چکیده
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.

متن کاملTwo-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...

Summation of diagrams in N = 1 supersymmetric electrodynamics, regularized by higher derivatives. Abstract For the massless N = 1 supersymmetric electrodynamics, regularized by higher derivatives, the Feynman diagrams, which define the divergent part of the two-point Green function and can not be found from Schwinger-Dyson equations and Ward identities, are partially summed. The result can be w...

Investigation of the anomaly puzzle in N = 1 supersymmetric electrodynamics. Abstract Using Schwinger-Dyson equations and Ward identities in N = 1 supersym-metric electrodynamics, regularized by higher derivatives, we find, that it is possible to calculate some contributions to the two-point Green function of the gauge field and to the β-function exactly to all orders of the perturbation theory...

A method of Feynman diagrams summation, based on using Schwinger-Dyson equations and Ward identities, is verified by calculating some four-loop diagrams in N = 1 supersymmetric electrodynamics, regularized by higher derivatives. In particular, for the considered diagrams correctness of an additional identity for Green functions, which is not reduced to the gauge Ward identity, is proved.
