Relation between leading divergences in nonrenormalizable supersymmetric theories
Ali Lakhal, Konstantin Stepanyantz
We consider an nonrenormalizable supersymmetric gauge theory with the superpotential quartic in the chiral matter superfields. With the help of the Slavnov's higher co…
Three-loop verification of the equations relating running of the gauge couplings in SQCD+SQED
Olesya Haneychuk, Konstantin Stepanyantz
We verify a recently derived equations relating the renormalization group running of two gauge couplings in SQCD+SQED by the explicit three-loop calculation. It is dem…
On two-loop divergences of effective action in , SYM theory
I. L. Buchbinder, E. A. Ivanov, B. S. Merzlikin +1
We study the off-shell structure of the two-loop effective action in supersymmetric gauge theories formulated in harmonic superspace. The off-…
Three-loop -functions and two-loop anomalous dimensions for MSSM regularized by higher covariant derivatives in an arbitrary supersymmetric subtraction scheme
Olesya Haneychuk, Valentina Shirokova, Konstantin Stepanyantz
Three-loop -functions of the Minimal Supersymmetric Standard Model regularized by higher covariant derivatives are obtained for an arbitrary supersymmetric subtraction scheme. F…
The three-loop anomalous dimension and the four-loop -function for SQED regularized by higher derivatives
Ilya Shirokov, Konstantin Stepanyantz
For SQED with flavors regularized by higher derivatives in the general -gauge we calculate the three-loop anomalous dimension of the matter superfields define…
The -function of supersymmetric theories from vacuum supergraphs: a three-loop example
Sergei Aleshin, Ivan Goriachuk, Dmitry Kolupaev +1
We verify a method which allows to obtain the -function of supersymmetric theories regularized by higher covariant derivatives by calculating only specially modified vacuum supe…
