In this work, we have modified a scenario, originally proposed by Grimus and Lavoura, in order to obtain maximal values for atmospheric mixing angle and $CP$ violating Dirac phase of the lepton sector. To achieve this, we have employed $CP$ and some discrete symmetries in a type II seesaw model. In order to make predictions about neutrino mass ordering and the smallness of the reactor angle, we have obtained some conditions on the elements of the neutrino mass matrix of our model. Finally, within the framework of our model, we have studied quark masses and mixing pattern. Content from this work may be used under the terms of the Creative Commons Attribution 3.0 licence.

“…Though the mass matrix structure of quarks and charged leptons in our framework is similar to these mentioned references, the mass matrix texture has been motivated from different symmetry prospects. In addition to that, we incorpo-rated the neutrino sector within the same framework and could explain all the neutrino oscillation data by diagonalizing the mass matrix [13]. In our approach, due to CP symmetry, there is no CP-violating phases appearing in the model.…”

We present a model which employs CP ×Z 3 symmetries where quark mixing and charged leptons masses are explained by following some texture. To achieve neutrino mass and mixing, we write a non-renormalizable Lagrangian using type-II seesaw mechanism by assuming O(1) couplings predicting no CP violation. Then, we calculate the value of the couplings for both normal and inverted ordering of neutrino masses. We propose a mechanism of ultra-violet (UV) completion that motivates the higher dimensional Lagrangian in the neutrino sector. We also calculate the branching fraction of lepton flavor violating decays driven by triplet scalar for the model. Later, it is shown that the model can also accommodate maximal CP violation by breaking the CP symmetry spontaneously.

“…[12], after relaxing some of the assumptions made in Ref. [8] and also after using some approximation procedure [13], diagonalization has been done for the neutrino mass matrix of the MW model. Thereafter, it is concluded that both normal and inverted orderings for neutrino masses are possible in the MW model, apart from explaining the mixing pattern in neutrino sector.…”

We have considered a model, originally proposed by Ma and Wegman, where the mixing pattern in neutrino sector is explained with three Higgs doublets, six Higgs triplets and A 4 symmetry. The mixing pattern is explained with the help of vacuum expectation values (VEVs) of the above mentioned doublets and triplets. In order to study about the VEVs of the scalar fields, we construct the full invariant scalar potential of this model. After minimizing this scalar potential, we have demonstrated that, in order to consistently explain the neutrino mixing pattern, one has to introduce two more Higgs doublets into this model. To study some phenomenological implications of this model, we have worked out on the branching ratios for lepton flavor violating decays.
