Dipole model analysis of highest precision HERA data, including very low $Q^2$'s

TL;DR

This paper demonstrates that the dipole model accurately describes the highest precision HERA deep inelastic scattering data across a wide range of momentum transfer values, including very low $Q^2$ regions.

Contribution

It provides a comprehensive analysis of HERA data within the dipole model, extending the model's applicability down to very low $Q^2$ values and confirming its effectiveness.

Findings

Dipole model fits data well from $Q^2$ of 3.5 GeV$^2$ to 250 GeV$^2$.

High-precision HERA data are well described by the dipole model.

The analysis includes fully correlated errors for robust results.

Abstract

We analyse, within a dipole model, the final, inclusive HERA DIS cross section data in the low $x$ region, using fully correlated errors. We show, that these highest precision data are very well described within the dipole model framework starting from $Q^2$ values of 3.5 GeV$^2$ to the highest values of $Q^2 =$ 250 GeV$^2$.
