High transverse momentum suppression and surface effects in Cu+Cu and Au+Au collisions within the PQM model

摘要

We study parton suppression effects in heavy-ion collisions within the parton quenching model (PQM). After a brief summary of the main features of the model, we present comparisons of calculations for the nuclear modification and the away-side suppression factor to the data in Au + Au and Cu + Cu collisions at root s(NN) = 200 GeV. We discuss properties of light hadron probes and their sensitivity to the medium density within the PQM Monte Carlo framework.
