To the problem on the Universe evolution and the condensed description in the field theory

TL;DR

This paper proposes a field theory approach to universe evolution, suggesting that vector boson masses vary over time, which could explain the hot early universe without relying on expansion hypotheses.

Contribution

It introduces a new Lagrangian framework that derives a massive vector boson propagator and links boson mass variation to universe evolution.

Findings

Vector boson masses depend on time.

The model explains the hot early universe without expansion.

A new Lagrangian formulation is proposed.

Abstract

On the basis of hypotheses, that a density of weakly interacting particles in the Universe has an order of nuclear matter density or more the Lagrangian is offered, through which one can be obtained a propagator of a vector boson with a non-zero rest-mass. The dependence of vector bosons masses on the time allows to explain the availability of the hot stage of the Universe evolution, not using to the hypothesis of the Universe expansion.
