Abstract

The 3-3-1 model with neutral leptons exists a source of lepton -flavor-violating (LFV) due to oscillations of active neutrinos and the mixing of exotic leptons. The investigation of component contributions for l_i -> l_j \gamma  helps to select the parameter space regions which suitable with the current experimental data. We show that, in the parameter space regions where Br(\mu -> e\gamma)   satisfies the experimental limits,  Br(\tau -> e\gamma) and  Br(\tau -> \mu\gamma) are also smaller than the upper bound of the experimental data.
