Looking for the gluonic EMC effect in associated $J/\psi$ + $\gamma $ production

High Energy Physics - Phenomenology 2011-07-19 v2

Abstract

We study the associated production of J/ψ +γ J/\psi\ + \gamma in fixed-target experiments with nuclear targets as well as at the relativistic heavy-ion collider (RHIC). We find that this process affords a very clean probe of ρg\rho_g, the ratio of gluon density in a heavy nucleus to that of a proton. The combined xx range thus available can be used to discriminate between the predictions of different models of the EMC effect for ρg\rho_g.
