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

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, &lt;(Lambda)over bar&gt;, Xi(-) and &lt;(Xi)over bar&gt;(+) 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
