摘要：

Recent experimental results suggest that the neutrinos of the Standard Model are massive, though light. Therefore they may mix with each other giving rise to lepton flavour or even lepton number violating processes, depending on whether they are Dirac or Majorana particles. Furthermore, the lightness of the observed neutrinos may be explained by the existence of heavy ones, whose effects on LFV would be very sizeable. We present an analysis of the effect of massive neutrinos on flavour-changing decays of the Z boson into leptons, at the one-loop level, independent of neutrino mass models. Constraints from present experiments are taken into account.
