Dipole model analysis of the newest diffractive deep inelastic scattering data

TL;DR

This paper uses dipole models to analyze recent diffractive deep inelastic scattering data from HERA, highlighting the importance of open charm contributions and suggesting improvements for large diffractive mass regions.

Contribution

It provides a detailed dipole model analysis of the latest HERA data, emphasizing the role of open charm and proposing refinements for high diffractive mass regions.

Findings

Good agreement with data when open charm is included

Large diffractive mass region requires additional gluon radiation modeling

Dipole models effectively describe diffractive structure functions

Abstract

We analyse the newest diffractive deep inelastic scattering data from the DESY collider HERA with the help of dipole models. We find good agreement with the data on the diffractive structure functions provided the diffractive open charm contribution is taken into account. However, the region of large diffractive mass (small values of a parameter beta) needs some refinement with the help of an additional gluon radiation.
