Diffractive processes at high energies

Abstract

In this work we calculate pomeron flux in the single diffraction processes. We consider two models: quasi-eikonal model and low constituent model. Both models give the pictures different from the traditional three-reggeon model. Successive developing of modeles gives some indications, that the low constituent model is more attractive.
