Anti-proton distributions in Au + nucleus collisions

Experiment E878 at the BNL-AGS has measured the invariant cross sections of antiprotons produced near pt=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.

nucleus nucleus: inclusive reaction
gold
aluminum
copper
anti-p: production
anti-p: yield
transverse momentum: low
