Antiproton distributions in Au+nucleus collisions
1997
Experiment E878 at the BNL-AGS has measured the invariant cross sections of antiprotons produced near p{sub t}=0 in interactions of 10.8 GeV/c Au beams with targets of Al, Cu, and Au. The data were measured for a wide range of centralities and rapidities using a focusing beamline spectrometer and a high-rate centrality detector. We compare our data with the predictions of simple models and sophisticated transport models to explore the physics of antiproton production and annihilation. {copyright} {ital 1997} {ital The American Physical Society}
