Influence of kinematical constraints on multiplicity distributions and neutral charged correlations in the independent cluster emission model

Energy-momentum conservation in the cluster production process is introduced in the independent cluster emission model using the generating functional formalism. In a simple version of the model clusters are produced which decay into a fixed number of pions. The ?? model and a model with isospin conservation in the cluster decay are used to calculate the charge distribution among the secondaries of cluster decay. Multiplicity characteristics like average multiplicity, second moments and associated average neutral multiplicities and second moments are calculated. The results are compared with experimental data.
