeley Laboratory Bevatron to produce 300,000 pictures of ..pi../sup +/p interactions at an incident momentum of the ..pi../sup +/ of 2.67 GeV/c. The 2-prong events were processed using the FSD and the FOG-CLOUDY-FAIR data reduction system. Events of the nature ..pi../sup +/p ..-->.. ..pi../sup +/p..pi../sup 0/ and ..pi../sup +/p ..-->.. ..pi../sup +/..pi../sup +/n with values of momentum transfer to the proton of -t less than or equal to 0.238 GeV/sup 2/ were selected. These events were used to extrapolate to the pion pole (t = m/sub ..pi..//sup 2/) in order to investigate the ..pi.. ..pi.. interaction with isospins of both T = 1 and T = 2. Two methods were used to do the extrapolation: the original Chew-Low method developed in 1959 and the Durr-Pilkuhn method developed in 1965 which takes into account centrifugal barrier penetration factors. At first it seemed that, while the Durr-Pilkuhn method gave better values for the total ..pi.. ..pi.. cross section, the Chew-Low method gave better values for the angular distribution. Further analysis, however, showed that if the requirement of total OPE (one-pion-exchange) were dropped, then the Durr-Pilkuhn method gave more reasonable values of the angular distribution as well as for the total ..pi.. ..pi.. cross section.

Concurrent $\\pi$-vector fields and energy beta-change  

E-Print Network (OSTI)

The aim of the present paper is to introduce and investigate intrinsically the notions of a concurrent $\\pi$-vector field and an energy beta-change on a Finsler manifold, using the pullback formalism. The effect of the existence of a concurrent $\\pi$-vector field on some important special Finsler spaces is studied. Under an energy beta-change, an intrinsic expression relating the the Barthel connection (resp. Cartan connection, Chern connection, Hashiguchi connection, Berwald connection) and the corresponding transformed connection is obtained. It should be pointed out that the present work is formulated in a prospective modern coordinate-free form.

Photoproduction of Baryons Decaying into N pi and N eta  

E-Print Network (OSTI)

A combined analysis of photoproduction data on \\gamma p to \\pi N, eta N was performed including the data on K Lambda and K Sigma. The data are interpreted in an isobar model with s--channel baryon resonances and pi, rho,(omega), K, and K^* exchange in the t--channel. Three baryon resonances have a substantial coupling to eta N, the well known N(1535)S_{11}, N(1720)P_{13}, and N(2070)D_{15}. The inclusion of data with open strangeness reveals the presence of further new resonances, N(1840)P_{11}, N(1875)D_{13} and N(2170)D_{13}.

Search for the Cryptoexotic Member of the Baryon Antidecuplet 1/2+ in the Reactions pi- p --> pi- p and pi- p --> K L  

E-Print Network (OSTI)

The main goal of this proposal is the search for a narrow cryptoexotic nucleon resonance by scanning of the pi- p system invariant mass in the region (1610-1770) MeV with the detection of pi- p and K Lambda decays. The scan is supposed to be done by the variation of the incident pi- momentum and its measurement with the accuracy of up to +-0.1% (better than 1 MeV in terms of the invariant mass in the whole energy range) with a set of proportional chambers located in the first focus of the magnetooptical channel. High sensitivity of the method to the resonance under search is shown. The secondary particles scattered from a liquid hydrogen target are detected by sets of the wire drift chambers equipped with modern electronics. The time scale of the project is about 3 years. The budget estimate including manpower, the apparatus and operation cost, is about 40 million rubles. The beam time required is (4-6) two week runs on "high" (10 GeV/c) flattop of the ITEP proton synchrotron.

D Pi scattering and D meson resonances from lattice QCD  

E-Print Network (OSTI)

The masses and widths of the broad scalar D_0^*(2400) and the axial D_1(2430) charmed-light resonances are extracted by simulating the corresponding D Pi and D* Pi scattering on the lattice. The resonance parameters are obtained using a Breit-Wigner fit of the elastic phase shifts. The resulting D_0^*(2400) mass is 351+/-21 MeV above the spin-average 1/4(m_D+3m_{D*}), in agreement with the experimental value of 347+/-29 MeV above. The resulting D_0^* to D Pi coupling g^{lat}=2.55+/-0.21 GeV is close to the experimental value g^{exp}simulation of the scattering in these channels incorporates quark-antiquark as well as multi-hadron interpolators, and the distillation method is used for contractions. In addition, the ground and several excited charm-light and charmonium states with various J^P are calculated using standard quark-antiquark interpolators. Our simulations are done in lattice QCD with two-dynamical light quarks at a mass corresponding to m_\\pi\\approx 266 MeV.

Measurements of indirect CP asymmetries in $D^0\\to K^-K^+$ and $D^0\\to\\pi^-\\pi^+$ decays  

E-Print Network (OSTI)

A study of indirect CP violation in $D^0$ mesons through the determination of the parameter $A_\\Gamma$ is presented using a data sample of $pp$ collisions, corresponding to an integrated luminosity of 1.0 fb$^{-1}$, collected with the LHCb detector and recorded at the centre-of-mass energy of 7 TeV at the LHC. The parameter $A_\\Gamma$ is the asymmetry of the effective lifetimes measured in decays of $D^0$ and $\\bar{D}^0$ mesons to the CP eigenstates $K^-K^+$ and $\\pi^-\\pi^+$. Fits to the data sample yield $A_\\Gamma(KK)=(-0.35\\pm0.62\\pm0.12)\\times 10^{-3}$ and $A_\\Gamma(\\pi\\pi)=(0.33\\pm1.06\\pm0.14)\\times 10^{-3}$, where the first uncertainties are statistical and the second systematic. The results represent the world's best measurements of these quantities. They show no difference in $A_\\Gamma$ between the two final states and no indication of CP violation.

The role of the N*(1535) resonance and the pi^- p --> KY amplitudes in the OZI forbidden pi N --> phi N reaction  

E-Print Network (OSTI)

We study the pi N --> phi N reaction close to the phi N threshold within the chiral unitary approach, by combining the pi^- p --> K^+ Sigma^-, pi^- p --> K^0 Sigma^0 and pi^- p --> K^0 Lambda amplitudes with the coupling of the phi to the K components of the final states of these reactions via quantum loops. We obtain a good agreement with experiment when the dominant pi^- p --> K^0 Lambda amplitude is constrained with its experimental cross section. We also evaluate the coupling of the N*(1535) to phi N and find a moderate coupling as a consequence of partial cancellation of the large KY components of the N*(1535). We also show that the N*(1535) pole approximation is too small to reproduce the measured cross section for the pi N --> phi N reaction.

pi+- p differential cross sections at low energies  

Science Conference Proceedings (OSTI)

Differential cross sections for pi- p and pi+ p elastic scattering were measured at five energies between 19.9 and 43.3 MeV. The use of the CHAOS magnetic spectrometer at TRIUMF, supplemented by a range telescope for muon background suppression, provided simultaneous coverage of a large part of the full angular range, thus allowing very precise relative cross section measurements. The absolute normalization was determined with a typical accuracy of 5 %. This was verified in a simultaneous measurement of muon proton elastic scattering. The measured cross sections show some deviations from phase shift analysis predictions, in particular at large angles and low energies. From the new data we determine the real part of the isospin forward scattering amplitude.

Further insights into the "$\\rho\\pi$ puzzle"  

E-Print Network (OSTI)

Based on a systematic investigation of $J/\\psi(\\psi^\\prime)\\to VP$, where $V$ and $P$ stand for light vector and pseudoscalar mesons, we identify the role played by the electromagnetic (EM) transitions and intermediate meson loop transitions, which are essential ingredients for understanding the $J/\\psi$ and $\\psi^\\prime$ couplings to $VP$. We show that on the one hand, the EM transitions have relatively larger interferences in $\\psi^\\prime\\to \\rho\\pi$ and $K^*\\bar{K}+c.c.$ as explicitly shown by vector meson dominance (VMD). On the other hand, the strong decay of $\\psi^\\prime$ receives relatively larger destructive interferences from the intermediate meson loop transitions. By identifying these mechanisms in an overall study of $J/\\psi(\\psi^\\prime)\\to VP$, we provide a coherent understanding of the so-called "$\\rho\\pi$ puzzle".

Remarks on N N -> N N pi beyond leading order

In recent years a two-scale expansion was established to study reactions of the type N N -> N N pi within chiral perturbation theory. Then the diagrams of some subclasses that are invariant under the choice of the pion field no longer appear at the same chiral order. In this letter we show that the proposed expansion still leads to well defined results. We also discuss the appropriate choice of the heavy baryon propagator.

A 4. pi. tracking TPC magnetic spectrometer for RHIC  

Science Conference Proceedings (OSTI)

The primary physics objective of the 4{pi} TPC magnetic spectrometer proposal is to search for the Quark-Gluon Plasma. In previous workshops we have discussed what the possible hadronic signatures of such a state of matter would be. Succinctly, the QGP is a direct prediction of non-perturbative QCD. Therefore the question of the existence of this new state of matter bears directly on the validity of non-perturbative QCD. However, since non-perturbative QCD has never been established, it is apparent that what may await us is a host of new phenomena that will go beyond the standard model.

PI-controlled bioreactor as a generalized Lienard system  

E-Print Network (OSTI)

It is shown that periodic orbits can occur in Cholette's bioreactor model working under the influence of a PI-controller. We find a diffeomorphic coordinate transformation that turns this controlled enzymatic reaction system into a generalized Lienard form. Furthermore, we give sufficient conditions for the existence and uniqueness of limit cycles in the new coordinates. We also perform numerical simulations illustrating the possibility of the existence of a local center (period annulus). A result with possible practical applications is that the oscillation frequency is a function of the integral control gain parameter

2nd Annual DOE-ERSP PI Meeting: Abstracts  

Science Conference Proceedings (OSTI)

Welcome to the annual 2007 Environmental Remediation Sciences Program (ERSP) Principal Investigators (PIs) meeting. The purpose of this meeting is to bring together all of the lead PIs and key Co-PIs in the program to share and review the results of funded research from the past year. This meeting allows program managers from the Environmental Remediation Sciences Division (ERSD) within the Office of Biological and Environmental Research (OBER) to gauge the progress and significance of the funded research, and it is also an important venue to showcase ERSP research to interested parties within DOE and other invited federal agency representatives. Additionally, these meetings should serve as an opportunity for funded PIs to view their research in the context of the entire ERSP portfolio. Past ERSP meetings have been very important venues for detailed discussion of research results among PIs, development of new research ideas, fostering new collaborations and discussion with ERSD program managers on future research efforts and/or initiatives within the program. In short, these meetings are an important resource for both program managers and PIs. There will be only one ERSP PI meeting for 2007. In years past, ERSD has sponsored two PI meetings, one in the spring and a separate meeting in the fall that focused primarily on field research. However, this format tends to insulate laboratory-based research from the field research sponsored in the program and is incompatible with the ERSD view that laboratory-based research should progress towards understanding the relevant processes in natural environments at the field scale. Therefore the agenda for this year's PI meeting is well integrated with both lab-based and field-based projects, to allow for detailed discussion between PIs involved in each area. In the agenda, you will notice a more relaxed format than in years past. This year's meeting spans four days, but is less heavily regimented in terms of oral presentations and allows ample time for informal group discussions and poster presentations. The intent of this format is to foster informal discussion of research among PIs and ERSD program managers-discussion that is a hallmark of previous ERSD-sponsored meetings. Morning sessions will be dominated by oral presentations from PIs chosen by ERSD program managers to communicate key topics of research within the program. There is ample time during lunch and in the early afternoon for small group discussions/meetings prior to convening again in the later afternoon for oral presentations on field research conducted at the Integrated Field-Scale Subsurface Research Challenge sites (IFCs). Formal poster sessions begin after dinner. Abstracts for all poster presentations are listed within this meeting booklet. On behalf of the ERSD program managers and staff, we thank you for attending this year's PI meeting. We look forward to discussing the results of your research with you and your ideas for the future, and we hope that this meeting will continue as an important tradition for PIs in the program and serve as a valuable resource for your investigations.

High rate 4. pi. beta. -. gamma. coincidence counting system  

SciTech Connect

A high count rate 4..pi.. ..beta..-..gamma.. coincidence counting system for the determination of absolute disintegration rates of short half-life radionuclides is described. With this system the dead time per pulse is minimized by not stretching any pulses beyond the width necessary to satisfy overlap coincidence requirements. The equations used to correct for the ..beta.., ..gamma.., and coincidence channel dead times and for accidental coincidences are presented but not rigorously developed. Experimental results are presented for a decaying source of /sup 56/Mn initially at 2 x 10/sup 6/ d/s and a set of /sup 60/Co sources of accurately known source strengths varying from 10/sup 3/ to 2 x 10/sup 6/ d/s. A check of the accidental coincidence equation for the case of two independent sources with varying source strengths is presented.

Helicity Asymmetry in gamma p -> pi+ n with FROST  

Science Conference Proceedings (OSTI)

The main objective of the FROST experiment at Jefferson Lab is the study of baryon resonances. The polarization observable E for the reaction gamma p to pi+n has been measured as part of this program. A circularly polarized tagged photon beam with energies from 0.35 to 2.35 GeV was incident on a longitudinally polarized frozen-spin butanol target. The final-state pions were detected with the CEBAF Large Acceptance Spectrometer. Preliminary polarization data agree fairly well with present SAID and MAID partial-wave analyses at low photon energies. In most of the covered energy range, however, significant deviations are observed. These discrepancies underline the crucial importance of polarization observables to further constrain these analyses.

4th Annual DOE-ERSP PI Meeting: Abstracts  

Science Conference Proceedings (OSTI)

This contains abstracts from the 2009 Annual Environmental Remediation Sciences Program (ERSP) Principal Investigators (PI) Meeting. The ERSP seeks to advance fundamental science to understand, predict, and mitigate the impacts of environmental contamination from past nuclear weapons production and provide a scientific basis for the long-term stewardship of nuclear waste disposal. These ambitious goals cannot be achieved by any one project alone. Therefore, ERSP funds a combination of research programs at the DOE national laboratories, individual projects at universities and federal agencies, and large long(er)-term field site research. Integration of these activities to advance the ERSP goals is a constant challenge, but made significantly simpler by bringing together all funded ERSP researchers once a year to discuss the very latest research results. It is at these meetings where new ideas and/or scientific advancements in support of ERSP goals can be discussed and openly debated among all PIs in the program. The ERSP thrives, in part, on the new ideas, concepts, scientific connections, and collaborations generated as a result of these meetings. The annual PI Meeting is very much a working meeting with three major goals: (1) to provide opportunities for scientific interaction among the ERSP scientists, a critical element for the program; (2) to provide the ERSP program staff with an opportunity to evaluate the progress of each program and project; and (3) to showcase the ERSP to interested parties within DOE and within other federal agencies In addition to program managers from within OBER, there will be representatives from other offices within DOE and other federal agencies in attandance at the meeting.

Measurement of CP--violating asymmetries in $D^0\\to\\pi^+\\pi^-$ and $D^0\\to K^+K^-$ decays at CDF  

SciTech Connect

We report on a measurement of CP-violating asymmetries (A{sub CP}) in the Cabibbo-suppressed D{sup 0} {yields} {pi}{sup +}{pi}{sup -} and D{sup 0} {yields} K{sup +}K{sup -} decays reconstructed in a data sample corresponding to 5.9 fb{sup -1} of integrated luminosity collected by the upgraded Collider Detector at Fermilab. We use the strong decay D*{sup +} {yields} D{sup 0}{pi}{sup +} to identify the flavor of the charmed meson at production and exploit CP-conserving strong c{bar c} pair-production in p{bar p} collisions. High-statistics samples of Cabibbo-favored D{sup 0} {yields} K{sup -}{pi}{sup +} decays with and without a D*{sup {+-}} tag are used to correct for instrumental effects and significantly reduce systematic uncertainties. We measure A{sub CP}(D{sup 0} {yields} {pi}{sup +}{pi}{sup -}) = (+0.22 {+-} 0.24(stat) {+-} 0.11 (syst))% and A{sub CP}(D{sup 0} {yields} K{sup +}K{sup -}) = (-0.24 {+-} 0.22 (stat) {+-} 0.09 (syst))%, in agreement with CP conservation. These are the most precise determinations from a single experiment to date. Under the assumption of negligible direct CP violation in D{sup 0} {yields} {pi}{sup +}{pi}{sup -} and D{sup 0} {yields} K{sup +}K{sup -} decays, the results provide an upper limit to the CP-violating asymmetry in D{sup 0} mixing, |A{sub CP}{sup ind}(D{sup 0})| < 0.13% at the 90% confidence level.

