Sumario: | Hard exclusive leptoproduction of real photons on nucleons and nuclei, Deeply Virtual Compton Scattering (DVCS), is one of the theoretically cleanest ways to access Generalized Parton Distributions (GPDs). During 1996–2006 the HERMES experiment at DESY, Hamburg, collected data on DVCS utilizing the HERA polarized electron or positron beams with energies of 27.6 GeV, and longitudinally and transversely polarized or unpolarized gas targets (H, D or heavier nuclei). The azimuthal asymmetries measured in the DVCS process allow access to the imaginary and/or real part of certain combinations of GPDs. An overview of the latest HERMES results on DVCS is presented. |
