Forward-backward multiplicity correlation in high energy hadron-hadron collisions

Abstract

The forward-backward multiplicity correlation over the full pseudorapidity range for pp and p {Mathematical expression} collisions at ISR and Collider energies have been analysed in terms of 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. Reasonable agreement with experimental data is obtained if the final-state particles are assumed, in a cluster model, to be created by the decay of clusters with a mean cluster size (charged particles per cluster) which is energy-dependent. © 1989 Springer-Verlag.
