HighpTAzimuthal Asymmetry in NoncentralA+Aat RHIC

Abstract
The high pT>3GeV azimuthal asymmetry, v2(pT), in noncentral nuclear collisions at RHIC is shown to be a sensitive measure of the initial parton density distribution of the produced quark-gluon plasma. A generalization of the Gyulassy-Lévai-Vitev non-Abelian energy loss formalism including Bjorken (1+1)D expansion as well as important kinematic constraints is used.
