We discuss the dependence of running couplings on the choice of regularization method in a general softly-broken N=1 supersymmetric theory. Regularization by dimensional reduction respects supersymmetry, but standard dimensional regularization does not. We find expressions for the differences between running couplings in the modified minimal subtraction schemes of these two regularization methods, to one loop order. We also find the two-loop renormalization group equations for gaugino masses in both schemes, and discuss the application of these results to the Minimal Supersymmetric Standard Model.

Original abstract

We discuss the dependence of running couplings on the choice of regularization method in a general softly-broken N=1 supersymmetric theory. Regularization by dimensional reduction respects supersymmetry, but standard dimensional regularization does not. We find expressions for the differences between running couplings in the modified minimal subtraction schemes of these two regularization methods, to one loop order. We also find the two-loop renormalization group equations for gaugino masses in both schemes, and discuss the application of these results to the Minimal Supersymmetric Standard Model.

The procedure to incorporate the supersymmetric effects on the numerical value of $sin^2Θ^(6),MS(M_Z)$ is as follows: In a first step we transfer $sin^2Θ^(6),MS(M_Z)$ from Eq. ([ref]) to the scheme [ref] and apply afterwards the supersymmetric one-loop corrections evaluated in Ref. [ref] relating the weak mixing angle in the SM to the one in MSSM.
