Abstract

HIJING generator simulation of nucleus-nucleus collisions at ultrarelativistic energies are presented. Is shown, that the global characteristics of nucleus-nucleus collisions, such as of distribution of a charge multiplicity, total and electromagnetic transverse energy over pseudorapidity are rather sensitive to some predictions of formation models of high-exited nuclear medium, namely parton energy losses in dense nuclear matter. This losses results to appearance of a broad maximum in global variable distributions over pseudorapidity. The most profound of this effect occurs at central heavy ion collisions at LHC energy.
