Description
In this talk, we will discuss the 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. Using this framework we study, in the high-energy limit and at larger transverse distances the transition to a much simpler effective local Reggeon field theory, and investigate the critical properties. Moreover, we perform numerical analysis of the spectrum of the BFKL Pomeron by the introduction of a Wilsonian infrared regulator to understand the properties of the leading poles (Pomeron states) and its contribution to the high-energy scattering
