摘要：

Radiative corrections to QCD amplitudes in the quasi-multi-Regge kinematics are interesting, in particular, since the Reggeized form of these amplitudes is used in the derivation of the NLO BFKL. This form is a hypothesis which must be at least carefully checked, if not proved. We calculate the radiative corrections in the one-loop approximation using the delta-channel unitarity. Compatibility of the Reggeized form of the amplitudes with the s-channel unitarity requires fulfillment of the set of nonlinear equations for the Reggeon vertices. We show that these equations are satisfied. (C) 2004 MAIK "Nauka/lnterperiodica".
