Constraints on Covariant Horava-Lifshitz Gravity from frame-dragging experiment

TL;DR

This paper investigates how Horava-Lifshitz gravity modifications affect frame-dragging phenomena and uses satellite data to constrain the theory's parameters within the weak field, slow motion regime.

Contribution

It provides the first detailed analysis of Horava-Lifshitz gravity effects on gravito-magnetic fields using real experimental data from satellite missions.

Findings

Constraints on Horava-Lifshitz parameters derived from satellite experiments.

Compatibility of Horava-Lifshitz gravity with current frame-dragging measurements.

Potential for future terrestrial experiments to further test the theory.

Abstract

The effects of Horava-Lifshitz corrections to the gravito-magnetic field are analyzed. Solutions in the weak field, slow motion limit, referring to the motion of a satellite around the Earth are considered. The post-newtonian paradigm is used to evaluate constraints on the Horava-Lifshitz parameter space from current satellite and terrestrial experiments data. In particular, we focus on GRAVITY PROBE B, LAGEOS and the more recent LARES mission, as well as a forthcoming terrestrial project, GINGER.
