Exclusive Vector Meson Production and Deeply Virtual Compton Scattering at HERA

TL;DR

This paper reviews HERA's experimental results on exclusive vector meson production and deeply virtual Compton scattering, highlighting their significance for understanding proton structure and the transition from soft to hard QCD processes.

Contribution

It summarizes HERA's key experimental data on these reactions and discusses their interpretation within Quantum Chromodynamics (QCD) frameworks.

Findings

Experimental data supports QCD-based models of proton structure

Evidence of transition from soft to hard scattering regimes

Insights into the gluonic content of the proton

Abstract

Exclusive vector meson production and deeply virtual Compton scattering are ideally suited reactions for studying the structure of the proton and the transition from soft to hard processes. The main experimental data obtained at HERA are summarised and presented in the light of QCD approaches.
