Searching Unparticle Signatures Through Tau Pair Production

Abstract

In this work, we study the possible unparticle signatures through tau pair production e+e- -> tau+tau- process at the low energy particle factories. We take into account lepton flavor conserving (s-channel) and violating (t-channel) couplings for the unparticle leptonic interactions. For different values of the scaling parameter d we extract upper limits on the scalar unparticle couplings at the integrated luminosities of 100/fb.yr and 1 ab/fb.yr.
