Investigation of the production of slow particles in 60 A GeV 16O induced nuclear emulsion reaction

The multiplicity distributions and correlations of grey track producing particles (Ng), black track producing particles (Nb) and heavy track producing particles (Nh) have been studied in 60 A GeV 16O induced nuclear emulsion reaction. The multiplicity distributions of grey particles, black particles and heavy track producing particles can be reproduced by FRITIOF (version 1.7) taking cascade mechanism in to account and DTUNUC2.0 with an incident energy of 200 A GeV. The mean multiplicity of black particles (Nb) increases with the number of grey particle Ng up to 10 and then exhibits a saturation for peripheral, central and mini-bias events; the average values of grey particles (heavy track producing particles increase with increasing values of black particle Nb (grey particle Ng)
