PROPOSAL TO SEARCH FOR ANTIPROTON DECAY AT THE FERMILAB ANTIPROTON ACCUMULATOR

We propose to search for antiproton decay at the Fermilab antiproton accumulator. The experiment would search for decay modes in which there is an e-or~-in the final state, and would be optimized to search for the decay mode p-4 e-+ xO. We expect to achieve an experimental sensitivity to'tp x BR (p-4 e-+ n; o) of up to 0 (108 years), which is an improvement of 8 orders of magnitude over existing laboratory searches. t Spokesperson
