摘要The most stringent bounds on the anomalous magnetic and electric dipole moments of the tau lepton were derived by Escribano and Mass6 [6] from the Z width at LEP in an effective lagrangian approach to the new physics, The new interactions are assumed to act dominantly on the tau lepton. In this paper we point out that the higher dimensional operators introduced by Escribano and Mass6 not only notify the neutral currents of the tau lepton to Z gauge boson and the photon, but also induce lepton flavor violation (LFV). The size of the LFV effect depends crucially on the dynamics of the lepton mass generation. Assuming the lepton mass matrices in the form of an Fritzsch ansatz, we point out that the experimental limit on mu --> e gamma will push the anomalous magnetic and electric dipole moments of the tau lepton down to 10(-11) and 10(-25) e cm respectively.
