Measurement of deeply virtual Compton scattering at HERA

A measurement is presented of elastic deeply virtual compton scattering e"++p#->#e"++#gamma#+p at HERA using data taken with the H1 detector. The cross section is measured as a function of the photon virtuality, Q"2, and the invariant mass, W, of the #gamma#p system, in the kinematic range 2< Q"2 <20 GeV"2, 30<W<120 GeV and vertical stroke t vertical stroke <1 GeV"2, where t is the squared momentum transfer to the proton. The measurement is compared to QCD based calculations.
