Abstract

We show that the numerical solution of the classical SU(3) Yang-Mills equations of motion in the McLerran-Venugopalan model for gluon production in central heavy ion collisions leads to a suppresion at low p_t and an enhancement at the intermediate p_t region as compared to peripheral heavy ion and pp collisions at the same energy. Our results are compared to previous, Color Glass Condensate inspired calculations of gluon production in heavy ion collisions. We revisit the predictions of the Color Glass Condensate model for pA (dA) collisions in Leading Order and show that quantum evolution--in particular the phenomenon of geometric scaling and change of anomalous dimensions--preserves the Cronin enhancement of pA cross section (when normalized to the leading twist term) in the Leading Order approximation even though the p_t spectrum can change. We comment on the case when gluon radiation is included.
