Multiparticle Production by 200-GeV/c Hadrons on Gold, Silver, and Magnesium Targets

We have used the Fermilab 30-in. bubble-chamber hybrid spectrometer to study multiparticle production in the interactions of 200-GeV/c protons and π+ and K+ mesons with nuclei of gold, silver, and magnesium. We find that the multiplicities of produced particles and negative particles increase linearly with the number of projectile collisions, with no beam or target dependence. The number of secondary collisions in the nucleus increases significantly less rapidly with the number of projectile collisions than has been reported by a streamer chamber experiment. The properties of secondary collisions suggest that they arise from rescattering of recoil nucleons rather than intranuclear cascade of produced particles. Dispersions of multiplicity distributions at fixed impact parameter are in better agreement with a model of independent sources than with Koba-Nielsen-Olesen scaling.

Production of neutral strange particles in p Ar, p Xe and anti-p Xe collisions at 200-GeV

Derado, I. ; Kadija, K. ; Malecki, M. ; et al.
Z.Phys.C 50 (1991) 31-36, 1991.
Inspire Record 28958 DOI 10.17182/hepdata.15007

The production of neutral strange particles (K0, Λ) inp Ar,pXe and\(\bar p\)Xe collisions at 200 GeV is investigated in the NA5 experiment using a streamer chamber at the CERN SPS. Results are presented on inclusive cross sections, average multiplicities, and on rapidity and transverse momentum distributions of neutral strange particles.

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.

MEASUREMENT OF THE AVERAGE TRANSVERSE MOMENTUM AND OF THE PION EMISSION VOLUME IN PROTON NUCLEUS AND ANTI-PROTON NUCLEUS REACTIONS AT 200-GEV

De Marzo, C. ; De Palma, M. ; Distante, A. ; et al.
Phys.Rev.D 29 (1984) 363-367, 1984.
Inspire Record 202202 DOI 10.17182/hepdata.23727

We have measured 〈p⊥〉 as a function of multiplicity for the reaction proton (antiproton) on proton, neon, argon, and xenon. For all reactions, 〈p⊥〉 is independent of multiplicity. We observed that the pion-emission volume is the same for both hydrogen and xenon targets and has a radius about 1.5 fm. Our analysis shows no indication of a deconfinement phase transition in nuclear matter.
