Deeply Virtual Compton Scattering at HERA
Abstract
The Deeply Virtual Compton Scattering (DVCS) γ* p γ p 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<Q2<80 GeV2, 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.
