Simulation of antiproton-nucleus interactions in the framework of the UrQMD model

Abstract

This paper proposes to apply the Ultra-Relativistic Quantum Molecular Dynamic (UrQMD) approach to implement the PANDA project (GSI). Modeling of $\bar{p}$A-interactions has been performed at antiproton energies from 1 GeV to 200 GeV by using the UrQMD model. We have studied average multiplicities, multiplicity distributions of various types of secondary particles, correlations between the multiplicities, rapidity, and transverse momentum distributions of the particles. The UrQMD model predictions on inelastic $\bar{p}$A- collisions have been found to reproduce qualitatively the experimental data. However, to reach the quantitative agreement, especially, in fragmentation regions, it is needed to modify the UrQMD model.
