Triple Pomeron and Proton Diffraction Dissociation

TL;DR

This paper models proton diffraction dissociation using a dipole Pomeron with a double pole, successfully fitting experimental cross sections without requiring the triple Pomeron vertex to decouple, thus maintaining unitarity.

Contribution

It introduces a dipole Pomeron model with a double pole in the J-plane that satisfies unitarity without decoupling the triple Pomeron vertex, providing a new approach to diffraction analysis.

Findings

Differential and total diffractive cross sections are accurately reproduced.

Unitarity is maintained without decoupling the triple Pomeron vertex.

The model aligns well with experimental data.

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.
