Analog of Electroweak Model for Contracted Gauge Group

TL;DR

This paper explores a limiting case of the Electroweak Model where the gauge group is contracted, leading to a scenario where certain bosons become external fields and particle masses remain unchanged.

Contribution

It introduces a contracted gauge group version of the Electroweak Model and analyzes the behavior of bosons and particle masses in this limit.

Findings

Higgs, Z, and electromagnetic fields become external to W-bosons.

W-bosons do not influence external fields.

Particle masses remain invariant under the contraction.

Abstract

The limiting case of the bosonic part of the standard Electroweak Model, which correspond to the contracted gauge group $ SU(2;j)\times U(1)$ is discussed. The Higgs boson, Z-boson and electromagnetic fields become an external ones with respect to the W-bosons fields. The W-bosons fields do not effect on these external fields. The masses of the all particles of the Electroweak Model remain the same under contraction.
