Description
We remind the BFKL approach to the high energy QCD. It is based on calculations of production amplitudes in the multi-Regge kinematics, where the results are expressed in terms of reggeized gluons and their interactions. The effective field theory for scattering amplitudes with the multi-Regge unitarity is constructed for gauge theories and gravity. More general effective actions describing the quasi-multi-Regge processes in these models are also discussed.
