Abstract: | We apply our microscopic model for the topological cross section σn to produce n charged particles in hadron-proton interactions to hadron-nucleus scattering. The model is based on a stochastic branching process for hadronization. We calculate multiplicity distributions of hadron-nucleus collisions for 50 GeV ? EL ? 400 GeV based on a multiple collision model. The production of “grey” particles is considered together with the shower particles in order to test the model for higher number of collisions. The joint probability distribution of numbers of shower and grey particles F(ns, ng) is calculated. Finally, we critically compare the results to experimental data. |
