Abstract: A number of DR-bar renormalization constants in softly broken SUSY-QCD areevaluated to three-loop level: the wave function renormalization constants forquarks, squarks, gluons, gluinos, ghosts, and epsilon-scalars, and therenormalization constants for the quark and gluino mass as well as for allcubic vertices. The latter allow us to derive the corresponding beta functionsthrough three loops, all of which we find to be identical to the expression forthe gauge beta function obtained by Jack, Jones, and North Jack:1996vg seealso Ref. Pickering:2001aq. This explicitely demonstrates the consistency ofDRED with SUSY and gauge invariance, an important pre-requisite for precisioncalculations in supersymmetric theories.
