Extraction of the Generalized Parton Distribution H(xi,xi,t) from DVCS

Abstract

A simple way to extract the Generalized Parton Distribution H(xi,xi,t) at small t from the single beam-spin asymmetry in Deeply Virtual Compton Scattering is proposed. Projections are given for future measurements at the HERMES experiment upgraded with a recoil detector.