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.

4. pi. physics. [/sup 40/Ar + KCl, 0. 4 to 1. 8 GeV/A  

Science Conference Proceedings (OSTI)

Exclusive ..pi../sup -/ and charged-particle production in collisions of /sup 40/Ar on KCl are studied at incident energies from 0.4 to 1.8 GeV/A. The correlation between the ..pi../sup -/ and the total charged particle multiplicity confines the reaction along a narrow ridge with no exotic islands of pion production. For high multiplicities the system reaches the total disintegration of target and projectile into singly charged fragments and pions. Every 200 MeV/A datum was taken with a central and inelastic trigger. For central collisions the mean ..pi../sup -/ multiplicity increases linearly with the bombarding energy with no marked discontinuities due to the ..delta..(3,3) resonance. At 1.8 GeV/A evidence for nonthermal ..pi../sup -/ production in central collisions is found. The total c.m. energy in ..pi../sup -/ shows linear dependence on the ..pi../sup -/ multiplicity with a slope of epsilon = 300 MeV/..pi../sup -/. Strange particle production in the central collision of 1.8 GeV/A Ar on KCl is seen. 8 figures.

Relativistic three-body calculation of $pi$d scattering  

SciTech Connect

We present a unitary, Lorentz-invariant three-body calculation of pion- deuteron elastic scattering, based upon the idea of quasiparticle-dominated two- body interactions. We make detailed comparisons of these results with those of a conventional fixed-scatterer approach and find that the fixed-nucleon calculation does not adequately reproduce the three-body results; this finding demonstrates the importance of properly treating the three-body kinematics (i.e., of including nucleon recoil and isobar propagation). The multiple scattering expansion converges much more rapidly in the three-body approach than in the fixed- scatterer calculation. Intermediate nucleon-nucleon interactions play an important role, giving contributions to the scattering amplitude of the same order as those given by pion multiple scattering; these effects are especially significant for back-angle scattering. Finally, we compare our results with the available experimental data for the $pi$d total and integrated elastic cross sections and obtain good agreement. Nucleon spin is neglected in all calculations. (AIP)

Precise Measurement of the K - to Pi -E E- Decay  

SciTech Connect

A sample of 7253 K{sup {+-}} {yields} {pi}{sup {+-}}e{sup +}e{sup -}({gamma}) decay candidates with 1.0% background contamination has been collected by the NA 48/2 experiment at the CERN SPS, which allowed a precise measurement of the decay properties. The branching ratio in the full kinematic range was measured to be BR = (3.11 {+-} 0.12) x 10{sup -7}, where the uncertainty includes also the model dependence. The shape of the form factor W(z), where z = (M{sub ee}/M{sub K}){sup 2}, was parameterized according to several models, and, in particular, the slope {delta} of the linear form factor W(z) = W{sub 0}(1 + {delta}z) was determined to be {delta} = 2.32 {+-} 0.18. A possible CP violating asymmetry of K{sup +} and K{sup -} decay widths was investigated, and a conservative upper limit of 2.1 x 10{sup -2} at 90% CL was established.

2 pi-Steradian, Energetic-Ion Sensor  

E-Print Network (OSTI)

Because energetic particles populate both planetary magnetospheres and interplanetary space in significant quantities, energetic-ion sensors have been flown since the beginning of the space age. Early sensors were solid-state detector (SSD) telescopes, with conical fields of view, often swept through a circle by virtue of the spin motion of the spacecraft (e.g., IMP 7 and 8, ISEE 1 and 2). In the 1980s and 1990s, foil/microchannel plate (MCP) time-of-flight (TOF) measurements were added to the energy measurement provided by the SSD (eg, AMPTE/CCE MEPA, Geotail EPIC/ICS, Galileo EPD). The resulting energy and velocity uniquely identified ion mass. More recently, we have developed a 2-D fan acceptance angle sensor that includes both energy and TOF. When mounted on a spinning spacecraft, this 160^\\circ x 12^\\circ FOV sweeps out nearly 4\\pi steradians in one spin. This sensor, dubbed the "hockey puck" for its shape, is currently in flight on MESSENGER (EPS) and New Horizons Pluto (PEPPSI).Increasingly, energetic-...

Measurement of the difference of CP--violating asymmetries in $D^0 \\to K^+K^-$ and $D^0 \\to \\pi^+\\pi^-$ decays at CDF  

Science Conference Proceedings (OSTI)

We report a measurement of the difference (D/Acp) between time-integrated-violating asymmetries in D{sup 0} K{sup +}K{sup -} and D{sup 0} {pi}{sup +}{pi}{sup -} decays reconstructed in the full data set of proton-antiproton collisions collected by the Collider Detector at Fermilab, corresponding to 9.7 fb{sup -1} of integrated luminosity. The strong decay D*{sup +} D{sup 0}{pi}{sup +} is used to identify the charm meson at production as D{sup 0} or ['D]{sup 0}. We measure D/Acp = (-0.62 0.21 /stat 0.10 /syst)%, which differs from zero by 2.7 Gaussian standard deviations. This result supports similar evidence for violation in charm-quark obtained in proton-proton collisions.

Effects of light scalar mesons in $\\eta \\to 3\\pi$ decay  

E-Print Network (OSTI)

We study the role of a possible nonet of light scalar mesons in the still interesting $\\eta \\to 3\\pi$ decay process, with the primary motivation of learning more about the scalars themselves. The framework is a conventional non-linear chiral Lagrangian of pseudoscalars and vectors, extended to include the scalars. The parameters involving the scalars were previously obtained to fit the s-wave $\\pi\\pi$ and $\\pi$K scatterings in the region up to about 1 GeV as well as the strong decay $\\eta' \\to \\eta \\pi\\pi$. At first, one might expect a large enhancement from diagrams including a light $\\sigma(560)$. However there is an amusing cancellation mechanism which prevents this from occurring. In the simplest model there is an enhancement of about 13 per cent in the \\e3p decay rate due to the scalars. In a more complicated model which includes derivative type symmetry breakers, the cancellation is modified and the scalars contribute about 30 percent of the total decay rate (although the total is not significantly chan...

Benchmarks for the New-Physics Search through CP Violation in B^0->pi^0 K_S  

E-Print Network (OSTI)

Using isospin relations, we predict the Standard-Model correlation between S_{pi^0 K_S}=(sin 2beta)_{pi^0 K_S} and A_{pi^0 K_S}, the mixing-induced and direct CP asymmetries of B^0-> pi^0 K_S. The calculation uses flavour SU(3) only to fix the isospin-3/2 amplitude through the B^\\pm->pi^\\pm pi^0 branching ratio, and thus has a small irreducible theoretical error. It can reach percent level precision thanks to expected future lattice-QCD progress for the calculation of the relevant SU(3)-breaking form-factor ratio, and serves as a benchmark for new-physics searches. We obtain an interesting picture in the A_{pi^0 K_S} - S_{pi^0 K_S} plane, where the current experimental data show a discrepancy with the Standard Model, and comment on the direct CP asymmetries of B^0->pi^-K^+ and B^+ -> pi^0 K^+. A modified electroweak penguin with a large new CP-violating phase can explain the discrepancy and allows us to accommodate also the corresponding data for other b->s penguin-dominated decays.

{pi}-superconducting quantum interference device from ultracold fermionic atomic gases  

Science Conference Proceedings (OSTI)

Ultracold fermionic atomic gas with Bardeen-Cooper-Schrieffer pairing between hyperfine states is studied. It is shown that a {pi}-Josephson contact [superfluid-normal-gas-superfluid (S/N/S)] can be realized in systems where the left and right banks S are superfluids and the weak link N is a normal gas with the finite mismatch in chemical potentials {delta}{sub {mu}{sub N}}{ne}0. If such a {pi}-junction is part of a closed superfluid ring the superfluid mass-current flows spontaneously--the ultracold atomic {pi}-superconducting quantum interference device ({pi}-SQUID). This situation is realized if the radius of the ring R is larger than the critical one R{sub c}. The same effect will be realized also for {delta}{sub {mu}{sub N}}>>{delta}, where {delta} is the superfluid gap in S. The sensitivity of the {pi}-SQUID to inertial effects is discussed in the case of rotational motion.

Beam asymmetry for pi+ and pi0 photoproduction on the proton for photon energies from 1.102 to 1.862 GeV  

E-Print Network (OSTI)

Beam asymmetries for the reactions gamma p -> p pi0 and gamma p -> n pi+ have been measured with the CEBAF Large Acceptance Spectrometer (CLAS) and a tagged, linearly polarized photon beam with energies from 1.102 to 1.862 GeV. A Fourier moment technique for extracting beam asymmetries from experimental data is described. The results reported here possess greater precision and finer energy resolution than previous measurements. Our data for both pion reactions appear to favor the SAID and Bonn-Gatchina scattering analyses over the older Mainz MAID predictions. After incorporating the present set of beam asymmetries into the world database, exploratory fits made with the SAID analysis indicate that the largest changes from previous fits are for properties of the Delta(1700) 3/2- and Delta(1905) 5/2+ states.

ORKA, The Golden Kaon Experiment: Precision measurement of K+ -> pi+nunubar and other rare processes  

E-Print Network (OSTI)

ORKA is a proposed experiment to measure the K+ -> pi+nunubar branching ratio with 5% precision using the Fermilab Main Injector high-intensity proton source. The detector design is based on the BNL E787/E949 experiments, which detected seven K+ -> pi+nunubar candidate events. ORKA is expected to acheive two orders of magnitude improvement in sensitivity relative to the BNL experiments as a result of enhancements to the beam line and the detector acceptance. Precise measurement of the K+ -> pi+nunubar branching ratio with the same level of uncertainty as the well-understood Standard Model prediction allows for sensitivity to new physics at and beyond the LHC mass scale. Detector R&D, simulation-based optimization of the experiment design, and preparation of the experiment location are underway.

Search for Theta+ via pi- p --> K- X reaction near production threshold  

E-Print Network (OSTI)

We have searched for $\\Theta^{+}$ via $\\pi^{-}p \\to K^{-}X$ reaction using 1.87 and 1.92 GeV/c $\\pi^{-}$ beam at the K2 beam line of the KEK 12 GeV Proton Synchrotron. In the missing mass spectrum at beam momentum of 1.92 GeV/$c$, a bump has been found at 1530 MeV/$c^{2}$ which is consistent with the mass reported by several experiments. The statistical significance of this bump, however, is only 2.5$-2.7\\sigma$. Therefore we have derived the upper limit of $\\Theta^{+}$ production cross section via $\\pi^{-}p \\to K^{-}\\Theta^{+}$ reaction which is 4.3$\\mu$b at 90% confidence level assuming that $\\Theta^{+}$ is produced isotropically in the center of mass system.

Doping Dependence of the $(\\pi,\\pi)$ Shadow Band in La-Based Cuprates Studied by Angle-Resolved Photoemission Spectroscopy  

SciTech Connect

The ({pi},{pi}) shadow band (SB) in La-based cuprate family (La214) was studied by angle-resolved photoemission spectroscopy (ARPES) over a wide doping range from x = 0.01 to x = 0.25. Unlike the well-studied case of the Bi-based cuprate family, an overall strong, monotonic doping dependence of the SB intensity at the Fermi level (E{sub F}) was observed. In contrast to a previous report for the presence of the SB only close to x = 1/8, we found it exists in a wide doping range, associated with a doping-independent ({pi},{pi}) wave vector but strongly doping-dependent intensity: It is the strongest at x {approx} 0.03 and systematically diminishes as the doping increases until it becomes negligible in the overdoped regime. This SB with the observed doping dependence of intensity can in principle be caused by the antiferromagnetic fluctuations or a particular form of low-temperature orthorhombic lattice distortion known to persist up to x {approx} 0.21 in the system, with both being weakened with increasing doping. However, a detailed binding energy dependent analysis of the SB at x = 0.07 does not appear to support the former interpretation, leaving the latter as a more plausible candidate, despite a challenge in quantitatively linking the doping dependences of the SB intensity and the magnitude of the lattice distortion. Our finding highlights the necessity of a careful and global consideration of the inherent structural complications for correctly understanding the cuprate Fermiology and its microscopic implication.

The Search for the CP-violating emission of an E1 photon from the K(L) ---> pi+ pi- gamma decay  

SciTech Connect

A search for the CP-violating electric dipole (E1) direct emission contribution to the K{sub L} {yields} {pi}{sup +}{pi}{sup -}{gamma} decay is performed using data from the 1997 KTeV/E832 experiment. Because the K{sub L} {yields} {pi}{sup +}{pi}{sup -}{gamma} decay mode is massively dominated by the CP-violating inner bremsstrahlung (IB) and the CP-conserving magnetic dipole (M1) direct emission processes, previous analyses have neglected the E1 contribution. Therefore, this measurement is the first attempt to directly quantify the size of the E1 decay process. This E1 transition is one of the very few CP-violating processes that is accessible to experiment and, in principle, will produce new insights into the structure of the neutral kaon. The result of this analysis is that the E1 contribution is below the threshold of sensitivity, and therefore an upper bound of |g{sub E1}| < 0.14 (90% CL) is reported. In the process of obtaining this upper limit, high resolution measurements of fit parameters ({tilde g}{sub M1} and a{sub 1}/a{sub 2}) associated with the size and shape of the M1 direct emission peak are also extracted. The fit results for these parameters: {tilde g}{sub M1} = 1.229 {+-} 0.035 (stat) {+-} 0.087 (syst); a{sub 1}/a{sub 2} = -0.733 {+-} 0.007 (stat) {+-} 0.014 (syst) are in strong agreement with previous measurements.

Comparative evaluation of neural-network-based and PI current controllers for HVDC transmission  

Science Conference Proceedings (OSTI)

An investigation into a neural network (NN)-based controller, composed of a NN trained off-line in parallel with a NN trained on-line, is described in this paper. This NN controller has the potential of replacing the PI controller traditionally used for HVDC transmission systems. A theoretical basis for the operational behavior of the individual NN controllers is presented. Comparisons between the responses obtained with the NN and PI controllers for the rectifier of an HVDC transmission system are made under typical system perturbations and faults.

SciTech Connect

The hyperfine structure (hfs) of the A /sup 2/Pi excited state of Ca/sup 35/Cl has been investigated by using the new rf-pumped, laser-rf double-resonance technique. The optical unresolved hfs components of the R/sub 2/ (N'' = 101), Abold-arrow-left-rightX (0,0) line were resolved by double resonance, and the measured splittings, when combined with the known X /sup 2/..sigma../sup +/-state hfs spacings, show that the A /sup 2/Pi-state hfs splittings are not more than 1 MHz.

Structure of Lambda(1405) and threshold behavior of pi Sigma scattering  

SciTech Connect

The scattering length and effective range of the pi-Sigma channel are studied in order to characterize the strangeness S = -1 meson-baryon scattering and the Lambda (1405) resonance. We examine various off-shell dependence of the amplitude in dynamical chiral models to evaluate the threshold quantities with the constraint at the KN threshold. We find that the pi-Sigma threshold parameters are important to the structure of the Lambda (1405) resonance and provide further constraints on the subthreshold extrapolation of the KN interaction.

