Charged lepton mixing processes in 331 Models

Abstract

Processes $\tau \to l\gamma$, $\tau \to lll$ with $l=e,\mu$ and $\mu (\tau )\to e(\mu )\gamma$ 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 $Z^{\prime }$ 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.
