Real Time Thermal Propagators for Massive Gauge Bosons
نویسندگان
چکیده
We derive Feynman rules for gauge theories exhibiting spontaneous symmetry breaking using the real-time formalism of finite temperature field theory. We also derive the thermal propagators where only the physical degrees of freedom are given thermal boundary conditions. We analyse the abelian Higgs model and find that these new propagators simplify the calculation of the thermal contribution to the self energy.

On the Origin of Mass in Field Theory
The problem of mass origin in field theory lies in accounting for a quantum field theory with massive vector bosons out of a classical field theory which is both gauge invariant and massless. The possibility is here considered that, instead of assuming the existence of Higgs bosons, the very process of generating the correct action for the quantum theory allows for generation of massive terms i...
متن کاملAnalytic structure of the self-energy for massive gauge bosons at finite temperature.
We show that the one-loop self-energy at finite temperature has a unique limit as the external momentum pμ → 0 if the loop involves propagators with distinct masses. This naturally arises in theories involving particles with different masses as is demonstrated for a toy model of two scalars as well as in a U(1) Higgs theory. We show that, in spontaneously broken gauge theories, this observation...
متن کاملChiral fermions and gauge-fixing in five-dimensional theories
We study in detail the issue of gauge-fixing in theories with one universal extra dimension, i.e. theories where both bosons and fermions display Kaluza-Klein (KK) excitations. The extra dimension is compactified using the standard orbifold construction for a massless chiral fermion. We carry out the gauge-fixing procedure at the level of the five-dimensional theory and determine the tree-level...
متن کاملThermalisation of Longitudinal Gluons
In the usual real-time finite-temperature gauge theory both the physical and the unphysical degrees of freedom are thermalised. We discuss the alternative approach where only the physical transverse components of the gauge field have bare thermal propagators, whereas the unphysical degrees of freedom are not heated. We show how pinch singularities are avoided: sometimes this requires resummatio...
متن کاملGauge Field Model With Massive Gauge Bosons
[Abstract] A gauge field model, which simultaneously has strict local gauge symmetry and massive gauge bosons, is discussed in this paper. The model has SU(N) gauge symmetry. In the limit α −→ 0, the gauge field model discussed in this paper will return to Yang-Mills gauge field model. The important meaning of this model is that, without Higgs mechanism, gauge bosons can also obtain masses. Thi...
