Abstract

The transverse momentum and rapidity distributions of negative hadrons and participant protons have been measured for central S32+ S32 collisions at plab=200 GeV/c per nucleon. The proton mean rapidity shift Δy∼1.6 and mean transverse momentum pT∼0.6 GeV/c are much higher than in pp or peripheral AA collisions and indicate an increase in the nuclear stopping power. All pT spectra exhibit similar source temperatures. Including previous results for Ks0 Λ, and Λ̄, we account for all important contributions to particle production.
