Remarks on Muon $g-2$ Experiments and Possible CP Violation in $\pi\to\mu\to e$ Decay

TL;DR

This paper discusses the implications of CERN g-2 experiment results for CP violation in pion decay processes, providing initial experimental limits on such violations.

Contribution

It presents the first experimental limit on CP violation in pion decay derived from existing CERN g-2 data, highlighting potential new physics insights.

Findings

Established the first experimental limit on CP violation in pion decay

Linked CERN g-2 results to CP violation constraints

Suggested avenues for future CP violation studies in meson decays

Abstract

The first experimental limit on CP violation in pi -> mu -> e decay is extracted from published results of the CERN g-2 experiment.
