Metric-affine bumblebee gravity: quantum aspects
Year: 2020
Type: preprint
Abstract: In this paper, we study the quantum aspects of the recently proposed \cite{Delhom:2019gxg} metric-affine version of the bumblebee gravity. We examine the one-loop corrections provided by minimally coupled spinor fields around a trivial as well as an arbitrary bumblebee background in the weak gravitational field limit. In this context, we examine the role played by the couplings between the bumblebee field and the spinor matter sources at the quantum level. In the arbitrary background case, these terms contribute to the effective potential of the bumblebee field which could, in principle, allow for a dynamical Lorentz symmetry breaking.
