Abstract

In this paper we suggest a new approach to the structure of the soft Pomeron: based on the t-channel unitarity, we expressed the exchange of the soft Pomeron through the interaction of the dipole of small size of the order of 1/Qs(Y) [Qs(Y) is the saturation momentum] with the hadrons. Therefore, it is shown that the typical distances in soft processes are small r∼1/Qs(12Y), where Y=lns. The saturation momentum, which determines the energy dependence of the scattering amplitude, is proportional to Qs2(12Y) exp(12λY), with λ≈0.2, and this behavior is in perfect agreement with the phenomenological Donnachie-Landshoff Pomeron. We demonstrate that the saturation models could describe the experimental data for σtot,σel,σdiff and Bel. Hence, our approach is a good first approximation to start discussion of the soft processes in the color glass condensate approach on the solid theoretical basis.
