Abstract

The study of high-energy proton-nucleus collisions is done with a holographic film from the exposure of CERN heavy liquid bubble chamber (HOBC) to a 360 Ge V/c proton beam. The multiplicity, the pseudorapidity distributions of its secondary charged particles and their correlations are analysed and compared with those of some Monte Carlo event generators. Results suggest that the multichain model including the concept of formation zone is suitable to reproduce our experimental data. It is found that the intranuclear cascade process is important in order to describe the production mechanism, especially in the backward hemisphere, of high-energy proton-nucleus collisions.
