Description
Heavy ion reactions at ultrarelativistic energies provide information on strongly interacting matter under extreme conditions. In these collisions a large number of particles of different types is produced. Current understanding of such collisions suggest that the production of a QGP phase in relativistic heavy ion collisions could produce significant event-by-event correlations and fluctuations in transverse momentum, multiplicity, etc. Therefore it is important to analyze fluctuations of multiplicities (net-protons, net-strangeness, total protons) for different energies and centralities and search for anomalous behaviour due to a phase transition. The multiplicity distributions of different types of particles produced in simulated Au+Au collisions using different theoretical models at energies ranging from 2 – 200 AGeV were analyzed and the moments of the distributions were calculated. Model results can be used to provide a baseline for the phase transition and QCD critical point search. The centrality and beam energy dependence of the moments of simulated multiplicity distributions will be shown and discussed.
