On the quantum equivalence of an antisymmetric tensor field with spontaneous Lorentz violation

preprint2020arXivOpen access

Abstract

We present an explicit proof that a minimal model of rank-2 antisymmetric field with spontaneous Lorentz violation and a classically equivalent vector field model are also quantum equivalent, by calculating quantum effective actions of both theories. We comment on the issues encountered while checking quantum equivalence in curved spacetime.