Measurement of branching fractions of B decays to K1(1270)pi and K1(1400)pi and determination of the CKM angle alpha from B0 --> a1(1260) - pi-  

SciTech Connect

In the Standard Model, CP violation in weak interactions involving quarks is parameterized by an irreducible complex phase in the Cabibbo-Kobayashi-Maskawa (CKM) quark-mixing-matrix. The precise determination of the CKM elements is a necessary ingredient for a stringent test of the Standard Model predictions, and is a crucial input for reducing the theoretical error in many New Physics searches with flavor, e.g., in the kaon sector. The unitarity of the CKM matrix is typically expressed as a triangle relationship among its parameters, where the area of the so-called Unitarity Triangle visually depicts the amount of asymmetry between the decays of B particles and their antimatter counterparts. In the past few years, the BABAR and Belle experiments have been able to measure all three angles of the triangle from CP asymmetry measurements. The first asymmetry measurements in B particle decays, about ten years ago, allowed to determine {beta}, which is now known to better than 5% precision. The angles {alpha} and {gamma}, measured in much rarer processes, required several years of data taking before analyses could yield reliable answers. A remarkable feature is that the direct measurement of the angles of the Unitarity Triangle generates an area that is consistent with the area predicted by measurement of the sides. In this thesis we have presented the branching fraction measurements of charged and neutral B meson decays to K{sub 1}(1270){pi} and K{sub 1}(1400){pi}, obtained from a data sample of 454 million {Upsilon}(4S) {yields} B{bar B} events. This analysis is particularly challenging from the experimental side since the branching fractions involved are very low, at the level of 10{sup -6} - 10{sup -7}, and the signal is characterized by the simultaneous presence of two overlapping resonances, which exhibit sizeable interference effects. The combined K{sub 1}(1270){pi} and K{sub 1}(1400){pi} signal is therefore modeled with a K-matrix formalism, which accounts for the effects of interference between the K{sub 1}(1270) and K{sub 1}(1400) mesons by introducing two effective parameters. The model is derived from the analysis, performed by the ACCMOR Collaboration, of the diffractive production of strange mesons.

K pi scattering for isospin 1/2 and 3/2 in lattice QCD

We extract the elastic phase shifts delta at several values of the K-pi relative momenta. The resulting phases exhibit qualitative agreement with the experimental phases in all four channels. We express the s-wave phase shifts near threshold in terms of the scattering length and the effective range. Our K pi system has zero total momentum and is simulated on a single ensemble with two dynamical quarks, so results apply for mpi=266 MeV and mK=552 MeV in our simulation. The backtracking contractions in both I=1/2 channels are handled by the use of Laplacian-Heavyside smeared quarks within the distillation method.

Search for the Z_1(4050)^+ and Z_2(4250)^+ States in bar B^0 to chi_{c1} K^- pi^+ and B^+ to chi_{c1} K^0_S pi^+  

SciTech Connect

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.

Analysis of the D+ --> K- pi+ e+ nu_e decay channel  

SciTech Connect

Using 347.5 fb{sup -1} of data recorded by the BABAR detector at the PEP-II electron-positron collider, 244 x 10{sup 3} signal events for the D{sup +} {yields} K{sup -}{pi}{sup +}e{sup +}{nu}{sub e} decay channel are analyzed. This decay mode is dominated by the {bar K}*(892){sup 0} contribution. We determine the {bar K}*(892){sup 0} parameters: m{sub K*(892){sup 0}} = (895.4{+-}0.2{+-}0.2) MeV/c{sup 2}, {Lambda}{sub K*(892){sup 0}}{sup 0} = (46.5{+-}0.3{+-}0.2) MeV/c{sup 2} and the Blatt-Weisskopf parameter r{sub BW} = 2.1{+-}0.5{+-}0.5 (GeV/c){sup -1} where the first uncertainty comes from statistics and the second from systematic uncertainties. We also measure the parameters defining the corresponding hadronic form factors at q{sup 2} = 0 (r{sub V} = V(0)/A{sub 1}(0) = 1.463{+-}0.017{+-}0.031, r{sup 2} = A{sub 2}(0)/A{sub 1}(0) = 0.801{+-}0.020{+-}0.020) and the value of the axial-vector pole mass parameterizing the q{sup 2} variation of A{sub 1} and A{sub 2}: m{sub A} = (2.63{+-}0.10{+-}0.13) GeV/c{sup 2}. The S-wave fraction is equal to (5.79{+-}0.16{+-}0.15)%. Other signal components correspond to fractions below 1%. Using the D{sup +} {yields} K{sup -}{pi}{sup +}{pi}{sup +} channel as a normalization, we measure the D{sup +} semileptonic branching fraction: {Beta}(D{sup +} {yields} K{sup -}{pi}{sup +}e{sup +}{nu}{sub e}) = (4.00 {+-} 0.03 {+-} 0.04 {+-} 0.09) x 10{sup -2} where the third uncertainty comes from external inputs. We then obtain the value of the hadronic form factor A{sub 1} at q{sup 2} = 0: A{sub 1}(0) = 0.6200 {+-} 0.0056 {+-} 0.0065 {+-} 0.0071. Fixing the P-wave parameters we measure the phase of the S-wave for several values of the K{pi} mass. These results confirm those obtained with K{pi} production at small momentum transfer in fixed target experiments.

Dynamical Coupled-Channel Model of pi-N scattering in te W < 2 GeV Nucleon Resonane Region  

SciTech Connect

As a first step to analyze the electromagnetic meson production reactions in the nucleon resonance region, the parameters of the hadronic interactions of a dynamical coupled-channel model, developed in {\\it Physics Reports 439, 193 (2007)}, are determined by fitting the empirical $\\pi N$ elastic scattering amplitudes of SAID up to 2 GeV. The channels included in the calculations are $\\pi N$, $\\eta N$ and $\\pi\\pi N$ which has $\\pi\\Delta$, $\\rho N$, and $\\sigma N$ resonant components. The non-resonant meson-baryon interactions of the model are derived from a set of Lagrangians by using a unitary transformation method. One or two bare excited nucleon states in each of $S$, $P$, $D$, and $F$ partial waves are included to generate the resonant amplitudes in the fits. The predicted total cross sections of $\\pi N$ reactions and $\\pi N\\rightarrow \\eta N$ reactions are in good agreement with the data. Applications of the constructed model in analyzing the electromagnetic meson production data as well as the future developments are discussed.

A measurement of the magnetic dipole moment of the. delta. /sup + +/(1232) from the bremsstrahlung process. pi. p. -->. pi. p. gamma  

SciTech Connect

We have measured the cross section from the bremsstrahlung process ..pi../sup +/p ..-->.. ..pi../sup +/p..gamma.. for incident pions of energy 299 MeV. We detected the out going pion in the angular range from 55 to 95/sup 0/ in the lab, and photons were detected near 240/sup 0/ in the lab. We compare this measured cross-section to the MIT theory in order to extract a measurement of the magnetic dipole moment of the ..delta../sup + +/(1232), ..mu../sub ..delta../. In order to compare our results with the MIT theory, we have folded the MIT theory into the acceptance of our apparatus. We find that for pion angles between 55 and 75/sup 0/ the theory gives us a dipole moment of: 2.3..mu../sub p/ < ..mu../sub ..delta../ < 3.3..mu../sup p/ where the quoted error arises from an experimental uncertainty of +-0.25..mu../sub p/ and from theoretical uncertainties of +-0.25 ..mu../sub p/. However, for pion angles between 75 and 95/sup 0/ we find that the MIT theory predicts a cross-section which is larger than our measured cross-section, and makes it difficult to extract a value of ..mu../sub ..delta../. This over prediction is not understood, but consistent with a similar effect when the MIT theory is fit to previous data. 78 figs., 29 tabs.

Determination of J/{psi} leptonic branching fraction via {psi}(2S){r_arrow}{pi}{sup +}{pi}{sup {minus}}J/{psi}

A comparison of the rates for {psi}(2S){r_arrow}{pi}{sup +}{pi}{sup {minus}}J/{psi}, J/{psi}{r_arrow}l{sup +}l{sup {minus}} and J/{psi}{r_arrow} anything is used to determine the J/{psi} leptonic branching fractions. The results are B(J/{psi}{r_arrow}e{sup +}e{sup {minus}})=(5.90{plus_minus}0.05{plus_minus}0.10){percent} and B(J/{psi}{r_arrow}{mu}{sup +}{mu}{sup {minus}})=(5.84{plus_minus}0.06{plus_minus}0.10){percent}, where the first error is statistical and the second is systematic. Assuming lepton universality, the leptonic branching fraction of the J/{psi} is B(J/{psi}{r_arrow}l{sup +}l{sup {minus}})=(5.87{plus_minus}0.04{plus_minus}0.09){percent} per species. This result is used to estimate the QCD scale factor {Lambda}{sub {ovr MS}}{sup (4)} and the strong coupling constant {alpha}{sub s}. {copyright} {ital 1998} {ital The American Physical Society}

Direct measurement of the {ital D}{sub {ital s}} branching fraction to {phi}{pi}  

Science Conference Proceedings (OSTI)

The Beijing Spectrometer (BES) Collaboration has observed exclusive pair production of {ital D}{sub {ital s}} mesons at the Beijing Electron-Positron Collider (BEPC) at a center-of-mass energy of 4.03 GeV. The {ital D}{sub {ital s}} mesons are detected in the {phi}{pi}{sup +}, {ital {bar K}} {sup *0}{ital K}{sup +}, and {ital {bar K}} {sup 0}{ital K}{sup +} decay modes; two fully reconstructed events yield the value (3.9{sub {minus}1.9{minus}1.1}{sup +5.1+1.8})% for the {ital D}{sub {ital s}} branching fraction to {phi}{pi}. This is the first direct, model-independent measurement of this quantity.

Coherent photoproduction of pi+ from He-3 with CLAS at Jefferson Laboratory  

Science Conference Proceedings (OSTI)

We have measured the differential cross section for the {gamma}{sup 3}He {yields} t{pi}{sup +} reaction. This reaction was studied using the CEBAF Large Acceptance Spectrometer (CLAS) at Jefferson Lab. Real photons produced with the Hall-B bremsstrahlung tagging system in the energy range from 0.5 to 1.55 GeV were incident on a cryogenic liquid {sup 3}He target. The differential cross sections for the {gamma}{sup 3}He {yields} i{pi}{sup +}t reaction were measured as a function of photon-beam energy and pion-scattering angle Theoretical predictions to date cannot explain the large cross sections except at backward angles, showing that additional components must be added to the model.

Elastic and radiative pi^+p scattering and properties of the Delta^{++} resonance  

E-Print Network (OSTI)

We study the Delta^{++} contributions to elastic and radiative \\pi^+p scattering within an effective Lagrangian model which incorporates the Delta, N, rho and sigma meson degrees of freedom. This model provides a description of the Delta resonance and its interactions that respects electromagnetic gauge invariance and invariance under contact transformations when finite width effects are incorporated. Following recent developments in the description of unstable gauge bosons, we use a complex mass scheme to introduce the finite width of the Delta^{++} without spoiling gauge invariance. The total cross section of elastic \\pi^+p scattering, whose amplitude exhibits the resonant plus background structure of S-matrix theory, is used to fix the mass, width and strong coupling of the \\Delta resonance. The differential cross section of elastic scattering is found in very good agreement with experimental data. The magnetic dipole moment of the Delta^{++}, \\mu_{Delta}, is left as the only adjustable parameter in radiative \\pi^+p scattering. From a fit to the most sensitive configurations for photon emission in this process, we obtain \\mu_{\\Delta} = (6.14 +-0.51)e/2m_p, in agreement with predictions based on the SU(6) quark model.

Isobar-hole doorway states and. pi. -/sup 16/O scattering  

SciTech Connect

We describe and apply the isobar-hole approach to intermediate energy pion-nucleus reactions. Pion propagation, nucleon and isobar binding, Pauli restrictions and ..delta.. propagation are calculated explicitly within a shell model framework. Intermediate coupling to multihole channels, for example through pion absorption, is treated phenomenologically through an isobar spreading potential. We find strongly collective ..delta..-hole states, leading to a reformulation of the approach in an extended schematic model. This entails systematic construction of a ..delta..-hole doorway state basis within which the ..delta..-hole propagator is evaluated. We find that this doorway space can be truncated at very low dimensionaltiy while preserving accuracy, thereby simplifying the calculations appreciably. We make a detailed comparison between the theoretical results and recent data for ..pi../sup +/--/sup 16/O scattering in the pion energy range 50--340 MeV. Nonresonant ..pi..N interactions and the ..pi..-nucleus Coulomb interaction are included in the calculations. The data is reproduced quite well both below and in the resonance region, and we discuss in detail the role of various dynamical mechanisms. Above the resonance, the calculations are far less successful. We discuss possible shortcomings, stressing the role of inclusive pion-nucleus reactions for revealing the important dynamics. As a test of the ..delta.. spreading potential used for describing elastic scattering, we calculate the total cross section for pion absorption. The result agrees reasonably well with the available data.

A new limit on the CP violating decay KS -> 3pi0 with the KLOE experiment  

E-Print Network (OSTI)

We have carried out a new direct search for the CP violating decay KS -> 3pi0 with 1.7 fb^-1 of e+e- collisions collected by the KLOE detector at the phi-factory DAFNE. We have searched for this decay in a sample of about 5.9 x 10^8 KS KL events tagging the KS by means of the KL interaction in the calorimeter and requiring six prompt photons. With respect to our previous search, the analysis has been improved by increasing of a factor four the tagged sample and by a more effective background rejection of fake KS tags and spurious clusters. We find no candidates in data and simulated background samples, while we expect 0.12 standard model events. Normalizing to the number of KS -> 2pi0 events in the same sample, we set the upper limit on BR(KS -> 3pi0 < 2.6 x 10^-8 at 90% C.L., five times lower than the previous limit. We also set the upper limit on the eta_000 parameter, |eta_000 | < 0.0088 at 90% C.L., improving by a factor two the latest direct measurement.

Investigation of astrophysical phenomena in short time scales with "Pi of the Sky" apparatus  

E-Print Network (OSTI)

In this thesis the data analysis designed by author for the "Pi of the Sky" experiment is presented. The data analysis consists of data reduction and specific algorithms for identification of short time scale astrophysical processes. The algorithms have been tested and their efficiency has been determined and described. The "Pi of the Sky" prototype is collecting data since June 2004 and algorithms could be intensively studied and improved during over 700 nights. A few events of confirmed astrophysical origin and above 100 events in 10s time scale of unknown nature have been discovered. During the data collection period 3 Gamma Ray Bursts (out of 231) occurred in the field of view of the telescope, but no optical counterpart has been found. The upper limits for brightness of the optical counterpart have been determined. The continuous monitoring of the sky and own trigger for optical flashes allowed to determine limits on the number of GRBs without corresponding gamma-ray detection. This allowed determining limits on the ratio of emission collimation in optical and gamma bands, which is R >= 4.4. The perspectives of the full "Pi of the Sky" system has been studied and number of positive detections has been estimated on the level of ~ 2.5 events per year.

EBAC-DCC Analysis of World Data of pi N, gamma N, and N(e,e') Reactions  

SciTech Connect

The development, results, and prospect of the Dynamical Coupled-Channels analysis at Excited Baryon Analysis Center (EBAC-DCC) are reported. In this contribution, we report on the development, results, and prospect of EBAC. The EBAC project has three components, as illustrated in Fig. 1. The first task is to perform a dynamical coupled-channels analysis of the world data of {pi}N, {gamma}*N {yields} {pi}N, {eta}N, {pi}{pi}N, K{Lambda}, K{Sigma}, {omega}N, {hor_ellipsis} to determine the meson-baryon partial-wave amplitudes. The second step is to develop a procedure to extract the N* parameters from the determined partial-wave amplitudes. The third step is to investigate the interpretations of the extracted N* properties in terms of the available hadron models and Lattice QCD.

Low energy analysis of $\\pi N$ scattering and the pion-nucleon sigma term with covariant baryon chiral perturbation theory  

E-Print Network (OSTI)

The pion-nucleon sigma term ($\\sigma_{\\pi N}$) is an observable of fundamental importance because embodies information about the internal scalar structure of the nucleon. Nowadays this quantity has triggered renewed interest because it is a key input for a reliable estimation of the dark matter-nucleon spin independent elastic scattering cross section. In this proceeding we present how this quantity can be reliably extracted by employing only experimental information with the use covariant baryon chiral perturbation theory. We also contrast our extraction with updated phenomenology related to $\\sigma_{\\pi N}$ and show how this phenomenology favours a relatively large value of $\\sigma_{\\pi N}$. Finally, we extract a value of $\\sigma_{\\pi N}=59(7)$ MeV from modern partial wave analyses data.

