Lepton flavor violating Z-boson decays at GigaZ as a probe of supersymmetry

Abstract

We briefly review the lepton flavor violating Z-decays at GigaZ as a probe of supersymmetry by focusing on $Z\to {\ell }_i{\overline{\ell }}_j$ in two representative supersymmetric models: the minimal supersymmetric model without R-parity and the supersymmetric seesaw model. We conclude that under the current experimental constraints from LEP and ${\ell }_i\to {\ell }_j\gamma$, these rare decays can still be enhanced to reach the sensitivity of the GigaZ. Therefore, supersymmetry can be probed via these decays at GigaZ.
