J/ψ PRODUCTION IN A GLAUBER MONTE CARLO FRAMEWORK.

By means of a Glauber Monte Carlo framework, the J/ψ production at RHIC energies is studied with the EKS98, EPS09 and HKN07 shadowing parameters. With a χ2 analysis of the experimental data given by PHENIX, a significant dependence of the absorption cross-section, σabs, on the J/ψ-nucleon center-of-mass energy, $\sqrt{s_{J/\psi-N}}$, is revealed with the HKN07 shadowing, but an unconspicuous dependence is shown with the EKS98 and EPS09 shadowing. In this paper, the nuclear modification factor Rd Au vs y, pT and Ncoll are also calculated and the theoretical results are in good agreement with the experimental data. [ABSTRACT FROM AUTHOR]
