Strange particle production in sulphur-sulphur interactions at 200 GeV/c per nucleon

Abstract The WA94 experiment is designed to study the production of strange and multistrange baryons and antibaryons at central rapidity in sulphur-sulphur interactions at 200 GeV/c per nucleon. Particle production ratios have been obtained in the kinematic region 1.2 ≤ p T ≤ 3.0 GeV/ c and 2.5 ≤ y lab ≤ 3.0, and m T spectra for Λ, Λ , Ξ − and Ξ − particles are presented. Preliminary results on charged kaon production are also discussed, together with the status of charged particle identification using the Omega RICH.
