Semiclassical Calculation of Diffractive Parton Densities

Abstract

In this talk the relation between the semiclassical approach and the concept of diffractive parton densities is discussed. The proton rest frame calculation is organized in a way that exhibits the hard partonic cross section and the diffractive parton density as the two fundamental ingredients. The latter one is a non-perturbative quantity which, in the present model, is explicitly given by integrals of non-Abelian eikonal factors in the colour background field.
