Unparticles and Muon Decay

TL;DR

This paper explores how hypothetical unparticles could induce lepton flavor violation, particularly affecting muon decay processes, and demonstrates that muon decay experiments are highly sensitive to detecting such phenomena.

Contribution

It introduces the potential impact of unparticles on muon decay and analyzes the sensitivity of current and future experiments to these effects.

Findings

Muon decay experiments can probe unparticle interactions.

Unparticles provide a new source of lepton flavor violation.

Current experiments already constrain unparticle parameter space.

Abstract

Recently Georgi has discussed the possible existence of `Unparticles' describable by operators having non-integral scaling dimensions. With the interaction of these with the Standard Model (SM) particles being constrained only by gauge and Lorentz symmetries, it affords a new source for lepton flavour violation. Current and future muon decay experiments are shown to be very sensitive to such scenarios.
