All-loop renormalization group invariants for MSSM
Daniil Rystsov, Konstantin Stepanyantz
For MSSM from the gauge couplings, Yukawa couplings, and the coefficient in the part of superpotential quadratic in the Higgs superfields we construct combinations which (for c…

Exact relations between running of and in SQCD+SQED
A. L. Kataev, K. V. Stepanyantz
In supersymmetric QCD-like theories we derive the (all-order) exact equations relating the renormalization group behaviour of the strong and electromagnetic couplings…

Algebraic structure of the renormalization group in the renormalizable QFT theories
Andrei Kataev, Konstantin Stepanyantz
We consider the group formed by finite renormalizations as an infinite-dimensional Lie group. It is demonstrated that for the finite renormalization of the gauge coupling constant…
