Deeply Virtual Compton Scattering at HERA
  The Deeply Virtual Compton Scattering (DVCS) $\gamma^* p \to \gamma p$ cross section has been measured with the H1 detector at HERA with an increased precision and in an extended kinematic domain: at photon virtualities $4<Q^2<80$ 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.
