The dynamics of high partonic density QCD is presented considering, in the double logarithm approximation, the parton recombination mechanism built in the AGL formalism, developed including unitarity corrections for the nucleon as well for nucleus. It is shown that these corrections are under theoretical control. The resulting non linear evolution equation is solved in the asymptotic regime, and a comprehensive phenomenology concerning Deep Inelastic Scattering like F2, F L, F<img SRC="http:/img/fbpe/bjp/v31n2/02eq43.gif">. <FONT FACE=Symbol>¶</FONT>F2 / <FONT FACE=Symbol>¶</FONT>ln Q², <FONT FACE=Symbol>¶</FONT>F<img SRC="http:/img/fbpe/bjp/v31n2/02eq44.gif"> / <FONT FACE=Symbol>¶</FONT>ln Q², etc, is presented. The connection of our formalism with the DGLAP and BFKL dynamics, and with other perurbative (K) and non perturbative (MV-JKLW) approaches is analised in detail. The phenomena of saturation due to shadowing corrections and the relevance of this effect in ion physics and heavy quark production is emphasized. The implications to e-RHIC, HERA-A, and LHC physics and some open questions are mentioned. |
