This book was released on 1994 with total page 151 pages. Available in PDF, EPUB and Kindle. Book excerpt: Task A involves the study of kaon decays. The overall physics focus of the current work is rare and semi-rare decays of the? and the short-lived kaon, with an emphasis on those aspects needed in preparation for the proposed?-factory measurements of CPT violation. Another aspect of the rare kaon decay work is E865 at BNL, a search for K yields?+?+e−, a lepton number violating process. Pittsburghs̀ E865 responsibilities are the design and construction of the Cerenkov counters. The major goals of task B are as follows: (1) the analysis of the E706 (direct photon production) data taken during the 1987--1988 and 1990--1991 target runs at Fermilab and (2) the continuation of work within SVXII group of the CDF collaboration. The CDF program involves a dedicated effort towards the design of the silicon vertex detector upgrade, SVXII.

This book was released on 1993 with total page 215 pages. Available in PDF, EPUB and Kindle. Book excerpt: During the past year on Task A, the HELIOS work drew to a close with first results from the electron-muon pair studies (no anomalous sources are seen, and the final results and uncertainties are being set). First data from CMD2 will allow improvement of some phi branching ratios, including some improved limits on forbidden decays. The engineering run for E865 is scheduled for June and July of 1993. The principal efforts of Task B, the Fermilab program, have been the completion of the analysis of the 1987--88 data with resulting publications, completion of the 1990--91 data run, and the beginning of the analysis of the 1990--91 data. In addition, the Task B group is taking a leadership role in developing a proposal to Fermilab for the upgrade of the CDF silicon vertex detector in preparation for the 1995 data run. Task C has recently submitted results of its fractionally charged particle searches, placing new upper limits on the abundance of naturally-occurring fractionally-charged particles in various materials. This group has recently been approved by the Brookhaven management for an exposure of their p-i-n diodes in a high intensity proton beam. This measurement, along with its subsequent analysis, will complete the program. Task D concerned itself with silicon drift chamber studies for the SSC. Task E was devoted to studies of electronics for the GEM Level 1 liquid Ar calorimeter trigger.

This book was released on 1992 with total page 87 pages. Available in PDF, EPUB and Kindle. Book excerpt: During the past year Task A completed the HELIOS single and pair electron analyses and found no anomalous production or multiplicity dependence. The HELIOS electron-muon pair analysis continued in its search for lepton physics beyond the expected charm yields. Data taking began at the CMD2 detector at Novosibirsk. Measurements of the U.V. reflectivity and photomultiplier tests for the first Cerenkov counter to be used in the E865 experiment at BNL were carried out, along with the development of a general ray-tracing code. The design of the Cerenkov counter for E865 along with development of light mirror fabrication techniques were a major part of the Task A program. The principal efforts of Task B, the Fermilab program, have been the completion of the analysis of the 1987--1988 data with resulting publications, completion of the 1990--1991 data run, and the beginning of the analysis of the 1990--1991 data. In addition, the Task B group is taking a leadership role in developing a proposal to Fermilab for the upgrade of the CDF silicon vertex detector in preparation for the 1995 data run. This proposal is to be presented to the laboratory management in time for the fall Fermilab Program Advisory Committee meeting. Task C has recently submitted results of its fractionally charged particle searches, placing new upper limits on the abundance of naturally-occurring fractionally-charged particles in various materials. This group has recently been approved by the Brookhaven management for an exposure of their p-i-n diodes in a high intensity proton beam.

Available in PDF, EPUB and Kindle. Book excerpt: The Brandeis experimental particle physics group has for many years pursued an understanding of physical interactions at the highest available energies. To this end they have been active in the development of the Collider Detector at Fermilab (CDF) and in the development of detectors that were planned for the SSC. They have also had an active program of analysis to understand the data and its implications from these detectors. Brandeis remains fully engaged in the understanding of physical interactions at the highest available energies. While pursuing physics analysis, detector support activities and detector upgrades at CDF, they are also exploring the physics potential of the LHC. Pending overall agreements between the Department of Energy and CERN, the authors have joined the ATLAS experiment at CERN. The expertise gained in planning SSC detectors is directly applicable there. During the past year, the theoretical physics group pursued research in quantum field theory, with the 1/N expansion and other non-perturbative methods providing a unifying theme of much of this work. Activities centered on large N limit in scalar field theories, and two-dimensional Yang-Mills theories.

The effort has now moved to investigating the physics derived from the √s = 4.03 GeV data, including D{sub s} production, absolute D{sub s} branching fractions (hadronic, leptonic, and inclusive semileptonic), D*D and D*D* production, absolute D hadronic branching fractions, D* branching fractions, and an upper limit on the [nu]{sub {tau}} mass. 2 figs., 11 refs.

Available in PDF, EPUB and Kindle. Book excerpt: The University of Texas at Dallas (UTD) is participating in two ee−, experiments, Beijing Spectrometer (BES) and BABAR, the PEP-11 B Factory detector. The UTD group consists of Profs. Joseph M. Izen and Xinchou Lou, seven Ph. D. students. A post-doc is requested to join them in this work. BES explores the physics of the?-charm threshold region. Associated production of? and charmed mesons allow for absolute branching fraction measurements with good control of backgrounds. BES is uniquely positioned to study the leptonic and hadronic decays of quarkonia. The Beijing Electron Positron Collider (BEPC) delivers luminosities an order of magnitude higher than earlier facilities. BES and BEPC will be upgraded following the 1994-5 run, and will resume data taking in Fall, 1996 with an improved detector and a Three-fold increase in luminosity. The raison dètre of BABAR is the exploration of CP violation in the B meson system. An asymmetric storage ring is required to observe the time-dependence of the CP asymmetry. Other BABAR physics includes measurements of CKM matrix elements, rare B decays, penguin diagrams, B{sub s} decays, and precision measurements of? and D meson decays. The scheduled BABAR turn-on in 1999 provides the UTD group with a natural evolution with continuous physics during this period. Professors Joseph M. Izen and Xinchou Lou are leading the BES and BABAR program at UTD. Both have specialized in e+e− collider experiments and share 22 years of experience at the SPEAR, BEPC, CESR, PETRA, SLC and LEP rings.
