Lepton flavour violation in unparticle physics

Recently H. Georgi has introduced an unparticle U 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 μ−→e−e+e−, and found that the branching ratio of this decay is strongly dependent on the scaling dimension.
