propagators in spontaneously broken gauge theories
Contrary to common belief, the longitudinal vector meson and scalar meson propagators have very different forms in spontaneously broken gauge theories. We choose the Abelian-Higgs model as an example and show that the longitudinal vector meson and scalar meson propagators have double poles by an extensive use of the Ward-Takahashi identities.

متن کاملNoncommutativity and Spontaneously Broken Gauge Theories
We examine the spontaneous symmetry breaking of gauge theories in the framework of noncommutative field theory. We consider a noncommutative U(2) Higgs model with matter in the adjoint representation, that is the simplest example of a noncom-mutative gauge theory that is both classically well-defined in R ξ gauges and has an interacting commutative limit. In the ungauged global limit, the quant...
متن کاملObservables and Gauge Fixing in Spontaneously Broken Gauge Theories
Gauge fixing and the observable fields for both abelian and non-abelian gauge theories with spontaneous breaking of gauge symmetry are studied. We explicitly show that it is possible to globally fix the gauge in the broken sector and hence construct physical fields even in the non-abelian theory. We predict that any high temperature restoration of gauge symmetry will be accompanied by a confini...
متن کاملSpontaneously Broken Gauge Theories of Weak Interactions and Heavy Leptons
Branching ratios and production cross sections are calculated for the heavy leptons which occur in a class of spontaneously broken gauge theories of weak interactions. Several examples of such theories are constructed. (Submitted to Phys. Rev. ) * Supported by the U. S. Atomic Energy Commission. t Address after August 15, 1972: CERN, Geneva, Switzerland.
متن کاملNew gauge for computing effective potentials in spontaneously broken gauge theories.
A new class of renormalizable gauges is introduced that is particularly well suited to compute effective potentials in spontaneously broken gauge theories. It allows one to keep free gauge parameters when computing the effective potential from vacuum graphs or tadpoles without encountering mixed propagators of would-be-Goldstone bosons and longitudinal modes of the gauge field. As an illustrati...
