====== TTP09-29 Two-loop parameter relations between dimensional regularization and dimensional reduction applied to SUSY-QCD ====== The two-loop relations between the running gluino-quark-squark coupling, the gluino and the quark mass defined in dimensional regularization (DREG) and dimensional reduction (DRED) in the framework of SUSY-QCD are presented. Furthermore, we verify with the help of these relations that the three-loop beta-functions derived in the minimal subtraction scheme combined with DREG or DRED transform into each other. This result confirms the equivalence of the two schemes through three-loops, if applied to SUSY-QCD. |**Luminita Mihaila** | |** Phys.Lett.
