New Solutions for RG Equations in QCD
R. M. Iakhibbaev, D. I. Kazakov, D. M. Tolkachev
We construct simple analytical solutions of renormalization group equations for the running coupling and for the Green functions in QCD in the asymptotic regime. These solutions ha…
Effective Potential in Subleading Logarithmic Approximation in Arbitrary Non-renormalizable Scalar Field Theory
R. M. Iakhibbaev, D. I. Kazakov, A. I. Mukhaeva +1
Following the previously developed approach to the calculation of quantum corrections to the effective potential in arbitrary scalar field theories in the leading logarithmic appro…
Chiral effective potential in , SYM theory
I. L. Buchbinder, R. M. Iakhibbaev, D. I. Kazakov +2
We consider , , super Yang-Mills theory formulated in terms of superfields where the leading low-energy contributions to effective action…
Chiral effective potential in , supersymmetric gauge theories
I. L. Buchbinder, R. M. Iakhibbaev, A. I. Mukhaeva +2
We calculate the chiral effective superpotential in , super Yang-Mills theory coupled to chiral matter in one- and two-loop approximations. It is found…
Loop corrections to the four-fermion interaction
A. T. Borlakov, D. I. Kazakov
We consider the f f to f f scattering amplitudes for the a massless four-fermion interaction model in four dimensions. At first we take the simplest version with the scalar current…
Dark energy due to quantum corrections to effective potential
V. A. Filippov, R. M. Iakhibbaev, D. I. Kazakov +1
In this paper we calculate quantum corrections to the effective potential in different models of inflationary cosmology. We show that quantum corrections lead to a modification of…
