We study the effective action describing high-energy scattering processes in the multi-Regge limit of QCD, which should provide the starting point for a new attempt to overcome the limitations of the leading logarithmic and the eikonal approximations. The action can be obtained via simple graphical rules or by integrating in the QCD functional integral over momentum modes of gluon and quark fields that do not appear explicitly as scattering or exchanged particles in the considered processes. The supersymmetry is used to obtain the terms in the action involving quark fields from the pure gluonic ones. We observe Weizsaecker-Williams-type relations between terms describing scattering and production of particles.
