Description
Summary:By construction, gauge theories require gauge fixing. In conventional approaches to spontaneously broken gauge theories, the choice of the Unitary ('t Hooft) gauge involves the sacrifice of manifest renormalizability (unitarity). It is shown that with a suitable modification of the background field gauge condition, the background field formalism allows manifest unitarity and renormalizability in a single framework.
