Study of charged particle production using Omega RICH in WA94 experiment

Abstract We present preliminary results about charged particle production in SS collisions at 200 GeV/ c per nucleon, obtained by WA94 experiment at CERN-SPS. The particle identification has been provided by the Omega RICH; a silicon telescope and an array of multiwire proportional chambers (MWPC) have been used to track particles to the RICH detector. Details about particle tracking and identification procedure are also reported.
