Abstract
HERMES has measured azimuthal beam-spin and beam-charge asymmetries in hard electroproduction of photons on nucleons and nuclei. Attributed to the interference of the Bethe-Heitler process and the Deeply Virtual Compton scattering process (DVCS), these asymmetries give access to the latter at the amplitude level. This process provides the theoretically cleanest way to access generalized parton distributions and thus new information on the structure of nucleons and nuclei. The data were accumulated by the HERMES experiment at DESY scattering the HERA 27.6 GeV electron or positron beam off hydrogen, deuterium and neon gas targets.
