TL;DR

This paper proposes a mechanism for dynamically generating mass in the SU(2) Georgi-Glashow model by considering vacuum configurations, leading to a specific gauge field propagator and spectrum.

Contribution

It introduces a new approach to mass generation in non-Abelian gauge theories based on vacuum configuration superpositions.

Findings

Derived the gauge field propagator in the model

Identified the one-particle spectrum with the SU(2) Georgi-Glashow model

Calculated in leading order of 1/d expansion

Abstract

A mechanism for the dynamical mass generation of a non-Abelian gauge field which is based on taking into account the contributions of the gauge field vacuum configurations into the formation of the physical vacuum is considered. For a model of the physical vacuum as a superposition of Abelian configurations the gauge field propagator is calculated in the leading order of $1/d$-expansion ($d$ is a space-time dimension). One-particle spectrum of the model corresponds to the gauge sector of SU(2) Georgi-Glashow model.
