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 at 158 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.

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 at 158 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.File in questo prodotto:
