TL;DR
This paper presents recent experimental results on deeply virtual Compton scattering from H1, ZEUS, and HERMES, including cross section measurements and asymmetry analyses, advancing understanding of the proton structure.
Contribution
It provides new measurements of the DVCS cross section and asymmetries at HERA, including the first t-dependence of beam-charge asymmetry on hydrogen and deuterium.
Findings
Increased statistics in cross section measurements at H1 and ZEUS
First measurement of t-dependence of beam-charge asymmetry on hydrogen
Beam-charge asymmetry measurement on deuterium
Abstract
The process of deeply virtual Compton scattering will be shortly introduced, and the latest results from measurements at the HERA ep-collider at DESY will be given. In particular, the cross section has been measured with increased statistics at the collider experiments H1 and ZEUS, while HERMES for the first time reports measurements of the t-dependence of the beam-charge asymmetry on hydrogen and of a beam-charge asymmetry on deuterium.
