Multiplicity and mean transverse momentum fluctuations in Au + Au collisions at RHIC
Strong modification of event-by-event fluctuations in global observables was proposed by several authors as an indicator of the phase transition in system evolution. We report the results of the analysis of STAR TPC data on the charged multiplicity and mean transverse momentum fluctuations in Au+Au collisions at $\sqrt{s_{NN}}$=130 GeV. We discuss the centrality dependence of the observed fluctuations and compare the results with available data from lower collision energies and ISR data.
