Abstract

We predict the branching ratios of the lepton-flavor violating Z-boson decays Z -> e(+/-)mu(+/-), Z -> e(+/-)tau(+/-) and Z -> mu +/-tau +/- in the case that the lepton-flavor violation is carried by scalar unparticlemediation. We observe that their BRs are strongly sensitive to the unparticle scaling dimension, and the branching ratios can reach values of the order of 10(-8), for the heavy lepton-flavor case, for small values of the scaling dimension.
