Query: One-Loop Corrections and All Order Factorization In Deeply Virtual
  Compton Scattering   We calculate the one-loop corrections to a general off-forward deeply-virtual
Compton process at leading twist for both parton helicity-dependent and
independent cases. We show that the infrared divergences can be factorized
entirely into off-forward parton distributions, even when one of the two
photons is onshell. We argue that this property persists to all orders in
perturbation theory. We obtain the next-to-leading order Wilson coefficients
for the general leading-twist expansion of the product of two electromagnetic
currents in the \overline{\rm MS} scheme.
