Abstract
We compute the virtual next-to-leading corrections to the impact facto rs or off-shell coefficient functions in the high-energy limit, in the helicity-amplitude formalism. These agree with previous results by Fa din and collaborators, in the conventional dimensional-regularization scheme. When combined with the known real corrections, these results w ill 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.
