Influence of the Nucleon Hard Partons Distribution on J/\Psi Suppression in a GMC Framework

Abstract

In a Glauber Monte Carlo framework, taking account of the transverse spatial distribution of hard partons in the nucleon, we analyse the nuclear modification factor RdAuR_{dAu} for J/ψJ/\psi in d+Au collisions with the EPS09 shadowing parametrization. After the influence of nucleon hard partons distribution is considered, a clearly upward correction is revealed for the dependence of RdAuR_{dAu} on NcollN_{coll} in peripheral d+Au collisions, however, an unconspicuous correction is shown for the results versus pTp_{T}. The theoretical results are in good agreement with the experimental data from PHENIX.
