Description
I explain how to resum the threshold x -> +-xB logarithms in the hard coefficient function for the virtual Compton process in momentum space. This is the off-forward generalization of the threshold resummation in DIS in the endpoint xB -> 1 region. The interesting case is that of an outgoing real photon, i.e. DVCS, where the threshold limit corresponds to the limit of zero parton momenta x -> +-xi. I discuss why the logs are generally not large and hence the resummation does is not expected to give a sizable correction to DVCS observables.
