Charged particle multiplicity in π−–nucleus interactions at 50 GeV/c in nuclear emulsion

Abstract

Experimental results on charged particle multiplicity of the interactions of 50 GeV/c negative pions with emulsion nuclei are presented. The values of [Formula: see text], [Formula: see text], and D are found to be 8.35 ± 0.17, 7.11 ± 0.25, and 4.75 ± 0.08 respectively. The results of π−–emulsion interactions are compared with those of p–emulsion interactions. The dependence of the parameter RA on mass number A has been examined and compared with the existing models of hadron–nucleus interactions.
