Proof of Factorization for Deeply Virtual Compton Scattering in QCD
arXiv:hep-ph/9801262 · doi:10.1103/PhysRevD.59.074009
Abstract
We show that factorization holds for the deeply virtual Compton scattering amplitude in QCD, up to power suppressed terms, to all orders in perturbation theory. Furthermore, we show that the virtuality of the produced photon does not influence the general theorem.
