A non-perturbative argument for the non-abelian Higgs mechanism
Giacomo De Palma, Franco Strocchi
TL;DR
This paper provides a rigorous non-perturbative proof that the non-abelian Higgs mechanism prevents the emergence of massless Goldstone bosons, confirming the mechanism's consistency beyond perturbation theory.
Contribution
It introduces a non-perturbative argument in the local BRST gauge to establish the Higgs mechanism's effectiveness in non-abelian gauge theories.
Findings
Goldstone bosons are evaded non-perturbatively
The proof is based on BRST gauge formalism
Supports the theoretical foundation of the Higgs mechanism
Abstract
The evasion of massless Goldstone bosons by the non-abelian Higgs mechanism is proved by a non-perturbative argument in the local BRST gauge.
