Lepton Flavour Violation in Unparticle Physics

TL;DR

This paper investigates how unparticle physics, a scale-invariant sector, affects lepton flavor violation, specifically the decay rmu^- ^- e^+ e^-, showing the decay rate depends heavily on the unparticle's scaling dimension.

Contribution

It explores the phenomenology of unparticles in lepton flavor violating processes, highlighting the dependence of decay rates on the unparticle's scaling dimension.

Findings

Branching ratio varies significantly with the unparticle's scaling dimension.

Unparticle effects could potentially be observed in lepton flavor violating decays.

The study provides constraints on unparticle parameters from decay data.

Abstract

Recently H. Georgi has introduced an unparticle $\unpart$ in order to describe the low energy physics of a nontrivial scale invariant sector of an effective theory. In this work we have explored the phenomenology of an unparticle using the lepton flavour violating decay $\mu^{-}\to e^{-} e^{+} e^{-}$, and found that the branching ratio of this decay is strongly dependent on the scaling dimension.
