Four-loop collinear anomalous dimensions in QCD and $\mathcal{N}=4$ super Yang-Mills

Abstract

We calculate the collinear anomalous dimensions in massless four-loop QCD and $\mathcal{N}=4$ supersymmetric Yang-Mills theory from the infrared poles of vertex form factors. We give very precise numerical approximations and a conjecture for the complete analytic results in both models we consider.
