Lorentz Symmetry Derived from Lorentz Violation in the Bulk

TL;DR

This paper explores how Lorentz violation in bulk fields influences Lorentz symmetry constraints on brane physics and the cosmological constant, suggesting a link between bulk Lorentz violation and observable brane phenomena.

Contribution

It introduces a framework connecting bulk Lorentz violation to constraints on brane Lorentz symmetry and the cosmological constant, providing new insights into bulk-brane interactions.

Findings

Lorentz violation in the bulk affects brane Lorentz symmetry.

Constraints on the cosmological constant arise from Lorentz symmetry requirements.

Bulk field interactions influence observable brane physics.

Abstract

We consider bulk fields coupled to the graviton in a Lorentz violating fashion. We expect that the overly tested Lorentz symmetry might set constraints on the induced Lorentz violation in the brane, and hence on the dynamics of the interaction of bulk fields on the brane. We also use the requirement for Lorentz symmetry to constrain the cosmological constant observed on the brane.
