Two loop renormalization of the n = 2 Wilson operator in the RI'/SMOM scheme
Published 10 Mar 2011 in hep-ph and hep-lat | (1103.2055v1)
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.
