Abstract：
The multiplicity distributions and correlations of grey track producing particles(N _g), black track producing particles(N _b) and heavy track producing particles(N _h) 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 into account and DTUNUC 2.0 with an incident energy of 200 A GeV. The mean multiplicity of black particles b> increases with the number of grey particle N _gup to 10 and then exhibits a saturation for peripheral,central and mini-bias events;the average values of grey particles g>(heavy track producing particles h>)inerease with increasing values of black particle N _b(grey particle N _g).
