TL;DR

This paper develops DGLAP evolution equations for gluon production in diffractive deep inelastic scattering, successfully describing experimental data with a small coupling and highlighting the need for next-to-leading order corrections.

Contribution

It introduces a DGLAP evolution framework derived from the Color Glass Condensate approach for diffractive gluon production in DIS, a novel application in this context.

Findings

Successfully describes experimental data with small coupling

Identifies the gluonic system as dilute in diffractive production

Highlights the necessity for next-to-leading order development

Abstract

In this paper we develop the DGLAP evolution for the system of produced gluons in the process of diffractive production in DIS, directly from the evolution equation in Color Glass Condensate approach. We are able to describe the available experimental data with small value of the QCD coupling ($\bar{\alpha_S} \approx 0.1$). We conclude that in diffractive production, we have a dilute system of emitted gluons and in the order to describe them, we need to develop the next-to-leading order approach in perturbative QCD.
