Diffractive open charm production from the dipole model analysis

TL;DR

This paper compares dipole model predictions with recent HERA data on diffractive open charm production, confirming good agreement and showing that exclusive diffractive charm production is negligible.

Contribution

It provides a detailed comparison between dipole models and experimental data, validating the models' accuracy for diffractive open charm production.

Findings

Good agreement between dipole models and HERA data.

Exclusive diffractive charm production is negligible.

Dipole models accurately describe diffractive open charm production.

Abstract

We present a precise comparison of the results of the dipole models with the newest data from HERA on the diffractive open charm production. We found good agreement with the data on the diffractive open charm production both for the the gluon distributions from the considered dipole models and the DGLAP fits to HERA data from our earlier analysis for diffractive parton distributions with higher twist. We also show that exclusive diffractive charm production can practically be neglected
