Lepton Flavour Violating Z Decays in the MSSM

The possibility to observe lepton flavour violating Z decays in the GigaZ option of DESY’s TESLA project consistently with present bounds from other processes is analyzed in the context of the minimal supersymmetric standard model. In particular, constraints on the slepton mass matrices from radiative lepton decays are updated and taken into account. Their correlation to the present measurement of the muon anomalous dipole moment is briefly discussed.
