Two-loop parameter relations between dimensional regularization and dimensional reduction applied to SUSY-QCD
arXiv:0908.3403 · doi:10.1016/j.physletb.2009.09.058
Abstract
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.
