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

Abstract 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 identificationhas 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 massspectra for π ± , K ± and p( p ) at central rapidity and p T > 1.3 GeV/ c are presented.
