Abstract

Strange and multistrange hyperon production is expected to be enhanced in heavy ion interactions if a phase transition from hadronic matter to a quark-gluon plasma takes place. The production yields of Lambda s, <(Lambda)over bar>s, Xi(-)s, and <(Xi)over bar>(+)s relative to the production of negative particles are presented for p-W, p-S, S-W, and S-S interactions at 200 GeV/c per nucleon and compared to those from p-Pb and Pb-Pb interactions at158 GeV/c per nucleon. In particular, enhancements of strange and multistrange hyperons will be presented where hyperon yields are normalized to the yields of negative particles.
