English abstract | In this work we calculate the J/ψ production in the initial stage of proton-proton, proton-nucleus and nucleusnucleus collisions at RHIC and LHC energies, taking into account the high parton density regime of QCD, where the physics of parton saturation is expected to be dominant. We perform a quantitative analysis of the xF distributions in these collisions with the Color Glass Condensate (CGC) approach. The ratio between distributions with or without saturated gluons shows that this mechanism produces a suppression on the J/ψ yield in the forward region and presents a dip in intermediate values of xF , which is visible only at LHC energies |
