Lepton Flavor Violation processes in 331 Models

Models based on the extended symmetry gauge $SU(3)_c \otimes SU(3)_L \otimes U(1)_Y$ can be build up with a leptonic sector consistent of five triplets in different $SU(3)_L$ representations where additional heavy fermions are included. Some of these models present flavor changing neutral currents in the leptonic sector which are mediated through the $Z'$ boson. One of these models is studied using the measurements of lepton flavor violation processes such as $τ\rightarrow lll$ with $l= e,μ$ and $μ(τ) \to e (μ) γ$.
