  • We derive explicit transformation formulae relating the renormalized quark mass and field as defined in the MS-scheme with the corresponding quantities defined in any other scheme. By analytically computing the three-loop quark propagator in the high-energy limit (that is keeping only massless terms and terms of first order in the quark mass) we find the NNNLO conversion factors transforming the MS quark mass and the renormalized quark field to those defined in a “Regularization Invariant” (RI… CONTINUE READING
