Nuclear modification factors at forward rapidity in Au–Au and Cu–Cu collisions at = 62.4 GeV

Abstract

Data from Au–Au, Cu–Cu and p–p collisions at GeV have been collected by the BRAHMS experiment from pseudorapidity η = 0–3.1. Nuclear modification factors, RAA at forward rapidity, with pT up to ∼2 GeV/c, which corresponds to more than half of the kinematical limit, are presented together with results from midrapidity for Au–Au and Cu–Cu collisions. They will also be shown as a function of centrality.
