Centrality and rapidity dependence of particle ratios in Au+Au and Cu+Cu collisions at $\sqrt{s_{NN}}$ = 62.4 GeV

Abstract

We report on preliminary identified particle ratios from Au+Au collisions at $\sqrt{s_{NN}}=62.4$ GeV in different centrality classes, measured with the BRAHMS spectrometer. Results from Cu+Cu and p+p collisions at mid-rapidity at the same energy are also included. The average transverse momenta of particle spectra, anti-particle to particle ratios and $K/\pi$ ratios dependence on centrality and rapidity are shown and discussed.
