Anomalous GPDs in the photon

We consider deeply virtual Compton scattering (DVCS) on a photon target, in the generalized Bjorken limit, at the Born order and in the leading logarithmic approximation. This leads us to the extraction of the photon anomalous generalized parton distributions (GPDs) [S. Friot, B. Pire and L. Szymanowski, Phys. Lett. B 645 153 (2007)].
