| ====== 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. |
