Relation between dimensional reduction and dimensional regularization to two loops — •Jonas Kleine — TTP Karlsruhe

Within supersymmetric theories one uses in general dimensional reduction (DRED) in order to regularize the occurring divergences. However, quite often it is convenient to apply dimensional regularization (DREG) for the practical evaluation of the Feynman integrals. Afterwards the transition to DRED is achieved by finite shifts of the parameters. In this talk we discuss for various couplings and masses the relation between DREG and DRED within supersymmetric QCD.
