Rapidity gap distribution and correlation function based on a B-cluster model

A B-cluster model, which is a simple model for the independent emissions of charged and neutral clusters with M, the number of charged particles per cluster, varying from 2 to 3 is investigated. Within the model, one determines the Gaussian width sigma/sub d/ of the decay pion rapidity distribution from analysis of rapidity gap distribution and the charged-particle correlation function data. It is found that for M approximately 3 and sigma/sub d/ approximately 1, the model is compatible with these data and also with the charge transfer data considered in an earlier work. (U.S.)
