Backward DVCS and Proton to Photon Transition Distribution Amplitudes
arXiv:hep-ph/0607130 · doi:10.1016/j.nuclphysa.2006.10.014
Abstract
We analyse deeply-virtual Compton scattering on a proton target, gamma* P -> P' gamma in the backward region and in the scaling regime. We define the transition distribution amplitudes which describe the proton to photon transition. Model-independent predictions are given to test this description, for current or planned experiments at JLab or by Hermes.
