Abstract

The analysis of two-particle azimuthal correlation function in p+p and Au+Au collisions at s(NN)**(1/2) 200 GeV/c is presented. The mean jet fragmentation transverse momentum <|mjTy|> and mean parton transverse momentum <|kTy|> are inferred from p+p collisions. The analysis of Au+Au data, where elliptic flow is a dominant source of two-particles correlation is also presented. We derive the upper limit on partonic azimuthal anisotropy based on jet-quenching in a Glauber model. We show that some new mechanism, generating the azimuthal anisotropy observed in final state, is needed.
