Hard diffraction and the Color Glass Condensate

TL;DR

This paper explores how the Good-and-Walker picture combined with the Color Glass Condensate framework can describe hard diffraction phenomena at high energies, emphasizing the impact of Pomeron loops on evolution equations.

Contribution

It introduces a novel approach linking the Good-and-Walker picture with the CGC to analyze diffractive cross-sections, including effects of Pomeron loops.

Findings

Enhanced understanding of high-energy diffraction processes

Abstract

Following the Good-and-Walker picture, hard diffraction in the high-energy/small-x limit of QCD can be described in terms of eigenstates of the scattering matrix off a Color Glass Condensate. From the CGC non-linear evolution equations, it is then possible to derive the behavior of diffractive cross-sections at small $x.$ I discuss recent results, in particular the consequences of the inclusion of Pomeron loops in the evolution.
