Longitudinal loop integrals in the gauge invariant effective action for high energy QCD

Abstract

We study integrations over light-cone degrees of freedom in the gauge invariant effective action for high energy processes in QCD. We propose a regularization which takes into account the signature of the reggeized gluon. For a test we apply it to the elastic and the production amplitude.