IQGAP Proteins Reveal an Atypical Phosphoinositide (aPI) Binding Domain with a Pseudo C2 Domain Fold  

SciTech Connect

Class I phosphoinositide (PI) 3-kinases act through effector proteins whose 3-PI selectivity is mediated by a limited repertoire of structurally defined, lipid recognition domains. We describe here the lipid preferences and crystal structure of a new class of PI binding modules exemplified by select IQGAPs (IQ motif containing GTPase-activating proteins) known to coordinate cellular signaling events and cytoskeletal dynamics. This module is defined by a C-terminal 105-107 amino acid region of which IQGAP1 and -2, but not IQGAP3, binds preferentially to phosphatidylinositol 3,4,5-trisphosphate (PtdInsP3). The binding affinity for PtdInsP3, together with other, secondary target-recognition characteristics, are comparable with those of the pleckstrin homology domain of cytohesin-3 (general receptor for phosphoinositides 1), an established PtdInsP3 effector protein. Importantly, the IQGAP1 C-terminal domain and the cytohesin-3 pleckstrin homology domain, each tagged with enhanced green fluorescent protein, were both re-localized from the cytosol to the cell periphery following the activation of PI 3-kinase in Swiss 3T3 fibroblasts, consistent with their common, selective recognition of endogenous 3-PI(s). The crystal structure of the C-terminal IQGAP2 PI binding module reveals unexpected topological similarity to an integral fold of C2 domains, including a putative basic binding pocket. We propose that this module integrates select IQGAP proteins with PI 3-kinase signaling and constitutes a novel, atypical phosphoinositide binding domain that may represent the first of a larger group, each perhaps structurally unique but collectively dissimilar from the known PI recognition modules.

DETECTION OF NONPOLAR IONS IN {sup 2}{Pi}{sub 3/2} STATES BY RADIOASTRONOMY VIA MAGNETIC DIPOLE TRANSITIONS  

Science Conference Proceedings (OSTI)

The possibility of magnetic dipole-induced pure rotational transitions in the interstellar medium is investi- gated for symmetric Hund's case (a) linear molecules, such as H-C{identical_to}C-H{sup +} (X-tilde {sup 2}{Pi}{sub 3/2u}), CO{sub 2} {sup +} (X-tilde {sup 2}{Pi}{sub 3/2g}), H-C{identical_to}C-C{identical_to}C-H{sup +} (X-tilde {sup 2}{Pi}{sub 3/2g}), and N{sub 3} (X-tilde {sup 2}{Pi}{sub 3/2g}). These species lack an electric dipole moment and therefore cannot undergo pure rotational electric dipole transitions. These species can undergo pure rotational transitions via the parallel component of the magnetic dipole operator, however. The transition moments and Einstein A coefficients for the allowed pure rotational transitions are derived for a general Hund's case (a) linear molecule, and tabulated for the examples of H-C{identical_to}C-H{sup +} ({sup 2}{Pi}{sub 3/2u}) and H-C{identical_to}C-C{identical_to}C-H{sup +} ({sup 2}{Pi}{sub 3/2g}). It is found that the rates of emission are comparable to collision rates in interstellar clouds, suggesting that this decay mechanism may be important in simulating rotational population distributions in diffuse clouds and for detecting these molecules by radioastronomy. Expected line positions for the magnetic dipole-allowed R{sub ef} (J) and R{sub fe} (J) transitions of H-C{identical_to}C-H{sup +} ({sup 2}{Pi}{sub 3/2u}), H-C{identical_to}C-C{identical_to}C-H{sup +} ({sup 2}{Pi}{sub 3/2g}), CO{sub 2}{sup +} ({sup 2}{Pi}{sub 3/2g}), and N{sub 3} ({sup 2}{Pi}{sub 3/2g}) are tabulated to assist in their observation by radioastronomy or in the laboratory.

Energy Calibration of the BaBar EMC Using the Pi0 Invariant Mass Method  

SciTech Connect

The BaBar electromagnetic calorimeter energy calibration method was compared with the local and global peak iteration procedures, of Crystal Barrel and CLEO-II. An investigation was made of the possibility of {Upsilon}(4S) background reduction which could lead to increased statistics over a shorter time interval, for efficient calibration runs. The BaBar software package was used with unreconstructed data to study the energy response of the calorimeter, by utilizing the {pi}{sup 0} mass constraint on pairs of photon clusters.

Scalar O(N) Model at Finite Temperature -- 2PI Effective Potential in Different Approximations  

E-Print Network (OSTI)

We calculate the two-particle irreducible (2PI) effective potential of the O(N) linear sigma model in 1+1 dimensions. The approximations we use are the next-to-leading order of a 1/N expansion (for arbitrary N) and a kind of "resummed loop approximation" for N=1. We show that the effective potential of the 1/N expansion is convex for N=4 and N=10 whereas it is not for the "loop" expansion and the case N=1 of the 1/N expansion.

The CP-violating decay rate asymmetry A_CP is determined to be (0.35 +- 0.30 +- 0.15)%. Model-dependent and model-independent Dalitz plot analysis techniques are used to search for CP-violating asymmetries in the various intermediate states.

BuildingPI: A future tool for building life cycle analysis  

SciTech Connect

Traditionally building simulation models are used at the design phase of a building project. These models are used to optimize various design alternatives, reduce energy consumption and cost. Building performance assessment for the operational phase of a buildings life cycle is sporadic, typically working from historical metered data and focusing on bulk energy assessment. Building Management Systems (BMS) do not explicitly incorporate feedback to the design phase or account for any changes, which have been made to building layout or fabric during construction. This paper discusses a proposal to develop an Industry Foundation Classes (IFC) compliant data visualization tool Building Performance Indicator (BuildingPI) for performance metric and performance effectiveness ratio evaluation.

Using data from the FOCUS (E831) experiment at Fermilab, we present a new measurement of the weak decay-asymmetry parameter alpha(Lambdac) in Lambdac --> Lambda pi decay. Comparing particle with antiparticle decays, we obtain the first measurement of the CP violation parameter : A = [alpha(Lambdac)+alpha(antiLambda_c)]/[alpha(Lambdac)-alpha(antiLambda_c)]. We obtain alpha(Lambdac)=-0.78+-0.16+-0.13 and A = -0.07+-0.19+-0.12 where errors are statistical and systematic.

The crystal structure of {pi}-ErBO{sub 3}: New single-crystal data for an old problem  

Science Conference Proceedings (OSTI)

Single crystals of the orthoborate {pi}-ErBO{sub 3} were synthesized from Er{sub 2}O{sub 3} and B{sub 2}O{sub 3} under high-pressure/high-temperature conditions of 2 GPa and 800 {sup o}C in a Walker-type multianvil apparatus. The crystal structure was determined on the basis of single-crystal X-ray diffraction data, collected at room temperature. The title compound crystallizes in the monoclinic pseudowollastonite-type structure, space group C2/c, with the lattice parameters a=1128.4(2) pm, b=652.6(2) pm, c=954.0(2) pm, and {beta}=112.8(1){sup o} (R{sub 1}=0.0124 and wR{sub 2}=0.0404 for all data). -- graphical abstract: The first satisfying single-crystal structure determination of {pi}-ErBO{sub 3} sheds light on the extensively discussed structure of {pi}-orthoborates. The application of light pressure during the solid state synthesis yielded in high-quality crystals, due to pressure-induced crystallization. Research highlights: {yields} High-quality single crystals of {pi}-ErBO{sub 3} were prepared via high-pressure-induced crystallization. {yields} At least five different space groups for the rare-earth {pi}-orthoborates are reported. {yields} {pi}-ErBO{sub 3} is isotypic to the pseudowollastonite-type CaSiO{sub 3}. {yields} Remaining ambiguities regarding the structure of the rare-earth {pi}-orthoborates are resolved.

Study on Control Performance of HVAC System or Interior Zone and Perimeter Zone in Office Building; Estimation of Optimal PI Tuning in Cooling Operation  

E-Print Network (OSTI)

In office buildings there are generally two HVAC systems installed, one in the perimeter zone (PZ) and one in the interior zone (IZ), and the temperatures of each zone are independently controlled. In the present paper, in order to the solve problem of not being able to satisfy the requirements of room temperature control during the cooling period in summer, an optimal PID parameter (O-PI) is selected through simulation of its two feedback control systems with mutual influence using the models identified with the experimental data. The step response characteristics of the system with optimal parameters compared to those with the parameters selected by the Ziegler-Nichols Method (ZNM-PI) that are generally used for PID parameter tuning on site. The result shows O-PI improved control performance, and the difference between O-PI and ZNM-PI can be used to readjust ZNM-PI selected on site.

The exclusive electroproduction of {pi}{sup +} above the resonance region was studied using the CEBAF Large Acceptance Spectrometer (CLAS) at Jefferson Laboratory by scattering a 6 GeV continuous electron beam off a hydrogen target.

Coherent photoproduction of pi^0- and eta-mesons off 7Li  

E-Print Network (OSTI)

Coherent photoproduction of $\\pi^0$-mesons from threshold ($E_{th} \\approx$ 136 MeV) throughout the $\\Delta$-resonance region and of $\\eta$-mesons close to the production threshold ($E_{th} \\approx$ 570 MeV for $\\eta$) has been measured for $^7$Li nuclei. The experiment was performed using the tagged-photon beam of the Mainz MAMI accelerator with the Crystal Ball and TAPS detectors combined to give an almost 4$\\pi$ solid-angle electromagnetic calorimeter. The reactions were identified by a combined invariant-mass and missing-energy analysis. A comparison of the pion data to plane-wave impulse modelling tests the nuclear mass form factor. So far coherent $\\eta$-production had been only identified for the lightest nuclear systems ($^2$H and $^3$He). For $^3$He a large enhancement of the cross section above plane-wave approximations had been reported, indicating the formation of a quasi-bound state. The present Li-data for $\\eta$-production agree with a plane-wave approximation. Contrary to $^3$He, neither a threshold enhancement of the total cross section nor a deviation of the angular distributions from the expected form-factor dependence were observed.

Pi-Josephson Junction and Spontaneous Superflow in Rings from Ultracold Fermionic Atomic Gases  

E-Print Network (OSTI)

The BCS-like pairing in ultracold fermionic atomic ($UCFAG$) gases is studied in the model of "isotopic-spin" pairing proposed in 1991 \\cite% {Ku-Hof-SSC}. This model assumes a mismatch ($\\delta $) in chemical potentials of pairing fermionic atoms. It is shown that a $\\pi $-Josephson junction can be realized in $UCFAG$ systems, where the left and right banks $% S$ are the $UCFAG$ superfluids. The weak link $M$ consists from the normal $% UCFAG$ with the finite mismatch $\\delta $. If the $\\pi $-junction is a part of a closed ring the superfluid mass-current flows spontaneously in the ring, i.e., the time-reversal symmetry is broken spontaneously. This is realized if the radius of the ring $R$ is larger than the critical one $% R_{c} $. All these effects exist also in the case when $\\delta \\gg \\Delta $, where $\\Delta $ is the superfluid gap, but with the reduced thickness of the weak link. It is also discussed, that if junctions $SM_{1}M_{2}S$ and trilayers $% M_{1}SM_{2}$ from $UCFAG$ are realizable this renders a possibility for a novel electronics - \\textit{hypertronics}.

Leptonic decay-constant ratio f_{K^+}/f_{pi^+} from lattice QCD with physical light quarks  

E-Print Network (OSTI)

A calculation of the ratio of leptonic decay constants f_{K^+}/f_{\\pi^+} makes possible a precise determination of the ratio of CKM matrix elements |V_{us}|/|V_{ud}| in the Standard Model, and places a stringent constraint on the scale of new physics that would lead to deviations from unitarity in the first row of the CKM matrix. We compute f_{K^+}/f_{\\pi^+} numerically in unquenched lattice QCD using gauge-field ensembles recently generated that include four flavors of dynamical quarks: up, down, strange, and charm. We analyze data at four lattice spacings a ~ 0.06, 0.09, 0.12, and 0.15 fm with simulated pion masses down to the physical value 135 MeV. We obtain f_{K^+}/f_{\\pi^+} = 1.1947(26)(37), where the errors are statistical and total systematic, respectively. This is our first physics result from our N_f = 2+1+1 ensembles, and the first calculation of f_{K^+}/f_{\\pi^+} from lattice-QCD simulations at the physical point. Our result is the most precise lattice-QCD determination of f_{K^+}/f_{\\pi^+}, with an error comparable to the current world average. When combined with experimental measurements of the leptonic branching fractions, it leads to a precise determination of |V_{us}|/|V_{ud}| = 0.2309(9)(4) where the errors are theoretical and experimental, respectively.

Light cone sum rules for the {pi}{sup 0}{gamma}{sup *}{gamma} form factor revisited  

Science Conference Proceedings (OSTI)

We provide a theoretical update of the calculations of the {pi}{sup 0}{gamma}{sup *}{gamma} form factor in the light cone sum rules framework, including up to six polynomials in the conformal expansion of the pion distribution amplitude and taking into account twist-six corrections related to the photon emission at large distances. The results are compared with the calculations of the B{yields}{pi}l{nu} decay and pion electromagnetic form factors in the same framework. Our conclusion is that the recent BABAR measurements of the {pi}{sup 0}{gamma}{sup *}{gamma} form factor at large momentum transfers [B. Aubert et al. (The BABAR Collaboration), Phys. Rev. D 80, 052002 (2009)] are consistent with QCD, although they do suggest that the pion distribution amplitude may have more structure than usually assumed.

Axonal regulation of Schwann cell proliferation and survival and the initial events of myelination requires PI 3-kinase activity  

E-Print Network (OSTI)

In this report, we have investigated the signaling pathways that are activated by, and mediate the effects of, the neuregulins and axonal contact in Schwann cells. Phosphatidylinositol 3-kinase (PI 3-kinase) and mitogen-activated protein kinase kinase (MAPK kinase) are strongly activated in Schwann cells by glial growth factor (GGF), a soluble neuregulin, and by contact with neurite membranes; both kinase activities are also detected in Schwann cell-DRG neuron cocultures. Inhibition of the PI 3-kinase, but not the MAP kinase, pathway reversibly inhibited Schwann cell proliferation induced by GGF and neurites. Cultured Schwann cells undergo apoptosis after serum deprivation and can be rescued by GGF or contact with neurites; these survival effects were also blocked by inhibition of PI 3-kinase. Finally, we have examined the role of these signaling pathways in Schwann cell differentiation in cocultures. At early stages of

The Role of Conformal Symmetry in the Jackiw-Pi Model  

E-Print Network (OSTI)

The Jackiw-Pi model in 2+1 dimensions is a non-relativistic conformal field theory of charged particles with point-like self-interaction. For specific values of the interaction strengths the classical theory possesses vortex and multi-vortex solutions, which are all degenerate in energy. We compute the full set of first-order perturbative quantum corrections. Only the coupling constant g^2 requires renormalization; the fields and electric charge e are not renormalized. It is shown that in general the conformal symmetries are broken by an anomalous contribution to the conservation law, proportional to the beta-function. However, the beta-function vanishes upon restricting the coupling constants to values g^2 = +/- e^2, which includes the case in which vortex solutions exist. Therefore the existence of vortices also guarantees the preservation of the conformal symmetries.

Non-Equilibrium 2PI Potential and Its Possible Application to Evaluation of Bulk Viscosity  

E-Print Network (OSTI)

Within non-equilibrium Green's function technique on the real-time contour and the two-particle-irreducable (2PI) $\\Phi$-functional method, a non-equilibrium potential is introduced. It naturally generalizes the conventional thermodynamic potential with which it coincides in thermal equilibrium. Variations of the non-equilibrium potential over respective parameters result in the same quantities as those of the thermodynamic potential but in arbitrary non-equilibrium. In particular, for slightly non-equilibrium inhomogeneous configurations a variation of the non-equilibrium potential over volume is associated with the trace of the non-equilibrium stress tensor. The latter is related to the bulk viscosity. This provides a novel way for evaluation of the bulk viscosity.

Measurement of $D^0-overline{D}^0$ mixing parameters using $D^0 \\to K_S^0 \\pi^ \\pi^-$ and $D^0 \\to K_S^0 K^ K^-$ decays  

Science Conference Proceedings (OSTI)

We report a direct measurement of D{sup 0}-{bar D}{sup 0} mixing parameters through a time-dependent amplitude analysis of the Dalitz plots of D{sup 0} {yields} K{sub S}{sup 0}{pi}{sup +}{pi}{sup -} and, for the first time, D{sup 0} {yields} K{sub S}{sup 0}K{sup +}K{sup -} decays. The low-momentum pion {pi}{sub s}{sup +} in the decay D*{sup +} {yields} D{sup 0}{pi}{sub s}{sup +} identifies the flavor of the neutral D meson at its production. Using 468.5 fb{sup -1} of e{sup +}e{sup -} colliding-beam data recorded near {radical}s = 10.6 GeV by the BABAR detector at the PEP-II asymmetric-energy collider at SLAC, we measure the mixing parameters x = [1.6 {+-} 2.3 (stat.) {+-} 1.2 (syst.) {+-} 0.8 (model)] x 10{sup -3}, and y = [5.7 {+-} 2.0 (stat.) {+-} 1.3 (syst.) {+-} 0.7 (model)] x 10{sup -3}. These results provide the best measurement to date of x and y. The knowledge of the value of x, in particular, is crucial for understanding the origin of mixing.

