Precise dipole model analysis of diffractive DIS

TL;DR

This paper analyzes recent diffractive deep inelastic scattering data from HERA using the dipole model, achieving good agreement but noting the need for refinement at small $eta$ values, possibly via diffractive parton distributions with DGLAP evolution.

Contribution

It applies the dipole model to the latest HERA data and suggests incorporating diffractive parton distributions with DGLAP evolution for improved accuracy.

Findings

Good agreement with data overall

Region of small $eta$ requires refinement

Potential improvement with DGLAP-evolved diffractive parton distributions

Abstract

We analyse the newest diffractive deep inelastic scattering data from HERA using the dipole model approach. We find a reasonable good agreement between the predictions and the data although the region of small values of a kinematic variable $\beta$ needs refinement. A way to do this is to consider an approach with diffractive parton distributions evolved with the DGLAP evolution equations.
