Triple Pomeron and Proton Diffraction Dissociation

Abstract

We consider proton diffraction dissociation in the dipole Pomeron model, where the Pomeron is represented by a double pole in the $J-$plane, and show that unitarity can be satisfied without decoupling of the triple Pomeron vertex. Differential and total diffractive cross sections for the reaction $\bar{p}+p\to \bar{p}+X$ are analyzed and reproduced in this model.
