The electroweak model with rarely interacted neutrinos

TL;DR

This paper proposes a modified electroweak model with a contracted gauge group to naturally explain the rare interactions of neutrinos and their energy-dependent cross-sections.

Contribution

It introduces a novel electroweak model with a contracted gauge group that accounts for neutrino interaction properties in a natural way.

Findings

Neutrinos interact very rarely with matter.

Neutrino cross-section increases with energy.

The model relates the contraction parameter to the Fermi constant.

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 $j^2\approx 10^{-5}$.
