Abstract:

This remark is part of an ongoing project to simplify the structure of the multi-loop anomalous dimensions for parton distributions and fragmentation functions. It answers the call for a structural explanation of a very suggestive relation found by Moch, Vermaseren and Vogt in the context of the x->1 behaviour of three-loop DIS anomalous dimensions. It also highlights further structure that remains to be fully explained.

quantum chromodynamics: perturbation theory
parton: momentum spectrum
fragmentation function
anomalous dimension
Feynman graph: higher-order
renormalization group
