pi/K/p production and Cronin effect from p+p,d+Au and Au+Au collisions at root(NN)-N-S=200 GeV from the PHENIX experiment

摘要

We present results on identified particle production in p+p, d+Au and Au+Au collisions at rootS(NN) = 200 GeV at mid-rapidity measured by the PHENIX experiment. The centrality and flavour dependence of the Cronin effect in d+Au collisions is measured. The Cronin effect for the protons in d+Au is larger than that for the pions, but not large enough to account for the 'anomalous' proton-to-pion ratio in central Au+Au collisions.
