DVCS results from HERMES

The HERMES experiment studies the spin structure of the nucleon using the 27.6 GeV longitudinally polarized positron beam of HERA and internal targets of pure gases. Recently, HERMES has published measurements of azimuthal single‐spin asymmetries in the hard electroproduction of photons on an unpolarized hydrogen target arising from the interference of the amplitudes of the Bethe‐Heitler (BH) and the Deeply Virtual Compton Scattering (DVCS) processes. The measurements constitute an effort towards accessing generalized parton distributions, and open a new approach to study the spin structure of the nucleon.
