Muons, gravity and time

TL;DR

This paper discusses the effects of high radial acceleration on muons in storage rings, examining the implications of the equivalence principle and concluding it does not influence muon lifetime.

Contribution

It provides an analysis of gravitational effects on muons under extreme acceleration, clarifying the role of the equivalence principle in particle lifetime measurements.

Findings

Radial acceleration in muon storage rings is extremely large.

The equivalence principle predicts a gravity-like force on muons.

Muons' lifetime remains unaffected by the acceleration-induced gravity.

Abstract

In the muon storage rings the muons are subject to a very large radial acceleration. The equivalence principle implies a large gravity force. It has no effect on the muon lifetime.
