Proton production from Si+Au collisions at 14.5 A-GeV

Abstract Recent results are presented from the study of central Si+Au → p+X, Si+Au → π ± +X, and Si+Cu → p+X at 14.5 A.GeV. The distribution of protons in rapidity indicates that many target protons are found above 0.5 units. The variation of the slope parameter in rapidity is consistent with a thermal source of protons at the geometric center-of-mass rapidity.
