- J/ production in the Saturation Regime F. O. Durães Física, Astronomía y Matemáticas ψ Nucleus production nucleus collisions Color Glass Condensate In this work we calculate the J/ψ production in the initial stage of proton-proton, proton-nucleus and nucleusnucleuscollisions at RHIC and LHC energies, taking into account the high parton density regime of QCD, wherethe physics of parton saturation is expected to be dominant. We perform a quantitative analysis of the xF distributionsin these collisions with the Color Glass Condensate (CGC) approach. The ratio between distributionswith or without saturated gluons shows that this mechanism produces a suppression on the J/ψ yield in theforward region and presents a dip in intermediate values of xF , which is visible only at LHC energies. 2007 artículo científico 0103-9733 https://www.redalyc.org/articulo.oa?id=46437133 en http://www.redalyc.org/revista.oa?id=464 Brazilian Journal of Physics application/pdf Sociedade Brasileira de Física Brazilian Journal of Physics (Brasil) Num.1A Vol.37
