Natural Limits of Electroweak Model as Contraction of its Gauge Group

TL;DR

This paper derives the energy-dependent limits of the Electroweak Model through gauge group contraction, explaining neutrino interactions and early Universe conditions from fundamental principles.

Contribution

It introduces a gauge group contraction framework to analyze the Electroweak Model's behavior at different energy scales from first principles.

Findings

Neutrino-matter interactions weaken as energy decreases.

At infinite energy, particles become massless and interactions are mediated by neutral currents.

The model describes the early Universe from the Big Bang to one second after.

Abstract

The low and higher energy limits of the Electroweak Model are obtained from first principles of gauge theory. Both limits are given by the same contraction of the gauge group, but for the different consistent rescalings of the field space. Mathematical contraction parameter in both cases is interpreted as energy. The very weak neutrino-matter interactions is explained by zero tending contraction parameter, which depend on neutrino energy. The second consistent rescaling corresponds to the higher energy limit of the Electroweak Model. At the infinite energy all particles lose masses, electroweak interactions become long-range and are mediated by the neutral currents. The limit model represents the development of the early Universe from the Big Bang up to the end of the first second.
