HARD POMERON APPROACH TO SOFT PROCESSES AT HIGH-ENERGY

An attempt is made to give a consistent description of high energy had ron interactions starting with the physical assumption that only ''har d'' processes contribute to the Pomeron structure. Using the general p roperties of a ''hard'' Pomeron in perturbative QCD an equation for sh adowing corrections is suggested and solved. It allows one to extend t he new approach to high energy hadron collisons. In doing so we genera lize the so-called eikonal approximation widely used to describe the s hadowing corrections for both hadron and nucleus scattering at high en ergy. New formulas are also suggested for the large rapidity gap survi val probability which crucially differ from the eikonal ones.
