摘要：

We calculate the collinear anomalous dimensions in massless four-loop QCD and 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. (C) 2021 The Author(s). Published by Elsevier B.V.
