摘要
Deeply virtual Compton scattering has recently been studied by three HERA experiments, H1, ZEUS and HERMES, covering a broad range of kinematic regimes. We present cross section measurements of the two collider experiments in the kinematic region 2<Q^2<100 GeV^2 and 30<W<140 GeV, and compare them to QCD-based calculations. HERMES measurements of azimuthal asymmetries and their kinematical dependences are presented for Q^2>1 GeV^2 and 2<W<7 GeV.
