The forward-backward multiplicity correlations, the single hemisphere multiplicity distributions and the mean cluster size in high energy e+e- and hadron-hadron collisions

Abstract

A Chou-Yang Type multiplicity distribution, which consists of a stochastic (binomial) component for z=nf-nb and a nonstochastic (negative binomial) component for n=nf+nb, is used to analyse the forwardbackward multiplicity correlations and the single hemisphere multiplicity distributions for both e+e- and hadron-hadron collisions over a wide range of cms energy. Experimental data in full phase space are reasonably reproduced provided that the mean cluster size r is targetprojectile and energy dependent. © 1992 Springer-Verlag.
