摘要In the supersymmetric seesaw model, large flavor mixings of sleptons induce the lepton flavor violating (LFV) interactions l(I)(l) over bar V-J (V=gamma,Z), which give rise to various LFV processes. In this work we examine the LFV decays Z-->l(I)(l) over bar (J). Subject to the constraints from the existing neutrino oscillation data and the experimental bounds on the decays l(J)-->l(Igamma), these LFV Z-decays are found to be sizable, and among them the largest-rate channel Z-->tau(μ) over bar can occur with a branching ratio of 10(-8) and may be accessible at the LHC or GigaZ experiment.
