Charged lepton mixing processes in 331 Models

Processes $τ\rightarrow lγ$, $τ\rightarrow lll$ with $l= e,μ$ and $μ(τ) \to e (μ) γ$ are evaluated in the framework of a model based on the extended symmetry gauge $SU(3)_c \otimes SU(3)_L \otimes U(1)_Y$ with a leptonic sector consistent 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.
