| Abstract: | ![]()
In the supersymmetric seesaw model, large flavor mixings of sleptons induce the lepton flavor violating (LFV) interactions  ( ), which give rise to various LFV processes. In this work we examine the LFV decays  . Subject to the constraints from the existing neutrino oscillation data and the experimental bounds on the decays  , these LFV Z-decays are found to be sizable, and among them the largest-rate channel  can occur with a branching ratio of 10-8 and may be accessible at the LHC or GigaZ experiment.Received: 1 September 2003, Published online: 20 November 2003 |
