CPT and Lorentz tests with muons

TL;DR

This paper discusses how precision muon experiments can test for CPT and Lorentz violations at extremely high sensitivity levels, potentially revealing new physics beyond current theories.

Contribution

It proposes analyzing existing muon data to establish new, highly sensitive limits on CPT and Lorentz violation parameters.

Findings

Potential CPT and Lorentz violation limits at 4×10^{-21} and 10^{-23}

Existing muon data can be reanalyzed for fundamental symmetry tests

Enhanced sensitivity in fundamental symmetry testing with muons

Abstract

Precision experiments with muons are sensitive to Planck-scale CPT and Lorentz violation that is undetectable in other tests. Existing data on the muonium ground-state hyperfine structure and on the muon anomalous magnetic moment could be analyzed to provide dimensionless figures of merit for CPT and Lorentz violation at the levels of $4\times 10^{-21}$ and $10^{-23}$.
