"Hard" Pomeron approach to "soft" processes at high energy

An attempt is made to give a consistent description of high energy hadron interactions starting with the physical assumption that only "hard" processes contribute to the Pomeron structure. Using the general properties of a "hard" Pomeron in perturbative QCD an equation for shadowing corrections is suggested and solved. It allows one to extend the new approach to high energy hadron collisons. In doing so we generalize the so-called eikonal approximation widely used to describe the shadowing corrections for both hadron and nucleus scattering at high energy. New formulas are also suggested for the large rapidity gap survival probability which crucially differ from the eikonal ones.
