Azimuthal anisotropy and correlations in the hard scattering regime at RHIC

Abstract

Azimuthal anisotropy (v2) and two-particle angular correlations of high pT charged hadrons have been measured in Au+Au collisions at sqrt[sNN]=130 GeV for transverse momenta up to 6 GeV/c, where hard processes are expected to contribute significantly. The two-particle angular correlations exhibit elliptic flow and a structure suggestive of fragmentation of high pT partons. The monotonic rise of v2(pT) for pT3 GeV/c, a saturation of v2 is observed which persists up to pT=6 GeV/c
