Three-loop ?-functions and two-loop anomalous dimensions for MSSM regularized by higher covariant derivatives in an arbitrary supersymmetric subtraction scheme

Three-loop anomalous dimensions for squarks in supersymmetric QCD

In this paper we evaluate the renormalization constants and anomalous dimensions for the squark wave function and mass within supersymmetric QCD. These results complement the ones obtained in Ref. [1] and thus provide further confirmation on the applicability of dimensional reduction to supersymmetric QCD at three-loop order. The three-loop anomalous dimension constitute important input to prec...

Three-loop β-function for N = 1 supersymmetric electrodynamics, regularized by higher derivatives.

Three-loop β-function for N = 1 supersymmetric electrodynamics, regularized by higher derivatives. Abstract Three-loop quantum corrections to the effective action are calculated for N = 1 supersymmetric electrodynamics, regularized by higher derivatives. Using the obtained results we investigate the anomaly puzzle in the considered model.

Two-loop Renormalization of N = 1 Supersymmetric Electrodynamics, Regularized by Higher Derivatives

Two-loop β-function and anomalous dimension are calculated for N = 1 su-persymmetric quantum electrodynamics, regularized by higher derivatives. The result for two-loop contribution to β-function appears to be equal to 0, does not depend on the form of regularizing term and does not lead to anomaly puzzle. Two-loop anomalous dimension can be also made independent on parameters of higher derivat...

electrodynamics, regularized by higher derivatives.

Two-loop renormalization of N = 1 supersymmetric electrodynamics, regularized by higher derivatives. Abstract Two-loop β-function and anomalous dimension are calculated for N = 1 supersymmetric quantum electrodynamics, regularized by higher derivatives in the minimal subtraction scheme. The result for two-loop contribution to the β-function appears to be equal to 0, does not depend on the form ...
