What do we know about Lorentz Symmetry?

TL;DR

This paper reviews recent experimental efforts to test Lorentz symmetry in gravity, highlighting new constraints and the potential of short-range tests to detect unexplored signals related to Lorentz violation.

Contribution

It provides an overview of recent analyses constraining Lorentz violation in gravity and emphasizes the significance of short-range tests in detecting new signals.

Findings

Constraints on Lorentz violation have been improved in various gravitational tests.

Short-range gravity experiments are sensitive to sidereal time-dependent signals.

New unexplored signals related to Lorentz violation may be detectable with current experiments.

Abstract

Precision tests of Lorentz symmetry have become increasingly of interest to the broader gravitational and high-energy physics communities. In this talk, recent work on violations of local Lorentz invariance in gravity is discussed, including recent analysis constraining Lorentz violation in a variety of gravitational tests. The arena of short-range tests of gravity is highlighted, demonstrating that such tests are sensitive to a broad class of unexplored signals that depend on sidereal time and the geometry of the experiment.
