Lepton Flavour Violation in Unparticle Physics

Abstract

Recently H. Georgi has introduced an unparticle $\text{unpart}$ 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.
