  • During the period of this contract, the participants carried out theoretical and experimental researches in high energy particle physics. The experiment group has been working with both bubble chamber and electronic detectors. The bubble chamber work made use of bubble chambers and particle beams at Lawrence Berkeley Laboratory, Brookhaven National Laboratory, Fermilab, and the Stanford Linear Accelerator Center. The different electronic detectors were the TPC/Two Gamma facility situated at the PEP electron-positron collider at SLAC, the AMY detector at TRISTAN, the electron-positron collider at KEK in Japan, fixed target detectors at Fermilab, and a hybrid bubble chamber/electronic detector at SLAC.more » Negotiations were also started with the H1 collaboration for a UCD participation at the upcoming Hera electron-proton collider. The theoretical groups have been engaged in a wide variety of studies. Phenomenological studies of high energy interactions have constituted a major fraction of the effort, particularly those associated with the higgs field, various aspects of supersymmetry, and searches for new physics. Work on reactions associated with ee, ep, and hadron colliders has been extensive and includes many analyses providing tests of QCD. Lattice gauge theory has been a major area of work, and electroweak physics and mathematical physics have also been topics of study. Work has been published on heavy flavor decays and CP noninvariance, super symmetry, Yang-Mills theory and electroweak symmetry breaking as well as string theory.« less

Lattice gauge calculations on finite temperature phase transitions have also been under study, as well as work on string theory.« less
  • During the period covered by this report, the experimental group: (1) fabricated a set of drift chambers for the muon detector part of the PEP-9 apparatus; (2) completed data taking at SLAC in a search for narrow four-quark resonant states and began the analysis of the photos; (3) developed software for PEP-9 off-line analysis and Monte Carlo programs; (4) continued data taking at Fermilab for K/sup 0/ production studies; and (5) finished drafting several papers that will conclude our bubble chamber studies of ..pi../sup -/d interactions.
