Neutrino masses and lepton flavor violation in the 3-3-1 model with right-handed neutrinos

P.V. Dong and H. N. Long

We show that, in the 3-3-1 model with right-handed neutrinos, small neutrino masses and large lepton flavor violating processes such as \mu->3e and \mu->e\gamma can be obtained by just introducing an additional Higgs sextet. In the limit of vanishing of the Yukawa interaction among Higgs and lepton triplets h^\nu=0, the decay \mu->3e strongly depends on the neutrino-mass patterns, but the \mu->e\gamma almost does not. The neutrino masses are not constrained by such processes in the cases of h^\nu/=0.
