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.

Comments: The actual oscillation distance is the distance between the neutrino flavor eigenstate and the muon. This was not made clear in the article
