Short-range gravity and Lorentz violation

TL;DR

This paper explores how short-range gravity experiments can detect violations of local Lorentz invariance, revealing new signals influenced by experimental setup and sidereal time.

Contribution

It demonstrates that short-range gravity tests can probe a wide range of previously unconstrained Lorentz-violating signals in the pure-gravity sector.

Findings

Short-range gravity experiments are sensitive to Lorentz violation signals.

Experimental geometry and sidereal time affect the detection of violations.

New constraints on Lorentz invariance in gravity are suggested.

Abstract

Comparatively few searches have been performed for violations of local Lorentz invariance in the pure-gravity sector. We show that tests of short-range gravity are sensitive to a broad class of unconstrained and novel signals that depend on the experimental geometry and on sidereal time.
