Universality of QCD traveling-waves with running coupling beyond leading logarithmic accuracy

TL;DR

This paper demonstrates that in high-energy QCD with running coupling, the universal asymptotic behavior of solutions is unaffected by Next-to-Leading-Logarithmic and higher order corrections, emphasizing the robustness of traveling-wave solutions.

Contribution

It provides a general argument that NLL and higher order terms do not influence the universal asymptotic features of QCD evolution equations with saturation and running coupling.

Findings

NLL and higher order terms are irrelevant for asymptotic solutions

Universal traveling-wave solutions are robust against higher order corrections

High-energy QCD evolution exhibits universal behavior regardless of NLL contributions

Abstract

We discuss the solutions of QCD evolution equations with saturation in the high energy limit. We present a general argument showing that, in the running coupling case, the Next-to-Leading-Logarithmic (NLL) and higher order terms are irrelevant for the universal asymptotic features of the solutions.
