High energy physics studies. Progress report for Task B

PDF Version Also Available for Download.

Description

Task B is involved in a unified program investigating charmed quark physics in two different, yet related accelerator experiments. The first of these is Fermilab Experiment E760, a high resolution study of the formation of charmonium states in proton-antiproton interactions. E760, which is actively running at the present time, has already produced results adding significantly to knowledge of the properties of several charmonium states, and is engaged in an important search for new states which cannot be formed in electron-positron collisions. The second experiment, which the Task B Group has joined during the past year, is an intensive study of ... continued below

Description

Task B is involved in a unified program investigating charmed quark physics in two different, yet related accelerator experiments. The first of these is Fermilab Experiment E760, a high resolution study of the formation of charmonium states in proton-antiproton interactions. E760, which is actively running at the present time, has already produced results adding significantly to knowledge of the properties of several charmonium states, and is engaged in an important search for new states which cannot be formed in electron-positron collisions. The second experiment, which the Task B Group has joined during the past year, is an intensive study of charmonium and charmed mesons using electron-positron collisions in the BEijing Spectrometer (BES) at the Beijing Electron Positron Collider (BEPC). This is a collaboration between several universities in the United States, SLAC and the Institute of High Energy Physics in Beijing. Work on one of the group`s previous projects, a search for baryonium states in proton-antinucleon interactions at the Low Energy Antiproton Ring (LEAR) at CERN, was completed during the past contract year, and final papers reporting results have been submitted for publication. The entire Task B Group is participating in the E760 project at Fermilab. Although the UCI group`s primary responsibility has been the design, construction, calibration, installation and operation of the lead glass Central Calorimeter, which is the principal component of the detector, the group has participated significantly in all facets of the preparation, installation and running of the experiment. These activities have included work on the development of the data acquisition system, trigger design, software development and code management, participation in beam deceleration and beam operation during running, and data analysis on a variety of channels.
