Virtual next-to-leading corrections to the impact factors in the high-energy limit

We compute the virtual next-to-leading corrections to the impact factors or off-shell coefficient functions in the high-energy limit, in the helicity-amplitude formalism. These agree with previous results by Fadin and collaborators, in the conventional dimensional-regularization scheme. When combined with the known real corrections, these results will provide the complete NLO corrections to the impact factors, which are necessary to use the BFKL resummation at NLL for jet production at both lepton-hadron and hadron-hadron colliders.
