Quark impact factors - art. no. 094006

We calculate in the next-to-leading approximation the nonforward quark impa ct factors for both singlet and octet color representations in the t channe l. The integral representation of the octet impact factor in the general ca se of arbitrary space-time dimension and massive quark flavors is used to c heck the so-called "second bootstrap condition" for gluon Reggeization at t he next-to-leading logarithmic approximation in perturbative QCD. We find t hat it is satisfied for both helicity conserving and nonconserving parts. T he integrations are then performed for the explicit calculation of the impa ct factors in the massless quark case.
