A Four-Parameter Black-Hole Solution in the Bumblebee Gravity …

Bumblebee models are useful for exploring the effects of spontaneous Lorentz violation in gravitational theories. These effects include the existence of Nambu–Goldstone modes, massive (Higgs) modes, and the possibility of a Higgs mechanism. In bumblebee models, Lorentz and diffeomorphism symmetry are spontaneously broken, so these effects have to be considered in the context of both types of symmetry breaking.
