Multiparticle Production on Hydrogen, Argon and Xenon Targets in a Streamer Chamber by 200-GeV/c Proton and anti-Proton Beams

Interactions of 200-GeV protons and antiprotons on hydrogen, argon, and xenon targets were studied with a streamer-chamber vertex spectrometer at the CERN SPS. Results on multiplicities, rapidity distributions, and correlations are presented and compared with predictions of current models.
