Abstract
We present azimuthal anisotropy measurements in Au+Au and Cu+Cu collisions at and 200 GeV. Comparison between reaction plane and cumulant v2 measurements in Au+Au collisions at GeV shows that non-flow contributions, originating mainly from jets, influence the extracted v2 for pT 3.5 GeV/c. Number of constituent quark (NCQ) scaling of v2, when studied as a function of transverse kinetic energy KET, is seen to hold for Au+Au collisions at and 200 GeV and for Cu+Cu collisions at GeV for KET 1 GeV. Differential hexadecupole flow v4 seems to exhibit scaling with integral v2 for centrality ≤40% as has been observed for differential v2.
