Deeply Virtual Compton Scattering at H1 and ZEUS

TL;DR

This paper reports the first measurements of the Deeply Virtual Compton Scattering cross section at HERA by H1 and ZEUS, comparing results with theoretical predictions in the low x and high Q^2 region.

Contribution

It provides the first experimental measurements of DVCS cross sections at HERA, expanding the understanding of this process in the low x and high Q^2 regime.

Findings

Measured DVCS cross sections for the first time at HERA.

Compared experimental results with various theoretical models.

Observed agreement/discrepancies with predictions.

Abstract

Results on Deeply Virtual Compton Scattering at HERA measured by the H1 and ZEUS Collaborations are presented. The cross section, measured for the first time, is reported for by H1 and ZEUS for $Q^2$ above a few GeV$^2$ in the low $x$ region. The measured cross section is discussed and compared to different predictions.
