  • Since the beginning of the ERDA contract year (Dec. 1, 1976), the Indiana High Energy Physics Group has been actively participating in experimental programs at SLAC, Fermilab, CERN, and the Argonne ZGS. The SLAC effort (E103) is a search for exotic mesons. The polarization program at Fermilab's internal target (CO) area involves polarization measurements in pp ..-->.. pp (E313) and pp ..-->.. pX (E522). The contribution to the Multiparticle Spectrometer at Fermilab is a major ingredient in a series of experiments (E110/260/523/557) studying low-p/sub t/ and high-p/sub t/ hadron-hadron collisions. At CERN work is carried out with a Saclay groupmore » at the SPS to investigate properties of psi meson production in experiment WAll. The Argonne ZGS endeavor (E399) is to measure various inclusive polarizations, complementing Fermilab E522 work. Also participation is given in design work on a PEP proposal. A discussion of these experiments is given.« less
  • The University of Pennsylvania elementary particle physics/particle cosmology group, funded by the Department of Energy Office of Science, participates in research in high energy physics and particle cosmology that addresses some of the most important unanswered questions in science. The research is divided into five areas. Energy Frontier - We participate in the study of proton-proton collisions at the Large Hadron Collider in Geneva, Switzerland using the ATLAS detector. The University of Pennsylvania group was responsible for the design, installation, and commissioning of the front-end electronics for the Transition Radiation Tracker (TRT) and plays the primary role in its maintenancemore » and operation. We play an important role in the triggering of ATLAS, and we have made large contributions to the TRT performance and to the study and identification of electrons, photons, and taus. We have been actively involved in searches for the Higgs boson and for SUSY and other exotic particles. We have made significant contributions to measurement of Standard Model processes such as inclusive photon production and WW pair production. We also have participated significantly in R&D for upgrades to the ATLAS detector. Cosmic Frontier - The Dark Energy Survey (DES) telescope will be used to elucidate the nature of dark energy and the distribution of dark matter. Penn has played a leading role both in the use of weak gravitational lensing of distant galaxies and the discovery of large numbers of distant supernovae. The techniques and forecasts developed at Penn are also guiding the development of the proposed Large Synoptic Survey Telescope (LSST).We are also developing a new detector, MiniClean, to search for direct detection of dark matter particles. Intensity Frontier - We are participating in the design and R&D of detectors for the Long Baseline Neutrino Experiment (now DUNE), a new experiment to study the properties of neutrinos. Advanced Techology R&D - We have an extensive involvement in electronics required for sophisticated new detectors at the LHC and are developing electronics for the LSST camera. Theoretical Physics - We are carrying out a broad program studying the fundamental forces of nature and early universe cosmology and mathematical physics. Our activities span the range from model building, formal field theory, and string theory to new paradigms for cosmology and the interface of string theory with mathematics. Our effort combines extensive development of the formal aspects of string theory with a focus on real phenomena in particle physics, cosmology and gravity.« less

  • Research can be divided into two categories, the first dealing with the phenomenological treatment of two-body collisions, and the second dealing with symmetry-breaking and charm within the framework of the quark model. A partial-wave amplitude analysis of ..pi../sup +/ proton elastic scattering at incident pion momenta between 1.6 GeV/c and 10 GeV/c has been made. The partial wave amplitudes agree with those at lower momenta and are close to the Regge amplitudes at higher momenta. A number of new resonances are suggested. Also high energy proton-proton scattering was analyzed using Reggeon field theory and a bare pomeron intercept abovemore » unity. Furthermore, high energy pion-nucleon charge-exchange data were described by including absorptive corrections to a rho Reggeon exchange. In the second category, meson mass spectra, including predicted masses of charmed mesons, in the quark model using attractive 1/r plus linear confining potentials. The quark model was used to obtain relations among electromagnetic mass splittings of mesons, including charmed mesons, to calculate the pion form factor, and to obtain magnetic moments of baryons. Also restrictions on a quark potential with confinement were discussed in order to obtain linear Regge trajectories. A list of publications is included.« less
  • Research during the past year covers a wide range of topics, and includes work on analyzing particle collisions, meson spectra from quark interactions, and gauge fields; work was done closely with several high energy experimental groups. An extensive partial wave analysis of pion-nucleon scattering up to 10 GeV/c was completed revealing many new high spin baryon resonances which correspond to high quark excitations. A one-gluon-exchange potential with linear confinement was examined to study mass spectra, with particular attention being paid to the latest interesting structures around 3.772 GeV at SLAC and 9.5 GeV at FNAL. In gauge fields, success wasmore » found in deriving several rigorous results dealing with Wilson's gauge theory on a lattice. Throughout the year, there was a continuation of work in close collaboration with experimentalists, not only at Indiana, but also at Iowa State and Argonne. Lastly in May, help was given to organize a two-day conference on the present status of weak interactions. A list of publications is presented.« less
