The present evidence for neutrino masses and lepton flavor mixings allows us to predict, in the standard model with light neutrinos, the branching rates for the decays \stackrel\ensuremath→Ze\ensuremathμ, \ensuremathμ\ensuremathτ, e\ensuremathτ of less than 10^\ensuremath-54, while present experimental exclusion limits from CERN LEP 1 are of the order of 10^\ensuremath-5. The GigaZ option of the TESLA Linear Collider project will extend the sensitivity down to about 10^\ensuremath-8. We study in a systematic way some minimal extensions of the standard model and show that GigaZ might well be sensitive to the rates predicted from these scenarios.
