Vector meson production at HERA

TL;DR

This paper reviews the experimental findings of exclusive vector meson production at HERA, focusing on the transition from soft to hard diffraction and its interpretation within Quantum Chromodynamics (QCD).

Contribution

It provides a comprehensive overview of experimental results and discusses the transition from soft to hard diffraction in vector meson production at HERA.

Findings

Evidence of transition from soft to hard diffraction

QCD-based interpretations of vector meson production

Experimental data supporting theoretical models

Abstract

The rich experimental landscape of exclusive vector meson production at the high energy electron-proton collider HERA is reviewed, with emphasis on the transition from soft to hard diffraction and QCD interpretations.
