 +====== TTP06-08 Dimensional Reduction applied to QCD at three and four loops ====== 
 +  
 +  
 +   <​hidden TTP06-08 ​ Dimensional Reduction applied to QCD at three and four loops >  Dimensional Reduction is applied to \qcd{} in order to compute various 
 +   ​renormalization constants in the \drbar{} 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 $\varepsilon$-scalars and the additional 
 +   ​couplings which have to be considered.
