We have measured π ±, K±, P and P spectra from proton and sulfur collisions with nuclear targets at the at beam energies of 450 Gev and 200 Gev per nucleon respectively. For central SA collisions we see that kaons and (anti)protons have large transverse energies. Protons are moved into central rapidity by rescattering where they annhilate antiprotons. The RQMD event generator qualitatively reproduces these trends while Fritjof does not.
