Enhancement of strange and multi-strange hyperons and anti-hyperons in S-S and S-W interactions at 200 GeV/c

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, s, Xi(-)s, and (+)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

Charged particle production in S-S collisions at 200 GeV/c per nucleon

Charged particle production in central S-S collisions at 200 GeV/c per nucleon has been studied by the WA94 experiment at the CERN-SPS. Particle identification has been provided by the Omega RICH, while a silicon telescope in the Omega spectrometer and an array of MultiWire Proportional Chambers have been used to trace particles through the RICH detector. Production ratios and transverse mass spectra for pi(+/-), K+/- and p((p) over bar) at central rapidity and p(T) > 1.3 GeV/c are presented. (C) 1997 Elsevier Science B.V

Hyperon production in proton-sulphur collisions at 200 GeV/c

The WA94 experiment uses the production of strange particles and antiparticles to investigate the properties of hot hadronic matter created in heavy-ion interactions. Lambda, , Xi(-) and (+) particle yields and transverse mass spectra are presented for pS interactions. These results are compared with those from SS interactions. Our results are also compared with those from pW and SW interactions of the WA85 experiment. (C) 1997 Published by Elsevier Science B.V

STRANGE PARTICLE-PRODUCTION IN SULFUR-SULFUR INTERACTIONS AT 200 GEV/C PER NUCLEON

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 less than or equal to p(T) less than or equal to 3.0 GeV/c and 2.5 less than or equal to y(lab) less than or equal to 3.0, and m(T) spectra for Lambda, , Xi(-) and (-) particles are presented. Preliminary results on charged kaon production are also discussed, together with the: status of charged particle identification using the Omega RICH
