A functional RG approach for the BFKL Pomeron

A functional RG approach for the BFKL Pomeron

Abstract In this paper we encode the perturbative BFKL leading logarithmic resummation, relevant for the Regge limit behavior of QCD scattering amplitudes, in the IR-regulated effective action which satisfies exact functional renormalization group equations. This is obtained using a truncation with...
