Chiral symmetry and form factors of neutrino-nucleon interactions

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 (FF) G A (Q 2 ) considered as multipole expansion multiplied on pQCD asymptotes is in a good agreement with experimental data.
