Radiative corrections to quark-quark-Reggeon vertex in QCD

Abstract

One loop corrections to the coupling of the Reggeized gluon to quarks are calculated in QCD. Combining this result with the known corrections to the gluon-gluon-Reggeon vertex, we check the self-consistency of the representation of the amplitudes with gluon quantum numbers and the negative signature in the t channel in terms of the Regge pole contribution.
