Energy and Atomic Mass Dependence of Nuclear Stopping Power in Relativistic Heavy-Ion Collisions in Interacting Gluon Model

Abstract

We present a Monte-Carlo simulation of energy deposition process in relativistic heavy-ion collisions based on a new realization of the Interacting-Gluon-Model (IGM) for high energy $N-N$ collisions. In particular we show results for proton spectra from collisions of $E_{lab}=200GeV/N$ ${}^{32}$S beam incident on ${}^{32}$S target and analyze the energy and mass dependence of nuclear stopping power predicted by our model. Theoretical predictions for proton rapidity distributions of both ${}^{208}$Pb + ${}^{208}$Pb collisions at $E_{lab}=160GeV/N$ CERN SPS and ${}^{197}$Au + ${}^{197}$Au at $\sqrt{s_{NN}}=200GeV$ BNL RHIC are given.
