On the link between finite QFT and standard RG approaches

Y. A. Ageeva, A. L. Kataev

A finite formulation of quantum field theory based on a system of differential equations reminiscent of the Callan-Symanzik equations is discussed. This system of equations was pre…

Exact relations between running of $I^\pm_{s}$ and $I^\pm$ in $N = 1$ SQCD+SQED

A. L. Kataev, K. V. Stepanyantz

In $N = 1$ 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…
