`Effective' Pomeron model at large $\mathbf{b}$

Abstract

In this paper we consider the influence of non-perturbative corrections on the large $b$ (impact parameter) behavior of the BFKL amplitude. This is done in the framework of a model where such ``soft'' corrections are taken into account in the BFKL kernel. We show, that these corrections lead to a power-like decreasing behavior of amplitude, which differs from the BFKL case.
