Color strings, pomeron shadowing and Color Glass Condensate

Abstract

I 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 shadowing in a Pomeron approach.Comment: 8 pages, 3 figures, Fifth International Conference on Perspectives in Hadronic Physics 22-26 May 2006 Trieste, Ital
