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 $Z^{\mathrm{\prime }}$ boson. One of these models is studied using the measurements of lepton flavor violation processes such as $\tau \to lll$ with $l=e,\mu$ and $\mu (\tau )\to e(\mu )\gamma$.
