Incident-energy and system-size dependence of directed flow

Nuclear Experiment 2008-11-26 v2

Abstract

We present STAR's measurements of directed flow for charged hadrons in Au+Au and Cu+Cu collisions at sNN=200\sqrt{s_\mathrm{NN}} = 200 GeV and 62.4 GeV, as a function of pseudorapidity, transverse momentum and centrality. We find that directed flow depends on the incident energy, but not on the system size. We extend the validity of limiting fragmentation hypothesis to different collision systems.
