Abstract

Multiparticle production in limited pseudo-rapidity intervals for nucleus-nucleus collisions have been studied in a geometric model. It has been shown that in the energy range 60– 200 GeV/nucleon the data can be well described by the model. It has also been shown that three-and four-particle correlations are negligible in this energy range. Two-particle correlation strengths have been estimated to be of the order of 0.2. We have shown that if the nucleon-nucleon multiplicity distributions obey the negative binomial law, then in the geometric model, a linear relation exists between the second moment of the nucleus-nucleus distributions and the parameter 1 k of the negative binomial distributions. The experimental data indeed show such a relationship.
