Hadron production in heavy ion collisions: Fragmentation and recombination from a dense parton phase


Journal Article

We discuss hadron production in heavy ion collisions at the Relativistic Heavy Ion Collider (RHIC). We argue that hadrons at transverse momenta [Formula Presented] are formed by recombination of partons from the dense parton phase created in central collisions at RHIC. We provide a theoretical description of the recombination process for [Formula Presented]. Below [Formula Presented] our results smoothly match a purely statistical description. At high transverse momentum hadron production is well described in the language of perturbative QCD by the fragmentation of partons. We give numerical results for a variety of hadron spectra, ratios, and nuclear suppression factors. We also discuss the anisotropic flow [Formula Presented] and give results based on a flow in the parton phase. Our results are consistent with the existence of a parton phase at RHIC hadronizing at a temperature of [Formula Presented] and a radial flow velocity of [Formula Presented]. © 2003 The American Physical Society.
