Abstract
Differential elliptic flow out to p_T ~ 5 GeV/c and particle spectra are calculated using the MPC elastic parton cascade model for Au+Au at Ecm ~ 130A GeV. The evolution is computed from parton transport theory, followed by hadronization either via independent fragmentation or by imposing parton-hadron duality. With pQCD elastic cross sections, very large initial gluon densities dN/deta > 7000 are required to reproduce the data measured by the STAR collaboration. In addition, elliptic flow and the p_T spectra are shown to be very sensit ive to particle subdivision.
