Deeply Virtual Compton Scattering at HERA
Abstract
Description
The Deeply Virtual Compton Scattering (DVCS) $γ^* p \to γp$ cross section has been measured with the H1 detector at HERA with an increased precision and in an extended kinematic domain: at photon virtualities $4<Q^2<80$ GeV$^2$, and photon-proton c.m.s. energy $30<W<140$ GeV. The measurement is compared to NLO QCD calculations and to Colour Dipole model predictions.
