We point out that, in a spontaneously broken U(1) gauge theory, inclusive processes, whose primary particles are mass eigenstates that do not coincide with the gauge eigenstates, are not free of infrared logarithms. The charge mixing allowed by symmetry breaking and the ensuing BlochNordsieck violation are here analyzed in a few relevant cases and in particular for processes initiated by longit...
متن کاملpropagators 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. PACS numbers: 11.15.-q, 11.30.Qc, 12.15.-y Typeset u...
متن کاملGoldstino Decoupling in Spontaneously Broken Supergravity Theories
If the gravitino is sufficiently light and stable it will behave as an effective massless neutrino species at the time of nucleosynthesis. Depending on the temperature at which it decouples from the thermal bath in the early universe, the gravitino mass will be bounded by the primordial 4He abundance. Assuming a conservative estimate that the number of neutrino families, Nν < 3.6, superlight gr...
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 کاملThe Bloch-nordsieck Propagator at Finite Temperature
We have shown recently that the resummation of soft photon contributions leads to a non-exponential decay of the fermion excitations in hot QED plasmas. The retarded propagator of a massless fermion was found to behave as SR(t 1/gT ) ∼ exp{−αTt [ lnωpt+C]}, where ωp = gT/3 is the plasma frequency, α = g2/4π, and C is a constant, independent of g, which was left undefined. This term is computed ...
