Saturation and non-linear effects in diffractive processes

Abstract

Through a direct implementation of the saturation regime resulting from the unitarity limit in the impact parameter representation, we explore various possibilities for the energy dependence of hadronic scattering. We show that it is possible to obtain a good description of the scattering amplitude from a hard pomeron provided one includes non-linear effects.Comment: Contribution to the XIth International Conference on Symmetry Methods in Physics (SYMPHYS-11), Prague, 21st to 24th June, 2004. 9 pages, 3 figures, uses icsm.cls (provided).
