How to test SME with space missions ?

TL;DR

This paper explores how data from Cassini and Messenger space missions can be used to test and constrain coefficients in the Standard-Model Extension (SME), enhancing our understanding of fundamental physics.

Contribution

It presents simulations of radioscience observables within the SME framework and identifies the sensitivity of these datasets to SME coefficients.

Findings

Cassini and Messenger data are highly effective for constraining SME coefficients.

The study identifies specific linear combinations of SME coefficients that observations depend on.

Simulations demonstrate the potential to improve bounds on SME parameters.

Abstract

In this communication, we focus on possibilities to constrain SME coefficients using Cassini and Messenger data. We present simulations of radioscience observables within the framework of the SME, identify the linear combinations of SME coefficients the observations depend on and determine the sensitivity of these measurements to the SME coefficients. We show that these datasets are very powerful for constraining SME coefficients.
