Recent HERMES Results on DVCS

Abstract

The interference of Deeply Virtual Compton Scattering (DVCS) and Bremsstrahlung leads to a beam-charge asymmetry that can be observed for exclusive photon production in the collision of high energy leptons and nucleons/nuclei. Recent results for a hydrogen and a deuterium target are reported and a consistent tendency for a rise of the cosine phi coefficient with momentum transfer |t| has been found.