First Observation of Coherent pi0 Production in Neutrino Nucleus Interactions with E(nu) < 2-GeV  

DOE Green Energy (OSTI)

The MiniBooNE experiment at Fermilab has amassed the largest sample to date of {pi}{sup 0}s produced in neutral current (NC) neutrino-nucleus interactions at low energy. This paper reports a measurement of the momentum distribution of {pi}{sup 0}s produced in mineral oil (CH{sub 2}) and the first observation of coherent {pi}{sup 0} production below 2 GeV. In the forward direction, the yield of events observed above the expectation for resonant production is attributed primarily to coherent production off carbon, but may also include a small contribution from diffractive production on hydrogen. Integrated over the MiniBooNE neutrino flux, the sum of the NC coherent and diffractive modes is found to be (19.5 {+-} 1.1 (stat) {+-} 2.5 (sys))% of all exclusive NC {pi}{sup 0} production at MiniBooNE. These measurements are of immediate utility because they quantify an important background to MiniBooNE's search for {nu}{sub {mu}} {yields} {nu}{sub e} oscillations.

Study of B to pi l nu and B to rho l nu Decays and Determination of |V_ub|  

SciTech Connect

We present an analysis of exclusive charmless semileptonic B-meson decays based on 377 million B{bar B} pairs recorded with the BABAR detector at the {Upsilon} (4S) resonance. We select four event samples corresponding to the decay modes B{sup 0} {yields} {pi}{sup -}{ell}{sup +}{nu}, B{sup +} {yields} {pi}{sup 0}{ell}{sup +}{nu}, B{sup 0} {yields} {rho}{sup -}{ell}{sup +}{nu}, and B{sup +} {yields} {rho}{sup 0}{ell}{sup +}{nu}, and find the measured branching fractions to be consistent with isospin symmetry. Assuming isospin symmetry, we combine the two B {yields} {pi}{ell}{nu} samples, and similarly the two B {yields} {rho}{ell}{nu} samples, and measure the branching fractions {Beta}(B{sup 0} {yields} {pi}{sup -}{ell}{sup +}{nu}) = (1.41 {+-} 0.05 {+-} 0.07) x 10{sup -4} and {Beta}(B{sup 0} {yields} {rho}{sup 0}{ell}{sup +}{nu}) = (1.75 {+-} 0.15 {+-} 0.27) x 10{sup -4}, where the errors are statistical and systematic. We compare the measured distribution in q{sup 2}, the momentum transfer squared, with predictions for the form factors from QCD calculations and determine the CKM matrix element |V{sub ub}|. Based on the measured partial branching fraction for B {yields} {pi}{ell}{nu} in the range q{sup 2} < 12 GeV{sup 2} and the most recent LCSR calculations we obtain |V{sub ub}| = (3.78 {+-} 0.13{sub -0.40}{sup +0.55}) x 10{sup -3}, where the errors refer to the experimental and theoretical uncertainties. From a simultaneous fit to the data over the full q{sup 2} range and the FNAL/MILC lattice QCD results, we obtain |V{sub ub}| = (2.95 {+-} 0.31) x 10{sup -3} from B {yields} {pi}{ell}{nu}, where the error is the combined experimental and theoretical uncertainty.

The hot prototype of the Pi-mode structure for LINAC4  

E-Print Network (OSTI)

The PIMS (Pi-Mode-Structure) cavities for Linac4 are made of 7 coupled cells operating in !-mode at a frequency of 352 MHz. The mechanical concept is derived from the 5-cell cavities used in the LEP machine, whereas cell length and coupling are adapted for proton acceleration in the range from 50 to 160 MeV. Linac4 will be the first machine to employ this type of cavities for low-beta protons. During the first years of operation the PIMS will be used at low duty cycle (0.1%) as part of the consolidated LHC proton injector complex. It is designed, however, to operate eventually in a high duty cycle (10%) proton injector, which could be used as proton front-end for neutrino or RIB applications. To prepare for the series construction of the 12 PIMS units the first cavity (102 MeV beam energy) has been designed and constructed at CERN, to be used as a hot prototype for RF tests and as a pre-series mechanical unit. In this paper we report on some of the design features, the construction experience, and first measu...

Beam-helicity asymmetry in associated electroproduction of real photons $ep \\to e\\gamma \\pi N$ in the $\\Delta$-resonance region  

E-Print Network (OSTI)

The beam-helicity asymmetry in associated electroproduction of real photons, $ep\\to e\\gamma \\pi N$, in the $\\Delta$(1232)-resonance region is measured using the longitudinally polarized HERA positron beam and an unpolarized hydrogen target. Azimuthal Fourier amplitudes of this asymmetry are extracted separately for two channels, $ep\\to e\\gamma \\pi^0 p$ and $ep\\to e\\gamma \\pi^+ n$, from a data set collected with a recoil detector. All asymmetry amplitudes are found to be consistent with zero.

Vector analyzing power of {pi}{sup +7}Li scattering in the region of the {delta}{sub 33} resonance  

Science Conference Proceedings (OSTI)

Within Glauber diffraction theory, the vector analyzing power iT{sub 11} is calculated at three energies of positively charged pions, 134, 164, and 194 MeV, incident to {sup 7}Li nuclei. These energy values lie in the region of the {delta}{sub 33} resonance in {pi}{sup {+-}}N interaction, the resonance maximum being at 180 MeV. The calculation of iT{sub 11} was performed with several model {sup 7}Li wave functions, including the {alpha}t-cluster and shell-model ones. The properties of {pi}{sup +7}Li scattering are found to be sensitive to the structural features of the target nucleus. A comparison of the results of the calculations with experimental data shows that the wave functions in question and the potentials used to calculate them are quite appropriate.

Pion distribution amplitude from holographic QCD and the electromagnetic form factor F{sub {pi}}(Q{sup 2})  

Science Conference Proceedings (OSTI)

The holographic QCD prediction for the pion distribution amplitude (DA) {phi}{sub hol}(u) is used to compute the pion spacelike electromagnetic form factor F{sub {pi}}(Q{sup 2}) within the QCD light-cone sum rule method. In calculations the pion's renormalon-based model twist-4 DA, as well as the asymptotic twist-4 DA are employed. Obtained theoretical predictions are compared with experimental data and with results of the holographic QCD.

Measurement of spin observables in the quasi-free np-> {pp}_s pi- reaction at 353 MeV  

E-Print Network (OSTI)

The transverse spin correlations A_{x,x} and A_{y,y} have been measured in the pol{d} pol{p} -> p_spec {pp}_s pi- reaction at COSY-ANKE at 353 MeV per nucleon. Here {pp}_s denotes a proton-proton pair with low excitation energy, which is dominantly in the 1S0 state. By measuring three protons in the final state it was possible to extract events where there was a spectator proton p_spec so that the reaction could be interpreted in terms of quasi-free pol{n} pol{p} -> {pp}_s pi-. The proton analyzing power in this reaction was also deduced from this data set by averaging over the polarization of the deuteron beam. The values of A_y^p were shown to be consistent with a refined analysis of our earlier results obtained with a polarized proton incident on a deuterium target. Taking these data in combination with our earlier measurements of the differential cross sections and analyzing powers in the pol{p} p -> {pp}_s pi^0 reaction, a more robust partial wave decomposition was achieved. Three different acceptable solutions were found and the only way of resolving this ambiguity without further theoretical input would be through a measurement of the mixed spin-correlation parameter A_{x,z}.

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.

Subthreshold pion production in the reaction /sup 139/La + /sup 139/La. -->. pi. /sup + -/ + X  

Science Conference Proceedings (OSTI)

We have measured charged pion production in the reaction /sup 139/La + /sup 139/La ..-->.. ..pi../sup + -/ + X at three beam energies (246, 183 and 138 MeVnucleon) below the nucleon-nucleon threshold. Associated multiplicity for charged participants was obtained using a 110-element scintillator multiplicity array. Data were taken over the angular range of 21/degree/ to 67/degree/ in the laboratory (equivalent to 30/degree/ to 90/degree/ in the center of mass). Dependence of the spectra upon pion charge, energy and angle, beam energy, system mass and associated multiplicity was investigated. Based on the isotropic angular distibutions and the associated multiplicities for pion production, it appears that subthreshold pions in the range of our experiment are produced predominantly from a source at rest in the center of mass and involving a large number of nucleons. The general character of the subthreshold pion spectra is comparable to previous results above threshold. However, the scaling of the subthreshold pion yield with system mass deviates from the dependence observed in light systems, to an extent which cannot be explained by a simple nucleon-nucleon model. We also found charge dependent structure in the pion spectra, which we analysed in the framework of both Coulomb distortion and clustering models. We conclude that while we did not find clear evidence of collective effects in subthreshold pion production, it would be very worthwhile to conduct a systematic investigation of pion production for all charge states and over a range of angles, system masses and beam energies, below threshold. 170 refs., 78 figs., 10 tabs.

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.

Energy dependence of pi, p and pbar transverse momentum spectra for Au+Au collisions at sqrt sNN = 62.4 and 200 GeV  

Science Conference Proceedings (OSTI)

We study the energy dependence of the transverse momentum (pT) spectra for charged pions, protons and anti-protons for Au+Au collisions at sqrt sNN = 62.4 and 200 GeV. Data are presented at mid-rapidity (lbar y rbar 7 GeV/c) the modification is similar for both energies. The p/pi+ and pbar/pi- ratios for central collisions at sqrt sNN = 62.4 GeV peak at pT _~;; 2 GeV/c. In the pT range where recombination is expected to dominate, the p/pi+ ratios at 62.4 GeV are larger than at 200 GeV, while the pbar/pi- ratios are smaller. For pT> 2 GeV/c, the pbar/pi- ratios at the two beam energies are independent of pT and centrality indicating that the dependence of the pbar/pi- ratio on pT does not change between 62.4 and 200 GeV. These findings challenge various models incorporating jet quenching and/or constituent quark coalescence.

The p/pi ratio pT-dependence in the RHIC range od baryo-chemical potential  

E-Print Network (OSTI)

The BRAHMS measurement of proton-to-pion ratios in Au+Au and p+p collisions at 62.4 and 200 GeV is presented as a function of transverse momentum and collision centrality within the pseudorapidity range 0 = 1.5 GeV/c. For these energy and pseudorapidity interval no centrality dependency of p/pi ratio is observed. The baryon-to-meson ratio of nucleus-nucleus data are consistent with results obtained for p+p interactions.

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}.

Do the Defects Make It Work? Defect Engineering in Pi-Conjugated Polymers and Their Solar Cells: Preprint  

DOE Green Energy (OSTI)

The charged defect density in common pi-conjugated polymers such as poly(3-hexylthiophene), P3HT, is around 1018 cm-3. Despite, or perhaps because of, this huge defect density, bulk heterojunction solar cells made from these polymers and a C60 derivative such as PCBM exhibit some of the highest efficiencies (~5%) yet obtained in solid state organic photovoltaic cells. We discuss defects in molecular organic semiconductors and in pi-conjugated polymers. These defects can be grouped in two categories, covalent and noncovalent. Somewhat analogous to treating amorphous silicon with hydrogen, we introduce chemical methods to modify the density and charge of the covalent defects in P3HT by treating it with electrophiles such as dimethyl sulfate and nucleophiles such as sodium methoxide. The effects of these treatments on the electrical and photovoltaic properties and stability of organic PV cells is discussed in terms of the change in the number and chemical properties of the defects. Finally, we address the question of whether the efficiency of OPV cells requires the presence of these defects which function as adventitious p-type dopants. Their presence relieves the resistance limitations usually encountered in cleaner organic semiconductors and can create built-in electric fields at junctions.

Cascade production in the reactions gamma p --> K+ K+ (X) and gamma p --> K+ K+ pi- (X)  

SciTech Connect

Photoproduction of the cascade resonances has been investigated in the reactions {gamma}p {yields} K{sup +}K{sup +}(X) and {gamma}p {yields} K{sup +}K{sup +}{pi}{sup -}(X). The mass split of the {Xi} doublet is measured to be 5.4 {+-} 1.8 MeV/c{sup 2}, consistent with existing measurements. The differential (total) cross sections for the {Xi}{sup -} have been determined for photon beam energies from 2.75 to 3.85 (4.75) GeV, and are consistent with a possible production mechanism of Y* {yields} K{sup +}{Xi}{sup -} through a t-channel process. The reaction {gamma}p {yields} K{sup +}K{sup +}{pi}{sup -}({Xi}{sup 0}) has also been investigated in search of excited cascade resonances. No significant signal of excited cascade states other than the {Xi}{sup -}(1530) is observed. The cross section results of the {Xi}{sup -}(1530) have also been obtained for photon beam energies from 3.35 to 4.75 GeV.

Measurement of cross sections of p(e,e'pi^+)n for near pion threshold and high-lying resonances at high Q^2  

Science Conference Proceedings (OSTI)

During the last decade, remarkable experimental data have been collected in an extensive programs to study the excitation of nucleon resonance (N*) at Jefferson Laboratory through pion electroproduction using polarized electron beam and unpolarized proton target. The CEBAF Large Acceptance Spectrometer (CLAS) is well suited for the study of a broad range of kinematics in the invariant mass W and photon virtuality Q{sup 2} with nearly complete angular coverage for the hadronic decays. Electron scattering allows us to probe the effective degrees of freedom in excited nucleon states from meson-baryon to dressed quarks in terms of varying the distance scale. The study of nucleon structure allows us to understand these effective degrees of freedom. In this proceeding, I present preliminary cross sections for single pion production in mass range of high-lying resonances as well as near the pion threshold. Analysis of N{pi}{sup +} cross sections together with N{pi}{sup 0} and N {pi}{pi} exclusive electroproduction data, will allow us for the first time to determine electrocouplings of several high-lying excited proton states (W {ge} 1.6 GeV) at photon virtualities that correspond to the transition toward the dominance of quark degrees of freedom. I also present preliminary result on the E{sub 0+} multipole near pion threshold at 2.0 GeV{sup 2} {le} Q{sup 2} {le} 4.5 GeV{sup 2} using exclusive N{pi}{sup +} electroproduction data.

Density-Dependent Properties of Hadronic Matter in the self-consistent Chiral ({sigma},{pi},{omega}) Mean-Field Model  

Science Conference Proceedings (OSTI)

Density-dependent relations among saturation properties of symmetric nuclear matter and properties of hadronic stars are discussed by applying the conserving chiral nonlinear ({sigma},{pi},{omega}) hadronic mean-field theory. The chiral nonlinear ({sigma},{pi},{omega}) mean-field theory is an extension of the conserving nonlinear (nonchiral) {sigma}-{omega} hadronic mean-field theory which is thermodynamically consistent, relativistic and is a Lorentz-covariant mean-field theory of hadrons. In the extended chiral ({sigma},{pi},{omega}) mean-field model, all the masses of hadrons are produced by the breaking of chiral symmetry, which is different from other conventional chiral partner models. By comparing both nonchiral and chiral mean-field approximations, the effects of the chiral symmetry breaking mechanism on the mass of {sigma}-meson, coefficients of nonlinear interactions and Fermi-liquid properties are investigated in nuclear matter and neutron stars.

The funds provided under Contract No. DE-AC02-79ER10486 were totally expended for hardware and supplies required by two related devices at the Bates Linear Accelerator. These were a photon tagging facility and a ..gamma pi../sup 0/ spectrometer in Beam Line C of the new South Experimental Hall. Construction was begun in November of 1979 and both systems became fully operational in the summer of 1981. Preliminary data was taken in 1980 with a prototype ..gamma pi../sup 0/ spectrometer will be carried out in the fall of 1981 and spring of 1982. The photon tagging system has been used successfully to calibrate the ..gamma pi../sup 0/ spectrometer for the BU - MIT collaboration and to test a lead glass detector system for Brandeis University.

