摘要：

We compute the virtual next-to-leading corrections to the Lipatov vertex in the helicity-amplitude formalism. These agree with previous results by Fadin and collaborators, in the conventional dimensional-regularization scheme. We discuss the choice of Reggeization scale in order to minimize its impact on the next-to-leading-logarithmic corrections to the BFKL equation. [S0556-2821(99)02605-3].
