We present a model based on the SU(3)C⊗SU(3)L⊗U(1)X
gauge symmetry having an extra T7⊗Z2⊗Z3⊗Z14
flavor group, which successfully describes the observed SM fermion mass and
mixing pattern. In this framework, the light active neutrino masses arise via
double seesaw mechanism and the observed charged fermion mass and quark mixing
hierarchy is a consequence of the Z2⊗Z3⊗Z14 symmetry
breaking at very high energy. In our minimal T7 flavor 331 model, the
spectrum of neutrinos includes very light active neutrinos as well as heavy and
very heavy sterile neutrinos. The model has in total 16 effective free
parameters, which are fitted to reproduce the experimental values of the 18
physical observables in the quark and lepton sectors. The obtained physical
observables for both quark and lepton sectors are compatible with their
experimental values. The model predicts the effective Majorana neutrino mass
parameter of neutrinoless double beta decay to be 3 and
40 meV for the normal and the inverted neutrino spectrum, respectively.
Furthermore, our model features a vanishing leptonic Dirac CP violating phase.Comment: 18 pages. Final version. To be published in Journal of Physics G.
