Inclusive diffraction at HERA

TL;DR

This paper presents a new experimental analysis of diffractive electron-proton scattering at HERA, comparing results with other measurements and theoretical models to enhance understanding of diffraction phenomena.

Contribution

It provides the first detailed analysis of the diffractive process $ep ightarrow eXY$ with low mass proton excitations at HERA, including comparisons to existing data and theories.

Findings

Consistent measurements of diffractive cross sections

Comparison with theoretical predictions shows good agreement

Enhanced understanding of low-mass proton excitations

Abstract

A new experimental analysis of the diffractive process $ep \rightarrow eXY$, where $Y$ denotes a proton or its low mass excitation with $M_Y<1.6$ GeV, has been performed with the H1 experiment at HERA \cite{Aaron:2012ad}. The main results of this study are summarised in this document, together with the comparisons to other measurements and theoretical predictions.
