Abstract :
In the context of flavor-universal topcolor-assisted technicolor (TC2) models, we calculate the lepton flavor violating (LFV) Z→lilj decays. We find that the extra U(1) gauge boson Z′ can give significant contributions to these LFV processes. With reasonable values of the parameters, the branching ratios of the processes Z→τμ and Z→τe can approach the experimental upper limits. The indirect bound on the process Z→μe can give a severe constraint on the flavor-universal TC2 models.