The experimental data from 2m propane bubble chamber have been analyzed to search for scalar meson $\\kappa(800)$ in a $K^0_s\\pi$ decay mode for the reaction p+$C_3H_8$ at 10 GeV/c. The $K^0_s\\pi^-$ invariant mass spectrum has shown resonant structures with $M_{K^0_s\\pi^-}$=730, 900 and $\\Gamma$=143, 48 MeV/$c^2$, respectively. The statistical significance are estimated to be of 14.2$\\sigma$ and 4.2$\\sigma$, respectively. The peak in M(900) is identified as reflection from the well known resonance with mass of 892 MeV/c$^2$.

Search for Theta+ via K+p -> pi+X reaction with a 1.2 GeV/c K+ beam  

E-Print Network (OSTI)

The Theta+ was searched for via the K+p -> pi+X reaction using the 1.2 GeV/c K+ beam at the K6 beam line of the KEK-PS 12 GeV Proton Synchrotron. In the missing mass spectrum of the K+p -> pi+X reaction, no clear peak structure was observed. Therefore a 90 % C.L. upper limit of 3.5 ub/sr was derived for the differential cross section averaged over 2degree to 22degree in the laboratory frame of the K+p -> pi+Theta+ reaction. This upper limit is much smaller than the theoretical calculation for the t-channel process where a K0* is exchanged. From the present result, either the t-channel process is excluded or the coupling constant of g_{K*N\\Theta} is quite small.

Measurement of single pi0 production in neutral current neutrino interactions with water by a 1.3 GeV wide band muon neutrino beam  

E-Print Network (OSTI)

Neutral current single pi0 production induced by neutrinos with a mean energy of 1.3 GeV is measured at a 1000 ton water Cherenkov detector as a near detector of the K2K long baseline neutrino experiment. The cross section for this process relative to the total charged current cross section is measured to be 0.064 +- 0.001 (stat.) +- 0.007 (sys.). The momentum distribution of produced pi0s is measured and is found to be in good agreement with an expectation from the present knowledge of the neutrino cross sections.

Experimental and Theoretical Investigations of Anion-pi Interactions Metallacyclic Architectures of First-Row Transition Metals and N-Heteroaromatic Ligands  

E-Print Network (OSTI)

Research into anion-pi interactions has shifted from attempts to establish the legitimacy of the interaction to the incorporation of anion-pi interactions into supramolecular architectures. The research discussed in this dissertation explores the subtle effects of ligand, anion, and metal ion on supramolecular architectures of tetrazine-based ligands in the context of anion-pi interactions and their importance in the design and synthesis of supramolecular architectures. Computational studies highlight the importance of the arene quadrupole moment, molecular polarizability, and substituent effects on the strength of anion-pi interactions. More importantly, however, this work establishes that there is a distinct directionality inherent to the anion-pi interaction between polyatomic anions and N-heterocycles, which can be used to direct ligands in supramolecular architectures as demonstrated through the work of the Dunbar group in recent years, particularly that of the square and pentagonal metallacycles. The extension of metallacycles of bptz to CoII and FeII demonstrates the ability to tune the size of the metallacyclic cavity by simply changing the metal ion and results in the surprising encapsulation of two [SbF6]- anions in [Fe5(bptz)5(NCCH3)10][SbF6]10. 1H NMR spectroscopy and electrochemical studies reveal slight but significant differences characteristic of the square and pentagonal metallacycles and support the presence of anion-pi interactions in solution and highlight the importance of the encapsulated anion in the templation and stability of the metallacycles. A study of the interconversion between the square and pentagonal metallacycles via 1H NMR is presented for the first time. Increasing the pi-acidity of the chelating ligand from bptz to bmtz results in the encapsulation of only one [SbF6]- anion in [Fe5(bmtz)5(NCCH3)10][SbF6]10, maximizing anion-pi interactions with the ligand despite the tighter fit. A significant hurdle in the incorporation of different anions into the metallacyclic structures was overcome with the development of a new synthetic protocol for [Fe(NCCH3)6]2+ salts of a wide range of anions from sodium salts and Fe4Cl8(THF)6. Also, the nuclearity of the less stable [Fe5(bptz)5(NCCH3)10][PF6]10 metallacycle was established via a combination of MS, electrochemistry and 1H NMR experiments through comparisons with known FeII metallacycle solution behavior.

The authors present measurements of partial branching fractions of B {yields} K{sup +}X, B {yields} K{sup 0} X, and B {yields} {pi}{sup +}X, where X denotes any accessible final state above the endpoint for B decays to charmed mesons, specifically for momenta of the candidate hadron greater than 2.34 (2.36) GeV for kaons (pions) in the B rest frame. These measurements are sensitive to potential new-phisics particles which could enter the b {yields} s(d) loop transitions. The analysis is performed on a data sample consisting of 383 x 10{sup 6} B{bar B} pairs collected with the BABAR detector at the PEP-II e{sup +}e{sup -} asymmetric energy collider. The results are in agreement with standard model predictions and exclude large enhancements of the inclusive branching fraction due to sources of new physics.

Huge right-handed current effects in B->K*(K pi)l+l- in supersymmetry

Transverse asymmetries in the decay B {yields} K*(K{pi}){ell}{sup +}{ell}{sup -} are an extremely sensitive probe of right-handed flavor-changing neutral currents. They show how to include the contribution from the chiral partner of the electromagnetic operator on the transverse asymmetries at NLO in QCD factorization. They then consider supersymmetric models with non-minimal flavor violation in the down-squark sector. They include all the relevant experimental constraints and present a numerical formula for B {yields} X{sub s}{gamma} that takes into account the most recent NNLO calculations. they show that the flavor-changing parameters of these models are poorly constrained by present data and allow for large effects on the transverse asymmetries that they consider.

Measurement of the numu Charged Current pi+ to Quasi-Elastic Cross Section Ratio on Mineral Oil in a 0.8 GeV Neutrino Beam  

SciTech Connect

Charged current single pion production (CC{pi}{sup +}) and charged current quasi-elastic scattering (CCQE) are the most abundant interaction types for neutrinos at energies around 1 GeV, a region of great interest to oscillation experiments. The cross-sections for these processes, however, are not well understood in this energy range. This dissertation presents a measurement of the ratio of CC{pi}{sup +} to CCQE cross-sections for muon neutrinos on mineral oil (CH{sub 2}) in the MiniBooNE experiment. The measurement is presented here both with and without corrections for hadronic re-interactions in the target nucleus and is given as a function of neutrino energy in the range 0.4 GeV < E{sub {nu}} < 2.4 GeV. With more than 46,000 CC{pi}{sup +} events collected in MiniBooNE, and with a fractional uncertainty of roughly 11% in the region of highest statistics, this measurement represents a dramatic improvement in statistics and precision over previous CC{pi}{sup +} and CCQE measurements.

Study of leading strange meson resonances and spin-orbit splittings in K/sup -/p. -->. K/sup -/. pi. /sup +/n at 11 GeV/c  

Science Conference Proceedings (OSTI)

The results from a high-statistics study of K..pi.. elastic scattering in the reaction K/sup -/p ..-->.. K/sup -/..pi../sup +/n are presented. The data for this analysis are taken from an 11-GeV/c K/sup -/p experiment performed on the Large Aperture Solenoidal Spectrometer (LASS) facility at the Stanford Linear Accelerator Center (SLAC). By selecting the very forward produced K/sup -/..pi../sup +/ events, a sample consisting of data for the K..pi.. ..-->.. K..pi.. elastic scattering reaction was extracted. The angular distribution for this meson-meson scattering is studied by use of both a spherical harmonic moments analysis and a partial-wave analysis (PWA). The previously established leading natural spin-parity strange meson resonances (the J/sup P/ = 1/sup -/ K*(895), the 2/sup +/ K*(1430), and the 3/sup -/ K*(1780)) are observed in the results from both the moments analysis and the PWA. In addition, evidence for a new spin 4/sup -/ K* resonance with a mass of 2080 MeV and a width of about 225 MeV is presented. The results from the PWA confirm the existence of a 0/sup +/ kappa (1490) and propose the existence of a second scalar meson resonance, the 0/sup +/ kappa' (1900). Structure in the P-wave amplitude indicates resonance behavior in the mass region near 1700 MeV. In two of the four ambiguous solutions for the mass region above 1800 MeV, there is strong evidence for another P-wave resonant structure near 2100 MeV. The observed strange meson resonances are found to have a natural interpretation in terms of states predicted by the quark model. In particular, the mass splittings of the leading trajectory natural spin-parity strange meson states and the mass splittings between the spin-orbit triplet states are discussed. 59 figures, 17 tables.

From these, the relative branching ratio of $B^0\\to D^- K^+$ with respect to $B^0\\to D^- \\pi^+$ is determined, resulting in $B\\left(B^0\\to D^- K^+\\right) = (2.02 \\pm 0.17^{\\textrm{stat}} \\pm 0.12^{\\textrm{syst}})\\times 10^{-4}$. The ratio of fragmentation fractions $f_s/f_d$~is determined through the relative abundances of $B^0\\to D^- K^+$ and $B^0\\to D^- \\pi^+$ with respect to $B^0_s \\to D^-_s \\pi^+$, leading to $f_s/f_d = 0.245 \\pm 0.017^{\\textrm{stat}} \\pm 0.018^{\\textrm{syst}} \\pm 0.018^{\\textrm{theor}}$.

Study of natural spin-parity strange meson radial excitations in K/sup -/p. -->. K/sup -/. pi. /sup +/n at 11 GeV/c  

SciTech Connect

Results are presented from a high statistics study of the reaction K/sup -/p ..-->.. K/sup -/..pi../sup +/n at 11 GeV/c. This data was selected offline from an approx. 1000 event/..mu..b K/sup -/p experiment run on the Large Aperture Solenoid Spectrometer (LASS) at SLAC which triggered on essentially the total inelastic cross section. This K/sup -/..pi../sup +/n sample, after cuts, contained approx. 42,000 events in the K..pi.. invariant mass region from 0.65 GeV to 2.30 GeV, and absolute value t' < 0.2 GeV/sup 2/. A spherical harmonic angular moments analysis of this data is presented, as well as an energy independent partial wave analysis (PWA) of these angular moments. The nearly uniform acceptance characteristics of this data allowed a detailed analysis, which yielded information on natural spin-parity strange meson resonances in the K..pi.. invariant mass range from 0.65 GeV to 2.30 GeV. The well established K*(895), K*(1430), and K*(1780) are observed, and clear evidence is presented for a J/sup P/ = 4/sup +/ strange meson state at a mass of 2.08 GeV. The K/sup -/..pi../sup +/ elastic scattering partial waves extracted in this PWA show unambiguous evidence for a relatively narrow S wave resonance near 1.42 GeV in the K..pi.. invariant mass. This state is a confirmation of the 0/sup +/ K(1500) seen in previous PWA's. A new higher S wave resonance is clearly seen unambiguously near 1.90 GeV. Unambiguous evidence is presented for a relatively wide P wave resonance in the 1.70 GeV region.A second new P wave resonance also is seen in two of four ambiguous partial wave solutions in the 2.10 GeV region. These resonance states are discussed within the framework of a simple harmonic oscillator quark model. In particular three of the underlying resonances are discussed as possible natural spin-parity strange meson radial excitations.

Cyclopentacorannulene: {pi}-facial stereoselective deuterogenation and determination of the bowl-to-bowl inversion barrier for a constrained buckybowl  

SciTech Connect

Attachment of an ethane or ethylene unit to the rim of corannulene produced relatively rigid bowls of dihydrocyclopenta- and cyclopentacorannulene, respectively. In contrast to the parent corannulenes, their inversion barriers are too high to be determined by the NMR coalescence methods. Due to the significant curvature of cyclopentacorannulene, deuterogenation is {pi}-facial specific; both heterogeneous and homogeneous catalysis lead exclusively to exo-dideuteriocyclopentacorannulene 2a. Equilibration of the endo- and exo-isotopomers allowed the determination of {Delta}G{sup {dagger}} at 27.61-27.67 kcal/mol over the temperature range 52.1-99.3{degree}C and the estimation of {Delta}H{sup {dagger}} (27.3{+-}0.7 kcal/mol) and {Delta}S{sup {dagger}} (-1.1{+-}0.2 eu) for the bowl-to-bowl inversion. The inversion barrier calculated at the HF/6-31G{sup *}//3-21G level (25.9 kcal/mol) compares well with the experimental result. 20 refs., 3 figs., 1 tab.

THE MAGNESIUM ISOTOPOLOGUES OF MgH IN THE A {sup 2}{Pi}-X {sup 2}{Sigma}{sup +} SYSTEM  

Science Conference Proceedings (OSTI)

Using laboratory hollow cathode spectra we have identified lines of the less common magnesium isotopologues of MgH, {sup 25}MgH and {sup 26}MgH, in the A {sup 2}{Pi}-X {sup 2}{Sigma}{sup +} system. Based on the previous analysis of {sup 24}MgH, molecular lines have been measured and molecular constants derived for {sup 25}MgH and {sup 26}MgH. Term values and linelists, in both wavenumber and wavelength units, are presented. The A {sup 2}{Pi}-X {sup 2}{Sigma}{sup +} system of MgH is important for measuring the magnesium isotope ratios in stars. Examples of analysis using the new linelists to derive the Mg isotope ratio in a metal poor dwarf and giant are shown.

Ambiguity-Free Measurement of cos2beta: Time-Intergrated and Time-Dependent Angular Analyses of B to J/psi K pi  

Science Conference Proceedings (OSTI)

We present results on B {yields} J/{psi} K{pi} decays using e{sup +}e{sup -} annihilation data collected with the BABAR detector at the {Upsilon}(4S) resonance. The detector is located at the PEP-II asymmetric-energy storage ring facility at the Stanford Linear Accelerator Center. Using approximately 88 million B{bar B} pairs, we measure the decay amplitudes for the flavor eigenmodes and observe strong-phase differences indicative of final-state interactions with a significance of 7.6 standard deviations. We use the interference between the K{pi} S-wave and P-wave amplitudes in the region of the K*(892) to resolve the ambiguity in the determination of these strong phases. We then perform an ambiguity-free measurement of cos 2{beta} using the angular and time-dependent asymmetry in B {yields} J/{psi} K*{sup 0} (K{sub S}{sup 0}{pi}{sup 0}) decays. With sin2{beta} fixed at its measured value and cos2{beta} treated as an independent parameter, we find cos 2{beta} = 2.72{sub -0.79}{sup +0.50}(stat) {+-} 0.27(syst), determining the sign of cos 2{beta} to be positive at 86% CL.

Induced proton polarization for pi^0 electroproduction at Q^2 = 0.126 (GeV/c)^2 around the Delta(1232) resonance  

E-Print Network (OSTI)

We present the first measurement of the induced proton polarization P_n in pi^0 electroproduction on the proton around the Delta resonance. The measurement was made at a central invariant mass and a squared four-momentum transfer of W=1231 MeV and Q^2 = 0.126 (GeV/c)^2, respectively. We measured a large induced polarization, P_n = -0.397 +/- 0.055 +/- 0.009. The data suggest that the scalar background is larger than expected from a recent effective Hamiltonian model.

Observation of f-f' interference in $pi$$sup -$p $Yields$ K$sup -$K$sup +$n at 6 GeV/c  

SciTech Connect

Preliminary results from a study of $pi$$sup -$p $Yields$ K$sup -$K$sup +$n at 6 GeV/c with the Argonne Effective Mass Spectrometer are presented. The 100,000-event data sample shows a dramatic drop in the Y$sub 4$$sup 0$ moment of the K$sup -$K$sup +$ decay angular distribution at a K$sup -$K$sup +$ mass of 1500 MeV. This feature is interpreted as a result of f-f' interference, which can also explain the excess of D-wave cross section near 1450 MeV observed previously. (auth)

Study of Sigma+pi- Invariant Mass spectrum with the KLOE detector; preliminary results and possible hints for Sigma+n internal conversion  

E-Print Network (OSTI)

The AMADEUS collaboration has the goal to perform unprecedented measurements in the field of the low-energy charged kaons-nuclei interactions, by implementing the existing KLOE detector with a dedicated setup in the inner region. As a preliminary step towards the realization, the AMADEUS team has analyzed the existent 2002-2005 KLOE data, studying the processes resulting from the negative kaons nuclear absorption in the entrance wall of the KLOE Drift Chamber (containing mostly carbon) and in the gas filling it, mostly helium. Processes containing Lambda-p and Lambda-d in the final state were looked for, together with the search for the Lambda(1405) going in both the neutral and the charged Sigma-pi channels. These analyses produced unique results, proving the possibility to obtain, for the first time, invariant mass spectra of the Lambda(1405) for all the possible decay channels. This was possible thanks to the unique features of the KLOE detector, including the excellent photon detection of its calorimeter. In addition to these results, other interesting effects like the Sigma->Lambda internal conversion could be investigated. Preliminary results on the Sigma+pi- decay channel and on the Sigma->Lambda internal conversion will be presented.

