Multiparticle production on hydrogen, argon, and xenon targets in a streamer chamber by 200-GeV/<i>c</i>proton and antiproton beams

Interactions of 200-GeV/c 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.
