Abstract
We show that the one-loop QCD correction to deeply virtual Compton scattering can be factorized into finite perturbative contributions and collinearly divergent terms, which correspond to the matrix elements of the off-forward parton distributions. As a by-product, we obtain the next-to-leading order coefficient functions in the generalized operator product expansion of two vector currents.Keywords
