The electroweak model with rarely interacted neutrinos

Abstract

The electroweak model, which lepton sector correspond to the contracted gauge group $ SU(2;j)\times U(1), j \rightarrow 0 $, whereas boson and quark sectors are standard one, is suggested. This model describe in a natural manner why neutrinos so rarely interact with matter, as well as why neutrinos cross-section increase with the energy. Dimensionfull parameter of the model is interpreted as neutrino energy. Dimensionless contraction parameter $j$ for low energy is connected with the Fermi constant of weak interactions and is approximated as $j^2\approx 10^{-5}$.
