# Combined Search for a Lorentz-Violating Force in Short-Range Gravity Varying as the Inverse Sixth Power of Distance

## TL;DR

This paper combines data from two experiments to test Lorentz symmetry in short-range gravity, setting new limits on potential violations of the inverse sixth power law with no observed effects.

## Contribution

It provides the first combined analysis of multiple experiments to constrain all 22 coefficients for Lorentz violation in short-range gravity.

## Key findings

- No Lorentz-violating effects detected at the $10^{-12}$ level.
- Set simultaneous limits on all 22 coefficients for Lorentz violation.
- Results are consistent with the standard inverse-square law.

## Abstract

Precision measurements of the inverse-square law via experiments on short-range gravity provide sensitive tests of Lorentz symmetry. A combined analysis of data from experiments at the Huazhong University of Science and Technology and Indiana University sets simultaneous limits on all 22 coefficients for Lorentz violation correcting the Newton force law as the inverse sixth power of distance. Results are consistent with no effect at the level of $10^{-12}$ m$^{4}$.
