Abstract

We compute the anomalous dimensions of the flavour non-singlet twist-2 Wilson operators in the RI′/SMOM scheme at two loops in an arbitrary linear covariant gauge. In addition we provide the full Green’s function for these operators inserted in a quark 2-point function at the symmetric subtraction point. The three loop anomalous dimensions in the Landau gauge are also derived.
