Semi-hard scattering of partons at SPS and RHIC: A study in contrast
arXiv:nucl-th/0210042 · doi:10.1103/PhysRevC.66.061902
Abstract
We analyze the contribution of pQCD based semi-hard parton (re)scattering to the reaction dynamics of relativistic heavy-ion collisions at SPS and RHIC. While such processes are able to account for the measured yield of high momentum direct photons at SPS energies, the conditions necessary for jet-quenching are not fulfilled. The situation changes dramatically at RHIC energies.
