Abstract:
The nuclear collisions at high energies offer conditions for different phase transition in nuclear matter. One of main goal of the BRAHMS Experiment is the establishing of the collisions dynamics and the search for the experimental signals in order to show quark-gluon plasma. Because the dynamics is in great extent dependent on the collision geometry we consider necessary a good correlation between the level of centrality of the collision ad behaviour of some specific physical quantities. The present work considers the analysis of the multiplicity distribution shape in relationship whit the impact parameter and also comparasion of the experimental results with the prediction of differenr simulation models.Considering the experimental results
