Muon Oscillations

Abstract

Muons produced via the $\pi \to \mu {\nu }_{\mu }$ decay are in a coherent superposition of energy states because the ${\nu }_{\mu }$ is not a mass eigenstate. This presents an opportunity to access neutrino mixing parameters via muon decay. The oscillation period is long compared to the muon lifetime which presents some experimental challenges.

arXiv commentThe actual oscillation distance is the distance between the neutrino flavor eigenstate and the muon. This was not made clear in the article
