Structures of the massive vector boson propagators at finite temperature illuminated by the Goldstone equivalence gauge
Abstract Inspired by the Goldstone equivalence gauge, we study the thermal corrections to an originally massive vector boson by checking the poles and branch cuts. We find that part of the Goldstone boson is spewed out from the longitudinal polarization, becoming a branch cut which can be approximat...
