Radiative corrections to quark-quark-Reggeon vertex in QCD.

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 negative signature in the t-channel in terms of Regge pole contribution. 1. Introduction Since a long time it has been found [1] that, in the leading logarithmic approximation (LLA) for the Regge region, the total cross section σ
