Abstract

We study the radiative lepton flavor violating l(i) -> l(j)gamma gamma decays in the case that the lepton flavor violation is induced by the scalar unparticle mediation. We restrict the scaling dimension d(u) and the scalar unparticle photon-photon coupling by using the experimental upper limit of the branching ratio of the decay mu -> c gamma gamma. Furthermore, we predict the BRs of the other radiative decays by using the restrictions we get. We observe that the measurements of upper limits of BRs of these decays ensure considerable information for testing the possible signals coming from unparticle physics.
