In a recently proposed renormalizable model of neutrino mixing using the non-Abelian discrete symmetry T_7 in the context of a supersymmetric extension of the Standard Model with gauged U(1)_{B-L}, a correlation was obtained between theta_{13} and theta_{23} in the case where all parameters are real. Here we consider all parameters to be complex, thus allowing for one Dirac CP phase delta_{CP} and two Majorana CP phases alpha_{1,2}. We find a slight modification to this correlation as a function of delta_{CP}. For a given set of input values of Delta m^2_{21}, Delta m^2_{32}, theta_{12}, and theta_{13}, we obtain sin^2 2 theta_{23} and m_{ee} (the effective Majorana neutrino mass in neutrinoless double beta decay) as functions of tan delta_{CP}. We find that the structure of this model always yields small |tan delta_{CP}|.
We study a neutrino mass model based on $S_4$ flavor symmetry which accommodates lepton mass, mixing with non-zero $theta_{13}$ and CP violation phase. The spontaneous symmetry breaking in the model is imposed to obtain the realistic neutrino mass an
The latest measurements of the anomalous muon magnetic moment $a^{}_mu equiv (g^{}_mu - 2)/2$ show a $4.2sigma$ discrepancy between the theoretical prediction of the Standard Model and the experimental observations. In order to account for such a dis
A multiscalar and nonrenormalizable $B-L$ extension of the standard model (SM) with $S_4$ symmetry which successfully explains the recent observed neutrino oscillation data is proposed. The tiny neutrino masses and their hierarchies are generated via
We construct a multiscalar and nonrenormalizable $B-L$ model with $A_4times Z_3times Z_4$ flavor symmetry which successfully explains the recent $3+1$ active-sterile neutrino data. The tiny neutrino mass the mass hierarchy are obtained by the type-I
We discuss a classically conformal radiative neutrino model with gauged B$-$L symmetry, in which the B$-$L symmetry breaking can occur through the Coleman-Weinberg mechanism. As a result, Majorana mass term is generated and EW symmetry breaking also
