Asymptotic Freedom of V-A Fermi Interaction
A. T. Borlakov, D. I. Kazakov
We consider the V-A Fermi interaction and apply an earlier developed method for summing up the leading asymptotics for scattering amplitudes in non-renormalizable theories. We cons…

High-energy behaviour of Fermi theory
A. T. Borlakov, D. I. Kazakov
We consider the 4-fermion scattering amplitude in massless Fermi theory. Based on the Bogolyubov-Parasyuk theorem, which guarantees locality of the counter terms, we derive the rec…

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…
