Description
abstract: At very high collision energies QCD enters a new regime governed by large gluon densities and non-linear coherent phenomena, globally referred to as gluon saturation effects. In the introduction I shall briefly discuss the basic ingredients for the theoretical formulation of the gluon saturation regime of QCD. Then I I will focus in the phenomenological searches of these high-density effects in several experimental programs (past and future Deep Inelastic Scattering programs and p+p and heavy ion collisions at RHIC and the LHC) and their possible consequences in astroparticle observations like UHE neutrino-nucleon scattering or cosmic rays. I will argue that while no definitive conclusion can be extracted from the analyses of presently available data, it is fair to say that many observables from a variety of collision systems find their natural explanation and a good quantitative description in terms of non-linear dynamics associated to the presence of large gluon densities.
