摘要：
Dimensional Reduction is applied to QCD in order to compute various renormalization constants in the DR scheme at higher orders in perturbation theory. 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 epsilon-scalars and the additional couplings which have to be considered.
