Prospects for SME Tests with Experiments at SYRTE and LKB

TL;DR

This paper discusses the potential of atomic experiments at SYRTE and LKB to explore physics beyond the Standard Model and General Relativity, highlighting ongoing studies with the Microscope mission and Cs fountain clock.

Contribution

It presents preliminary assessments and ongoing studies of atomic experiments at SYRTE and LKB for fundamental physics tests beyond current models.

Findings

Cs fountain clock improves proton-sector coefficient $ar{c}_{TT}$ to $10^{-17}$ GeV

Ongoing experiments with Microscope mission and Cs fountain clock

Assessment of experimental prospects for new physics searches

Abstract

Preliminary work has been done in order to assess the perspectives of metrology and fundamental physics atomic experiments at SYRTE and LKB in the search for physics beyond the Standard Model and General Relativity. The first studies we identified are currently ongoing with the Microscope mission and with a Cs fountain clock. The latter brings significant improvement on the proton-sector coefficient $\bar{c}_{TT}$ down to the $10^{-17}$ GeV level.
