“…The G 1 pattern is excluded from observations of the neutrino oscillation (best-fit values), dark matter relic abundance and branching ratio of µ → eγ in the parameter space in Eq. (50). If we expand the model parameter space and/or we allow 3σ data of neutrino oscillation experiment instead of best-fit values, some points in G 1 pattern might become consistent with observations.…”

As the first topic, we propose a new parametrization of the complex Yukawa matrix in the scotogenic model. The new parametrization is compatible with the particle data group parametrization of the neutrino sector. Some analytical expressions for the neutrino masses with the new parametrization are shown. As the second topic, we consider the phenomenology of the socotogenic model with the one-zero-textures of the neutrino flavor mass matrix. One of the six patterns of the neutrino mass matrix is favorable for the real Yukawa matrix. On the other hand, for the complex Yukawa matrix, five of the six patterns are compatible with observations of the neutrino oscillations, dark matter relic abundance and branching ratio of the µ → eγ process.

We extend the notion of super-Minkowski space-time to include Z n 2 -graded (Majorana) spinor coordinates. Our choice of the grading leads to spinor coordinates that are nilpotent but commute amongst themselves. The mathematical framework we employ is the recently developed category of Z n 2 -manifolds understood as locally ringed spaces. The formalism we present resembles N -extended superspace (in the presence of central charges), but with some subtle differences due to the exotic nature of the grading employed.

In this paper, we propose a viable approach to realise two texture-zeros in the scotogenic model with flavor dependent U (1) B−2Lα−L β gauge symmetry. These models are extended by two righthanded singlets N Ri and two inert scalar doublets η i , which are odd under the dark Z 2 symmetry.Among all the six constructed textures, texture A 1 and A 2 are the only two allowed by current experimental limits. Then choosing texture A 1 derived from U (1) B−2Le−Lτ , we perform a detail analysis on the corresponding phenomenology such as predictions of neutrino mixing parameters, lepton flavor violation, dark matter and collider signatures. One distinct nature of such model is that the structure of Yukawa couplingLηN R is fixed by neutrino oscillation data, and can be further tested by measuring the branching ratios of charged scalars η ± 1,2 .
