Abstract
Azimuthal anisotropy (v(2)) and two-particle angular correlations of high p(T) charged hadrons have been measured in Au+Au collisions at roots(NN) = 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 p(T) partons. The monotonic rise of v(2)(p(T)) for p(T) < 2 GeV/c is consistent with collective hydrodynamical flow calculations. At p(T) > 3 GeV/c, a saturation of v(2) is observed which persists up to p(T) = 6 GeV/c.
