TTP07-13 Dimensional reduction applied to QCD at three loops.
Recent developments in higher order calculations within the framework of
Dimensional Reduction, the preferred regularization scheme for
supersymmetric theories, are reported on. Special emphasis is put on the
treatment of evanescent couplings, the equivalence to Dimensional
Regularization, and the evaluation of $\alpha_s(M_{\rm GUT})$ from
$\alpha_s(M_{\rm Z})$.