Crystal Structure of pi Initiator Protein-iteron Complex of Plasmid R6K: Implications for Initiation of Plasmid DNA Replication  

Science Conference Proceedings (OSTI)

We have determined the crystal structure of a monomeric biologically active form of the {pi} initiator protein of plasmid R6K as a complex with a single copy of its cognate DNA-binding site (iteron) at 3.1-{angstrom} resolution. The initiator belongs to the family of winged helix type of proteins. The structure reveals that the protein contacts the iteron DNA at two primary recognition helices, namely the C-terminal {alpha}4' and the N-terminal {alpha}4 helices, that recognize the 5' half and the 3' half of the 22-bp iteron, respectively. The base-amino acid contacts are all located in {alpha}4', whereas the {alpha}4 helix and its vicinity mainly contact the phosphate groups of the iteron. Mutational analyses show that the contacts of both recognition helices with DNA are necessary for iteron binding and replication initiation. Considerations of a large number of site-directed mutations reveal that two distinct regions, namely {alpha}2 and {alpha}5 and its vicinity, are required for DNA looping and initiator dimerization, respectively. Further analysis of mutant forms of {pi} revealed the possible domain that interacts with the DnaB helicase. Thus, the structure-function analysis presented illuminates aspects of initiation mechanism of R6K and its control.

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

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%.

Long-range angular correlations of pi, K and p in p--Pb collisions at sqrt(s_NN) = 5.02 TeV  

E-Print Network (OSTI)

Angular correlations between unidentified charged trigger particles and various species of charged associated particles (unidentified particles, pions, kaons, protons and antiprotons) are measured by the ALICE detector in p-Pb collisions at a nucleon--nucleon centre-of-mass energy of 5.02 TeV in the transverse-momentum range 0.3 trigger particle are obtained in the pseudorapidity range |eta_lab|event multiplicity. In high-multiplicity events, the second-order coefficient for protons, v_2^p, is observed to be smaller than that for pions, v_2^pi, up to about p_T = 2 GeV/c. To reduce correlations due to jets, the per-trigger yield measured in low-multiplicity events is subtracted from that in high-multiplicity events. A two-ridge structure is obtained for all particle species. The Fourier decomposition of this structure shows that the second-order coefficients for pions and kaons are similar. The v_2^p is found to be smaller at low p_T and larger at higher p_T than v_2^pi, with a crossing occurring at about 2 GeV. This is qualitatively similar to the elliptic-flow pattern observed in heavy-ion collisions. A mass ordering effect at low transverse momenta is consistent with expectations from hydrodynamic model calculations assuming a collectively expanding system.

Photons from the decay {pi}{sup 0} {yields} {gamma}{gamma} were detected in the Barrel Electromagnetic Calorimeter of the STAR experiment at the Relativistic Heavy Ion Collider. The {eta} {yields} {gamma}{gamma} decay was also observed and constituted the first {eta} measurement by STAR. The first direct photon cross section measurement by STAR is also presented, the signal was extracted statistically by subtracting the {pi}{sup 0}, {eta}, and {omega}(782) decay background from the inclusive photon distribution observed in the calorimeter. The analysis is described in detail, and the results are found to be in good agreement with earlier measurements and with next-to-leading order perturbative QCD calculations.

Differential cross section and analyzing power of the p-vectorp{yields}pp{pi}{sup 0} reaction at a beam energy of 390 MeV  

Science Conference Proceedings (OSTI)

The differential cross section and analyzing power A{sub y} of the p-vectorp{yields}pp{pi}{sup 0} reaction have been measured at RCNP in coplanar geometry at a beam energy of 390 MeV and the dependence on both the pion emission angle and the relative momentum of the final protons has been extracted. The angular variation of A{sub y} for the large values of the relative momentum studied here shows that this is primarily an effect of the interference of pion s and p waves and this interference can also explain the momentum dependence. Within the framework of a very simple model, these results would suggest that the pion-production operator has a significant long-range component.

5-Ureidobenzofuranone indoles as potent and efficacious inhibitors of PI3 kinase-[alpha] and mTOR for the treatment of breast cancer  

SciTech Connect

A series of 5-ureidobenzofuran-3-one indoles as potent inhibitors of PI3K{alpha} and mTOR has been developed. The best potency in cells was obtained when the urea group was extended to a 4-[2-(dimethylamino)ethyl]methylamino amidophenyl group. A 7-fluoro group on the indole ring also enhanced cellular potency. Compound 18i, incorporating the optimal functional groups, showed high potency in cellular lines and was further studied in vivo. It was able to inhibit the biomarker phosphorylation for 8 h when dosed at 25 mg/kg iv.

A fresh look at $\\eta_{2}(1645), \\eta_{2}(1870), \\eta_{2}(2030)$ and $f_{2}(1910)$ in $\\bar{p}p \\to \\eta^{3}\\pi^{0}$  

E-Print Network (OSTI)

There is a large discrepancy between results of Crystal Barrel and WA102 for the branching ratio R = BR[eta2(1870)->a2(1320)pi]/ BR[eta2(1870)->f2(1270)eta]. An extensive re-analysis of the Crystal Barrel data redetermines branching ratios for decays of eta2(1870), eta2(1645), eta2(2030) and f2(1910). This re-analysis confirms a small value for R of 1.60+-0.39, inconsistent with the value 32.6+-12.6 of WA102. The likely origin of the discrepancy is that the WA102 data contain a strong f2(1910)->a2-pi signal as well as eta2(1870). There is definite evidence that the eta2(1870) has resonant phase variation. A peak in f2(1270)a0(980) confirms closely the parameters of the a2(2255) resonance observed previously. A peak in eta2(2030)-pi is interpreted naturally in terms of pi2(2245) with reduced errors for mass and width M=2285+-20(stat)+-25(syst) MeV, Gamma=250+-20(stat)+-25(syst) MeV.

Experimental evidence for the role of the {pi}{sub CO}* orbital in electron transfer to gas phase acetic acid CH{sub 3}CO{sub 2}H: Effects of molecular orientation  

Science Conference Proceedings (OSTI)

Electron transfer from K atoms to oriented acetic acid molecules produces acetate ions (and K{sup +}) when the CO{sub 2}H end of the molecule is attacked. The electron enters the {pi}{sub CO}* orbital and the donor atom distorts the molecule to allow migration to the {sigma}{sub OH}{sup *} orbital, thereby breaking the bond.

FOURIER TRANSFORM EMISSION SPECTROSCOPY OF THE A {sup 2}{Pi}-X {sup 2}{Sigma}{sup +} (RED) SYSTEM OF {sup 13}C{sup 14}N  

Science Conference Proceedings (OSTI)

Emission spectra of the A {sup 2{Pi}}-X {sup 2}{Sigma}{sup +} transition (red system) of {sup 13}C{sup 14}N have been measured in the 4000-15,000 cm{sup -1} region using the Fourier transform spectrometer associated with the McMath-Pierce Solar Telescope of the National Solar Observatory. The {sup 13}C{sup 14}N free radical was produced in microwave discharge of a mixture of {sup 13}CH{sub 4} and {sup 14}N{sub 2}. Rotational analysis of 22 vibrational bands involving vibrational levels up to v' = 8 and v'' = 5 of the excited and ground states has been obtained and much improved spectroscopic constants have been determined. An experimental line list and calculated term values are provided. The results of the present analysis are useful for the identification of {sup 13}C{sup 14}N lines in late-type stars in the red and near-infrared spectral regions.

In Situ Immobilization of Uranium in Structured Porous Media via Biomineralization at the Fracture/Matrix Interface Subproject to Co-PI Eric E. Roden  

Science Conference Proceedings (OSTI)

Although the biogeochemical processes underlying in situ bioremediation technologies are increasingly well understood, field-scale heterogeneity (both physical and biogeochemical) remains a major obstacle to successful field-scale implementation. In particular, slow release of contamination from low-permeability regions (primarily by diffusive/dispersive mass transfer) can hinder the effectiveness of remediation. The research described in this report was conducted in conjunction with a project entitled In Situ Immobilization of Uranium in Structured Porous Media via Biomineralization at the Fracture/Matrix Interface, which was funded through the Field Research element of the former NABIR Program (now the Environmental Remediation Sciences Program) within the Office of Biological and Environmental Research. Dr. Timothy Scheibe (Pacific Northwest National Laboratory) was the overall PI/PD for the project, which included Scott Brooks (Oak Ridge National Laboratory) and Eric Roden (formerly at The University of Alabama, now at the University of Wisconsin) as separately-funded co-PIs. The overall goal of the project was to evaluate strategies that target bioremediation at interfaces between high- and low-permeability regions of an aquifer in order to minimize the rate of contaminant transfer into high-permeability/high fluid flow zones. The research was conducted at the Area 2 site of the Field Research Center (FRC) at Oak Ridge National Laboratory (ORNL). Area 2 is a shallow pathway for migration of contaminated groundwater to seeps in the upper reach of Bear Creek at ORNL, mainly through a ca. 1 m thick layer of gravel located 4-5 m below the ground surface. Hydrological tracer studies indicate that the gravel layer receives input of uranium from both upstream sources and from diffusive mass transfer out of highly contaminated fill and saprolite materials above and below the gravel layer. We sought to test the hypothesis that injection of electron donor into this layer would induce formation of a redox barrier in the less conductive materials above and below the gravel, resulting in decreased mass transfer of uranium out these materials and attendant declines in groundwater U(VI) concentration. Details regarding the planning, execution, and results of the in situ biostimulation experiment will be provided in separate peer-reviewed publications by the project PIs and colleagues. This report summarizes research activities conducted at The University of Alabama (2002-2005) and the University of Wisconsin (2005-2007) in support of the field experiment, which included (1) chemical and microbiological characterization of sediment cores from Area 2; (2) sediment slurry experiments with Area 2 materials which evaluated the biogeochemical response to ethanol amendment and the potential for U(VI) reduction; (3) analysis of the response of groundwater microbial communities to in situ biostimulation. In addition, biogeochemical reaction models of microbial metabolism in ethanol-stimulated sediments, developed based on sediment slurry experiments, are described.

Transverse Single Spin Asymmetries and Cross-Sections for Forward pi0 and eta Mesons at Large Feynman-x in sqrt(s)=200 GeV polarized p+p Collisions at STAR  

E-Print Network (OSTI)

The STAR collaboration has previously reported a large transverse single spin asymmetry, A_N, for forward pi0 meson production. The cross-section in this region was measured up to Feynman-x (xF) of 0.55, and found to be consistent with perturbative Quantum Chromo-Dynamics predictions. During RHIC running in the year 2006 (6.8 inverse-pb, 56 % average polarization), an even larger A_N was observed for the eta meson at forward rapidity for xF > 0.5. All data were collected by the STAR Forward Pion Detector during sqrt(s) = 200 GeV polarized p+p collisions at RHIC. Understanding these large spin asymmetries requires information on the production cross-section. In this thesis, we present the results of the cross-section as well as the A_N measurements for both pi0 and eta mesons at average pseudo-rapidity of 3.7, for 0.4 high voltage system for the STAR Forward Meson Spectrometer inner calorimeter, which was designed primarily by the author and his thesis advisor.

Global analysis of data on the spin-orbit-coupled A {sup 1{Sigma}}{sub u}{sup +} and b {sup 3{Pi}}{sub u} states of Cs{sub 2}  

SciTech Connect

We present experimentally derived potential curves and spin-orbit interaction functions for the strongly perturbed A {sup 1{Sigma}}{sub u}{sup +} and b {sup 3{Pi}}{sub u} states of the cesium dimer. The results are based on data from several sources. Laser-induced fluorescence Fourier transform spectroscopy (LIF FTS) was used some time ago in the Laboratoire Aime Cotton primarily to study the X {sup 1{Sigma}}{sub g}{sup +} state. More recent work at Tsinghua University provides information from moderate resolution spectroscopy on the lowest levels of the b {sup 3{Pi}}{sub 0u}{sup {+-}} state as well as additional high-resolution data. From Innsbruck University, we have precision data obtained with cold Cs{sub 2} molecules. Recent data from Temple University was obtained using the optical-optical double resonance polarization spectroscopy technique, and finally, a group at the University of Latvia has added additional LIF FTS data. In the Hamiltonian matrix, we have used analytic potentials (the expanded Morse oscillator form) with both finite-difference (FD) coupled-channel and discrete variable representation (DVR) calculations of the term values. Fitted diagonal and off-diagonal spin-orbit functions are obtained and compared with ab initio results from Temple and Moscow State universities.

Branching Fraction for B0 -> pi- l+ nu and Determination of |Vub| in Upsilon(4S) -> B0 B0bar Events Tagged by B0bar -> D(*)+ l- nubar

We report preliminary results from a study of the charmless exclusive semileptonic decay B{sup 0} {yields} {pi}{sup -}{ell}{sup +}{nu} based on the data collected at the {Upsilon}(4S) resonance using the BABAR detector at SLAC. The analysis uses events in which the signal B meson recoils against a B meson that has been reconstructed in a semileptonic decay {bar B}{sup 0} {yields} D{sup (*)+}{ell}{sup -}{bar {nu}}. We extract the total branching fraction {Beta}(B{sup 0} {yields} {pi}{sup -}{ell}{sup +}{nu}) = (1.03 {+-} 0.25{sub stat.} {+-} 0.13{sub syst.}) x 10{sup -4} and the partial branching fractions in three bins of q{sup 2}, the invariant mass squared of the lepton-neutrino system. From the partial branching fractions and theoretical predictions for the form factors, we determine the magnitude of the CKM matrix element |V{sub ub}|. We find |V{sub ub}| = (3.3 {+-} 0.4{sub stat.} {+-} 0.2{sub syst.} {sub -0.4}{sup +0.8}FF) x 10{sup -3}, where the last error is due to normalization of the form factor.

Production of {pi}{sup {+-}}, K{sup {+-}}, K{sup 0}, K*{sup 0}, {phi}, p and {Lambda}{sup 0} in hadronic Z{sup 0} decays  

SciTech Connect

The authors have measured production rates as a function of momentum of the identified hadrons {pi}{sup +}, K{sup +}, K{sup 0}, K*{sup 0}, {phi}, p, {Lambda}{sup 0} and their antihadrons in inclusive hadronic Z{sup 0} decays, as well as separately in decays into light, c and b flavors. In addition they have compared hadron and antihadron production rates in light quark (rather than antiquark) jets. The SLD Cherenkov Ring Imaging Detector was used to identify charged hadrons. The vertex detector was used to tag high-purity samples of light- and b-flavor events. The electron beam polarization was used to tag samples of quark and antiquark jets. Clear flavor dependences are observed, consistent with expectations based upon measured production and decay properties of heavy hadrons. They use the light-flavor results to test the predictions of MLLA QCD and of various fragmentation models. Differences between hadron and antihadron production in light quark jets are observed at high momentum fraction, providing direct evidence that higher-momentum particles are more likely to contain a primary quark or antiquark, and they use these results to make a new direct measurement of strangeness suppression in the jet fragmentation process.

