Abstract

We consider the renormalization of the three-quark operators without derivatives at next-to-next-toleading order in QCD perturbation theory at the symmetric subtraction point. This allows us to obtain conversion factors between the MS scheme and the regularization invariant symmetric MOM (RI/SMOM, RI �/SMOM) schemes. The results are presented both analytically in R & xi; gauge in terms of a set ...
