Multiparticle production through isoscalar clusters

The isoscalar cluster model for multiparticle production was extended to include clusters of A2 meson pairs in addition to previously studied rho-rho and sigma clusters. The production of each type of cluster is given by an energy dependent Poisson distribution. The Poisson parameters determined from the charged particle multiplicity distributions indicate that the inclusion of A2-A2 clusters does not improve the fit to the data. The predictions of the model for n0 n/sub -/, f/sup 2//sub -,-/, and f/sup 2//sub 0,0/ compare favorably to the experimental values. (U.S.)
