Investigating the universality of five-point QCD scattering amplitudes at high energy (Q6700651)

We provide various analytic results for one- and two-loop five-point QCD scattering amplitudes in multi-Regge kinematics (MRK).If you use the results distributed with this repository in your research work, please cite 2411.14050.This repository contains two archives: mrk_results.tar.gz: all the analytic results in Mathematica readable format are collected here. For a detailed description of their content and the notation adopted see README file in this archive. expansions_n4lp.tar.gz: in this archive the expansions of the one- and two-loop massless pentagon functions up to N^4LP are provided (see section 2 of the paper for a detailed description of the beyond leading-power expansion). Different expansions are performed in the upper and lower z-complex plane (see section of 2 of the paper). It further contains a Mathematica script, README.wl, which serves both as a description and example file.
