Descripción: We present a new approach to estimate the effect of gluon shadowing in nucleus + nucleus collisions and its consequences on the J / ψ production yield. Using kinematical information available from the measured J / ψ production in proton + proton collisions at GeV, we build a Glauber Monte Carlo code which takes into account shadowing in two alternative ways: multiple-scattering corrections or Q 2 evolution of parton densities. We exploit the dependence of these different parameterizations to the J / ψ transverse momentum and we give the first predictions on the resulting p T dependence of the nuclear modification factor in deuteron + gold collisions at the same energy.
