摘要
Particle-type dependences of hadron yield suppression/enhancement patterns, especially its difference between mesons and baryons, at intermediate p(T) (2-5 GeV/c) is one of the findings in heavy ion collisions at RHIC. Asystematic study of identified hadron production was performed in Au+Au/Cu+Cu collisions at root(NN)-N-S = 62.4/ 200 GeV, to investigate the possible origins of this difference. In this paper, we show particle ratios, nuclear modification factors and their scaling properties.
