Could reggeon field theory be an effective theory for QCD in the Regge limit?

TL;DR

This paper explores whether reggeon field theory can effectively describe high-energy QCD interactions by analyzing its renormalization group flow and fixed points, aiming to establish its validity as an effective theory in the Regge limit.

Contribution

It provides a detailed analysis of the renormalization group equations for reggeon field theory and investigates the existence of fixed points, offering insights into its potential as an effective theory for QCD at high energies.

Findings

Identification of candidate fixed points in reggeon field theory

Analysis of the properties of the scaling solutions

Discussion of physical interpretations of the results

Abstract

In this paper we investigate the possibility whether, in the extreme limit of high energies and large transverse distances, reggeon field theory might serve as an effective theory of high energy scattering for strong interactions. We analyse the functional renormalization group equations (flow equations) of reggeon field theory and search for fixed points in the space of (local) reggeon field theories. We study in complementary ways the candidate for the scaling solution, investigate its main properties and briefly discuss possible physical interpretations.
