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 of master integrals and numerically in Landau gauge. They can be used to reduce the errors in determinations of baryonic distribution amplitudes in lattice QCD simulations. & COPY; 2023 The Author(s). Published by Elsevier B.V.
