Cluster Size in 400 GeV Proton-Nucleon Interactions

Abstract

An experimental study has been undertaken to determine the cluster size in p-N interactions at 400 GeV. The maximum number of charged particles constituting a cluster has been observed to be four. Comparison of this finding with those obtained for 50 GeV π⁻-nucleus, 400 GeV p-nucleus and 1000 GeV p-N reactions earlier, leads to the conclusion that the cluster size is independent of the identity and energy of the incident hadron which indicates that the dynamics of the cluster formation and hence the mechanism of hadronization in the final stage is probably the same in both types of reactions at high energies.