Measurement of single-target spin asymmetries in the electroproduction of negative pions in the semi-inclusive deep inelastic reaction n{up_arrow}(e,e'{pi}{sup -})X on a transversely polarized {sup 3}He target  

SciTech Connect

The experiment E06010 measured the target single spin asymmetry (SSA) in the semiinclusive deep inelastic (SIDIS) n{up_arrow}(e, e'{pi}{sup -})X reaction with a transversely polarized {sup 3}He target as an e#11;ective neutron target. This is the very #12;rst independent measurement of the neutron SSA, following the measurements at HERMES and COMPASS on the proton and the deuteron. The experiment acquired data in Hall A at Je#11;erson Laboratory with a continuous electron beam of energy 5.9 GeV, probing the valence quark region, with x = 0.13 {rt_arrow} 0.41, at Q{sup 2} = 1.31 {rt_arrow} 3.1 GeV{sup 2}. The two contributing mechanisms to the measured asymmetry, viz, the Collins effect and the Sivers effect can be realized through the variation of the asymmetry as a function of the Collins and Sivers angles. The neutron Collins and Sivers moments, associated with the azimuthal angular modulations, are extracted from the measured asymmetry for the very #12;first time and are presented in this thesis. The kinematics of this experiment is comparable to the HERMES proton measurement. However, the COMPASS measurements on deuteron and proton are in the low-x region. The results of this experiment are crucial as the first step toward the extraction of quark transversity and Sivers distribution functions in SIDIS. With the existing results on proton and deuteron, these new results on neutron will provide powerful constraints on the transversity and Sivers distributions of both the u and d-quarks in the valence region.

Branching Fraction Measurements of the Color-Suppressed Decays B0bar to D(*)0 pi0, D(*)0 eta, D(*)0 omega, and D(*)0 eta_prime and Measurement of the Polarization in the Decay B0bar to D*0 omega  

SciTech Connect

We report updated branching fraction measurements of the color-suppressed decays {bar B}{sup 0} {yields} D{sup 0}{pi}{sup 0}, D*{sup 0}{pi}{sup 0}, D{sup 0}{eta}, D*{sup 0}{eta}, D{sup 0}{omega}, D*{sup 0}{omega}, D{sup 0}{eta}', and D*{sup 0}{eta}'. We measure the branching fractions (x10{sup -4}): {Beta}({bar B}{sup 0} {yields} D{sup 0}{pi}{sup 0}) = 2.69 {+-} 0.09 {+-} 0.13, {Beta}({bar B}{sup 0} {yields} D*{sup 0}{pi}{sup 0}) = 3.05 {+-} 0.14 {+-} 0.28, {Beta}({bar B}{sup 0} {yields} D{sup 0}{eta}) = 2.53 {+-} 0.09 {+-} 0.11, {Beta}({bar B}{sup 0} {yields} D*{sup 0}{eta}) = 2.69 {+-} 0.14 {+-} 0.23, {Beta}({bar B}{sup 0} {yields} D{sup 0}{omega}) = 2.57 {+-} 0.11 {+-} 0.14, {Beta}({bar B}{sup 0} {yields} D*{sup 0}{omega}) = 4.55 {+-} 0.24 {+-} 0.39, {Beta}({bar B}{sup 0} {yields} D{sup 0}{eta}') = 1.48 {+-} 0.13 {+-} 0.07, and {Beta}({bar B}{sup 0} {yields} D*{sup 0}{eta}') = 1.49 {+-} 0.22 {+-} 0.15. 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.

Helicity asymmetries in the gamma(pol.) p ---> pi+ pi- reaction  

DOE Green Energy (OSTI)

Beam-helicity asymmetries in the vec gammap ? p?+?- reaction have been measured at Jefferson Lab with the CEBAF Large Acceptance Spectrometer using circularly polarized tagged photons incident on an unpolarized hydrogen target. The experiment covered the resonance region for center-of-mass energies between 1.35 GeV and 2.30 GeV. Here, we show a few examples out of the comprehensive data set and demonstrate the sensitivity of the helicity asymmetries to the dynamics of the reaction by comparing with the results of various phenomenological model calculations.

S S → 3π Written 1996 by T. Nakada (Paul Scherrer Institute) and L. Wolfenstein (Carnegie-Mellon University). The possible final states for the decay K 0 → π + π - π 0 have isospin I = 0, 1, 2, and 3. The I = 0 and I = 2 states have CP = +1 and K S can decay into them without violating CP symmetry, but they are expected to be strongly suppressed by centrifugal barrier effects. The I = 1 and I = 3 states, which have no centrifugal barrier, have CP = -1 so that the K S decay to these requires CP violation. In order to see CP violation in K S → π + π - π 0 , it is necessary to observe the interference between K S and K L decay, which determines the amplitude ratio η +-0 = A(K S → π + π - π 0 ) A(K L → π + π - π 0 ) . (1) If η +-0 is obtained from an integration over the whole Dalitz plot, there is no contribution from the I = 0 and I = 2 final states and a nonzero value of η +-0 is entirely due to CP violation. Only I = 1 and I = 3

A new proposal to measure K^+ -> pi^+ nu nubar  

SciTech Connect

For an experimentalist in high energy physics, the most interesting experiments that one should pursue is often well known. The very rare CP violating decay of the kaon into a pion and two neutrinos (both the charged and neutral modes ) is such an experiment. We have recently proposed the charged kaon experiment to Fermilab as proposal P966. We present her a general overview of that proposal. The goal is to obtain of order 1000 events in order to confront the expected theoretical calculations and to search for physics beyond the standard model.

DISCUSSION PAPER PI-0607 Risk Measures and Comonotonicity: a Review  

E-Print Network (OSTI)

In this paper we examine and summarize properties of several well-known risk measures that can be used in the framework of setting solvency capital requirements for a risky business. Special attention is given to the class of (concave) distortion risk measures. We investigate the relationship between these risk measures and theories of choice under risk. Furthermore we consider the problem of how to evaluate risk measures for sums of non-independent random variables. Approximations for such sums, based on the concept of comonotonicity, are proposed. Several examples are provided to illustrate properties or to prove that certain properties do not hold. Although the paper contains several new results, it is written as an overview and pedagogical introduction to the subject of risk measurement. The paper is an extended version of Dhaene et al. (2003). 1

Final Scientific/Technical Report DE-FG02-06ER64172 Reaction-Based Reactive Transport Modeling of Iron Reduction and Uranium Immobilization at Area 2 of the NABIR Field Research Center Subproject to Co-PI Eric E. Roden  

Science Conference Proceedings (OSTI)

This report summarizes research conducted in conjunction with a project entitled Reaction-Based Reactive Transport Modeling of Iron Reduction and Uranium Immobilization at Area 2 of the NABIR Field Research Center, which was funded through the Integrative Studies Element of the former NABIR Program (now the Environmental Remediation Sciences Program) within the Office of Biological and Environmental Research. Dr. William Burgos (The Pennsylvania State University) was the overall PI/PD for the project, which included Brian Dempsey (Penn State), Gour-Tsyh (George) Yeh (Central Florida University), and Eric Roden (formerly at The University of Alabama, now at the University of Wisconsin) as separately-funded co-PIs. The project focused on development of a mechanistic understanding and quantitative models of coupled Fe(III)/U(VI) reduction in FRC Area 2 sediments. The work builds on our previous studies of microbial Fe(III) and U(VI) reduction, and was directly aligned with the Scheibe et al. ORNL FRC Field Project at Area 2. Area 2 is a shallow pathway for migration of contaminated groundwater to seeps in the upper reach of Bear Creek at ORNL, mainly through a ca. 1 m thick layer of gravel located 4-5 m below the ground surface. The gravel layer is sandwiched between an overlying layer of disturbed fill material, and 2-3 m of undisturbed shale saprolite derived from the underlying Nolichucky Shale bedrock. The fill was put in place when contaminated soils were excavated and replaced by native saprolite from an uncontaminated area within Bear Creek Valley; the gravel layer was presumably installed prior to addition of the fill in order to provide a stable surface for the operation of heavy machinery. The undisturbed saprolite is highly weathered bedrock that has unconsolidated character but retains much of the bedding and fracture structure of the parent rock (shale with interbedded limestone). Hydrological tracer studies conducted during the Scheibe et al. field project indicate that the gravel layer receives input of uranium from both upstream sources and from diffusive mass transfer out of highly contaminated fill and saprolite materials above and below the gravel layer. This research sought to examine biogeochemical processes likely to take place in the less conductive materials above and below the gravel during the in situ ethanol biostimulation experiment conducted at Area 2 during 2005-2006. The in situ experiment in turn examined the hypothesis that injection of electron donor into this layer would induce formation of a redox barrier in the less conductive materials, resulting in decreased mass transfer of uranium out these materials and attendant declines in groundwater U(VI) concentration. Our research was directed toward the following three major objectives relevant to formation of this redox barrier: (1) elucidate the kinetics and mechanisms of reduction of solid-phase Fe(III) and U(VI) in Area 2 sediments; (2) evaluate the potential for long-term sustained U(IV) reductive immobilization in Area 2 sediments; (3) numerically simulate the suite of hydrobiogeochemical processes occurring in experimental systems so as to facilitate modeling of in situ U(IV) immobilization at the field-scale.

The influence of anion-pi interactions between multi-atomic anions and pi-acidic ring systems on the self-assembly of coordination compounds  

E-Print Network (OSTI)

Anion-? interactions, weak attractions between anions and ?-acidic ring systems, have become an important topic in supramolecular chemistry within the past five years. Although a variety of computational studies have been undertaken by several groups to investigate the nature of these interactions, no comprehensive experimental investigations had been performed until the completion of the work described herein. The results presented in this dissertation indicate that anion-? interactions involving large complex anions are controlling elements in self-assembly reactions with cations that involve ?-acidic ring systems. Syntheses performed with the ligand 3-6-bis(2-pyridyl)-1,2,4,5-tetrazine, or bptz, with M(II) first row transition metal salts (M = Mn, Fe, Ni, Cu, and Zn), produced self-assembled complexes that varied in shape and M:ligand ratio based on the presence of particular anions. Through a series of solution and structural studies, it was determined that the cationic polygons are templated by the size and shape of the specific anions during self-assembly. A close inspection of the bptz complexes in the solid state indicated that the anions were participating in anion-? interactions with the ?-acidic central tetrazine ring of the ligand. To show that these anion-? interactions were indeed important, reactions of bptz ligand as well with 3,6-bis(2-pyridyl)-1,2-pyridazine (bppn) with Ag(I) salts were performed to compare the effect that specific anions had on self-assembly interactions between similar ligands with different ?-acidities. The results indicate that the Ag(I) complexes that included the ?-acidic tetrazine ring are strongly influenced by the anion presence, while those complexes that were synthesized with the similarly shaped, but electroneutral bppn ligand only relied on the anions for charge-balance. To better understand the anion-? interactions in the obtained bptz complexes, a computational study was performed on systems with the polyatomic anions [BF4]- and [PF6]- interacting with simple heteroaromatic rings of varying degrees of ?-acidity. Based on the final optimized complex geometries and Atoms in Molecules (AIM) critical point analyses, it was determined that anion-? interactions involving multiatomic anions interact with ?-systems in different orientations based on the symmetry of the ring system in the complex.

The Molecular Interaction of CAR and JAML Recruits the Central Cell Signal Transducer PI3K  

Science Conference Proceedings (OSTI)

Coxsackie and adenovirus receptor (CAR) is the primary cellular receptor for group B coxsackieviruses and most adenovirus serotypes and plays a crucial role in adenoviral gene therapy. Recent discovery of the interaction between junctional adhesion molecule-like protein (JAML) and CAR uncovered important functional roles in immunity, inflammation, and tissue homeostasis. Crystal structures of JAML ectodomain (2.2 angstroms) and its complex with CAR (2.8 angstroms) reveal an unusual immunoglobulin-domain assembly for JAML and a charged interface that confers high specificity. Biochemical and mutagenesis studies illustrate how CAR-mediated clustering of JAML recruits phosphoinositide 3-kinase (P13K) to a JAML intracellular sequence motif as delineated for the {alpha}{beta} T cell costimulatory receptor CD28. Thus, CAR and JAML are cell signaling receptors of the immune system with implications for asthma, cancer, and chronic nonhealing wounds.

Neutral strange particle production in $pi$ tau interactions at 250 GeV/c  

SciTech Connect

Neutral strange particles were studied in about one third of a 46,000 picture exposure of 250-GeV/c pions in the Fermilab 15 foot bubble chamber. This chamber is particularly well suited for the study of neutral particles because of its large volume. Experimental inclusive cross sections are sigma (K/sub s/$sup 0$) equals 4.17 +- 0.45 mb, sigma (LAMBDA$sup 0$) = 1.74 +- 0.24 mb, sigma (anti LAMBDA$sup 0$) = 0.82 +- 0.13 mb. The average number of K/sub s/$sup 0$, LAMBDA$sup 0$, anti LAMBDA$sup 0$ per inelastic collision are approximately independent of charge multiplicity. F$sub 1$(x) and F$sub 2$(p/sup 2// sub t/) distributions as well as two strange particle mass plots are presented. (auth)

Final Report for: "Bis-pi-allylpalladium Complexes in Catalysis of Multicomponent Reactions"  

Science Conference Proceedings (OSTI)

The research project involved the development of new and functionally improved Pd(II) catalyst for a three-component reaction of boronic acids, allenes and imines to afford homoallylic amines that are useful in synthesis of biologically active heterocycles. Furthermore, insights into the reaction mechanism and the structure and reactivity of the catalytically active intermediates involved in this process were sought. As a result of this work, a new type of Pd-catalysts possessing an auxiliary ligand attached to the Pd center via a C-Pd and N-Pd bonds were identified, and found to be more active than the traditional catalysts derived from Pd(OAc)2. The new catalysts provided an access to a broader range of homoallylic amine products. Although the final unequivocal evidence regarding the structure of the Pd(II) complex involved in the nucleophilic transfer of the allyl fragment from the palladium center to the imine could not be obtained, mechanistic insights into the events that are detrimental to the activity of the originally reported Pd(OAc)2-based catalytic systems were uncovered.

Toward a Modal Theory of Types for the Pi-Calculus  

E-Print Network (OSTI)

We study the problem of specifying and verifying properties of -calculus processes while relying on a bisimulation semantics. As our property specification language we use a version of the modal -calculus adapted to the -calculus. We show that the logical language is sufficiently expressive to characterize by means of a finite formula a process up to any approximation of the bisimulation relation. We consider the problem of checking that a process of the -calculus satisfies a specification expressed in this modal -calculus. We develop an algorithm which is sound in general, and complete for processes having a finite reachability property. Finally, we present a proof system which can be applied to prove non-recursive properties of arbitrary processes. We show that the system is complete on the non-recursive fragment of the logical language. 1 Introduction The -calculus was introduced by Milner, Parrow, and Walker [MPW92] as a language for describing concurrent systems with feat...

Exciton and biexciton signatures in femotosecond transient absorption of {pi}-conjugated oligomers  

Science Conference Proceedings (OSTI)

The authors report femotosecond transient-absorption studies of a five-ring oligomer of polyphenylenevinylene (PPV) prepared in two different forms: as solid-state films and dilute solutions. Both types of samples exhibit a photoinduced absorption (PA) band with dynamics which closely match those of the stimulated emission (SE), demonstrating unambiguously that these features originate from the same species, namely from intrachain singlet excitons. Photo-chemical degradation of the solid-state samples is demonstrated to dramatically shorten the SE dynamics above a moderate incident pump fluence, whereupon the dynamics of the SE and the long-wavelength PA no longer coincide. In contrast to solutions, solid-state films exhibit an additional short-wavelength PA band with pump-independent dynamics, indicating the efficient formation of non-emissive inter-chain excitons. Correlations in the subpicosecond dynamics of the two PA features, as well as the pump intensity-dependence provide strong evidence that the formation of inter-chain excitons is mediated by intrachain two-exciton states. At high pump levels, the authors see a clear indication of interaction between excited states also in dilute solutions. This is manifested as a superlinear pump-dependence and shortening of the decay dynamics of the SE. They attribute this behavior to the formation of biexcitons resulting from coherent interaction between two excitons on a single chain.

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.

{pi} and {sigma} mesons at finite temperature and density in the Nambu-Jona-Lasinio model with dimensional regularization  

SciTech Connect

Dynamical symmetry breaking and meson masses are studied in the Nambu-Jona-Lasinio model at finite temperature and chemical potential using dimensional regularization. Since the model is not renormalizable in four space-time dimensions, physical results and parameters depend on the regularization method. Following the imaginary-time formalism, we introduce the temperature T and the chemical potential {mu}. The parameters of the model are fixed by calculating the pion mass and decay constant in dimensional regularization at T={mu}=0.
