Pt Distributions of Identified Charged Hadrons Measured with the PHENIX Experiment at RHIC

Abstract

Transverse momentum spectra of identified ${\pi }^{+}$, ${\pi }^{-}$, $K^{+}$, $K^{-}$, p and $\overline{p}$ were measured by the PHENIX experiment at mid-rapidity in Au-Au collisions at $\sqrt{s_{NN}}=130$ GeV over a broad momentum range. Inverse slope parameters and mean $p_t$ were measured in minimum bias events and as a function of the number of participating nucleons. The mass and centrality dependence of the inverse slope parameters and mean $p_t$ is presented and discussed.
