Differences betweenp¯pandppinteractions at 8.8 GeV/cand their relationship top¯pannihilations

Abstract
We report on an experiment in which the SLAC 40-in. hybrid facility was exposed to an 8.8-GeV/c antiproton beam. Using external detectors we have identified a large fraction of nonannihilation events and thus obtained a clean sample of annihilation data. Using proton interactions taken in the same detector at the same energy we have made a detailed study of (p¯ppp) differences and explored their relationship to p¯p annihilations.
