Effective action for high energy scattering in QCD
arXiv:hep-th/9311159
Abstract
The effective action for the multi-Regge asymptotics is considered as a first step in calculating the unitarity correction to the perturbative pomeron. It can be derived from the original QCD action by intgrating out certain modes of the fields in the functional integral. The derivation is described for the case without fermions.
