2026-07-072026-07-07http://salesiana.dossiersoluciones.com/handle/123456789/103945I review the problem of parton saturation and its implications through three in principal different approaches, but somewhat related: saturation in a geometrical approach, QCD saturation through the Color Glass Condensate and perturbative Pomeron approach with initial conditions. I also make some comments about how that could be related to a Quark Gluon Plasma formation.21 pages, 5 figures, 1 tex file and 4 epsNuclear Theorytext
