Abstract

We propose a renormalizable T' flavor model based on the SU(3)(C) x SU(3)(L) xU(1)(X) x U(1)(L) gauge symmetry, consistent with the observed pattern of lepton masses and mixings. The small masses of the light active neutrinos are produced from an interplay of type I and type II seesaw mechanisms, which are induced by three heavy right-handed Majorana neutrinos and three SU(3)( L) scalar antisextets, respectively. Our model is only viable for the scenario of normal neutrino mass hierarchy, where the obtained physical observables of the lepton sector are highly consistent with the current neutrino oscillation experimental data. In addition, our model also predicts an effective Majorana neutrino mass parameter of m(beta) similar to 1.41541 x 10(-2) eV, a Jarlskog invariant of the order of J(CP) similar to-0.032 and a leptonic Dirac CP violating phase of delta= 238 degrees, which is inside the 1 sigma experimentally allowed range.
