Parametrization invariance and the resolution of the unitary gauge puzzle
Parametrization invariance and the resolution of the unitary gauge puzzle
We examine the calculation of the critical temperature ${\mathit{T}}_{\mathit{c}}$ for the restoration of a spontaneously broken symmetry. Motivated by a set of recently developed gauge dependence identities, we give a gauge- and parametrization-independent definition of this temperature in terms of the physical mass of the scalar particle as determined by …
