Description
Massive neutrino is a clear evidence of new physics beyond the Standard Model. One of a well motivated new physics scenario is a model with gauged lepton flavor symmetry. We investigate neutrino properties in the minimal SU$(3)_\ell\times$SU$(3)_E$ gauged lepton flavor model. In this model, three new species of fermions are introduced to cancel gauge anomalies. These new fermions lead to a see-saw mechanism for neutrino mass generation. We impose the positivity of gauge boson masses and the perturbative unitarity in 2-2 scattering processes constraints to obtain viable neutrino spectrum.
