Higher moments of the net-charge multiplicity distributions at RHIC energies in STAR

Abstract

We report the higher order moments of the net-charge multiplicity distributions for the Au+Au collisions at \sNN = 7.7, 11.5, 19.6, 27, 39, 62.4 and 200 GeV in the STAR experiment at the Relativistic Heavy-Ion Collider (RHIC). The energy and centrality dependence of higher moments and their products (such as $\sigma^2/M$, $S\sigma$ and $\kappa\sigma^{2}$) are presented. The data are also compared to Poisson expectations and Hadron Resonance Gas model calculations.
