TL;DR

This paper develops a phenomenological model for neutrino-nucleon interactions based on chiral symmetry and meson dominance, successfully describing weak nucleon form factors and matching experimental data.

Contribution

It introduces a multigauge model incorporating chiral symmetry and meson dominance to analyze neutrino-nucleon interactions and form factors.

Findings

Weak nucleon form factor $G_A(Q^2)$ agrees with experimental data.

Neutron beta decay constant relates to meson masses and hadronization parameters.

Model provides a good description of quasi-elastic neutrino scattering.

Abstract

Phenomenological multigauge model of neutrino-nucleon interaction based on chiral symmetry of strong interactions and vector/pseudovector meson dominance model is suggested. It was shown that within the framework of the model the constant of neutron beta decay is formed by meson masses and parameters of the hadronization of fundamental vector bosons. Then, quasi elastic (anti)neutrino-nucleon scattering processes have been investigated and it was found that weak nucleon form factor $G_A(Q^2)$ considered as multipole expansion multiplied on pQCD asymptotes is in a good agreement with experimental data.
