In particular, the $\beta$ function and the + ​anomalous dimension of the quark masses are derived to three-loop + ​order. Special emphasis is put on the proper + ​treatment of the so-called $\varepsilon$-scalars and the additional + ​couplings which have to be considered. + ​ + |**R. Harlander, P. Kant, L. Mihaila, M.
