Investigations on Baryonium and Other Rare p Anti p Annihilation Modes Using High-Resolution pi sup 0 Spectrometers (PS182)

摘要

Topics include the gamma-ray spectrum associated with the p anti p annihilation, some easily detectable possible decay channels of baryonium, and the direct production of gamma-rays in the normal annihilation process. Topics covered include the proposed physics, the detector system, and count rate problems. The high anti p flux of the Low-Energy Antiproton Ring (LEAR) will result in a correspondingly high trigger rate. The search for exotic states below the p anti p threshold has yielded a few candidates for such states, as supported by experiments on the CERN Proton Synchrotron (PS) conducted by the Basel-Karlsruhe-Stockholm-Strasbourg-Thessaloniki Collaboration.
