 +   <​hidden TTP06-27 ​ Four-loop $\beta$ function and anomalous mass dimension in Dimensional Reduction > Within the framework of QCD we compute renormalization constants for the 
 + ​strong coupling and the quark masses to four-loop order. We apply the 
 + ​DR-bar scheme and put special emphasis on the additional couplings which 
 + have to be taken into account. This concerns the epsilon-scalar--quark 
 + ​Yukawa coupling as well as the vertex containing four epsilon-scalars. 
 + For a supersymmetric Yang Mills theory, we find, in contrast to a 
 + ​previous claim, that the evanescent Yukawa coupling equals the strong 
 + ​coupling constant through three loops as required by supersymmetry.
