Single and double diffractive dissociation and the problem of extraction of the proton-Pomeron cross-section

Abstract

Diffractive dissociation processes are analysed in the framework of covariant reggeization. We have considered the general form of hadronic tensor and its asymptotic behaviour for $t\to 0$ in the case of conserved tensor currents before reggeization. Resulting expressions for differential cross-section of single dissociation (SD) process ($pp\to pM$), double dissociation (DD) ($pp\to M_1{M}_2$) and for the proton-Pomeron cross-section are given in detail, and corresponding problems of the approach are discussed.
