CHARGED LEPTON MIXING PROCESSES IN 331 MODELS

Processes tau -> l(gamma), tau -> lll with l = e, mu and mu(tau) -> e(mu)(gamma) are evaluated in the framework of a model based on the extended symmetry gauge SU(3)(c) circle times SU(3)(L) circle times U(1)(Y) with a leptonic sector consisting of five triplets. Lepton flavor violating processes are allowed at tree level in this model through the new Z' gauge boson. We obtained bounds for the mixing angles in the leptonic sector of the model, considering the experimental measurements of the processes from the BELLE and the BABAR collaborations.
