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
