Abstract

We predict the contribution of scalar unparticle to the branching ratios of the lepton flavor conserving Z -> l(+)l(-) decays and we study the discrepancy between the experimental and the QED corrected standard model branching ratios. We observe that these decays are sensitive to the unparticle scaling dimension d(u) for its small values, especially for heavy lepton flavor output.
