A bstract We use S 4 discrete group to construct a neutrino flavour model which leads to TM
1 mixing and is consistent with the neutrino oscillation data. Using the model's constrained …

A bstract We propose a complex extension of μτ permutation antisymmetry in the neutrino
Majorana matrix M ν. The latter can be realized for the Lagrangian by appropriate CP …

A bstract Within the framework of residual symmetry, two ℤ 2 type associate μτ inter-change
symmetries robustly constrain the Dirac CP phase δ in a model independent way. Both of …

We propose a complex extension of mixed μ τ antisymmetry in the neutrino Majorana mass
matrix M ν. This can be implemented in the Lagrangian by a generalized CP transformation …

A bstract We investigate the consequences of a generalized ℤ 2× ℤ 2 symmetry on a scaling
neutrino Majorana mass matrix. It enables us to determine definite analytical relations …

The residual symmetry approach, along with a complex extension for some flavor
invariance, is a powerful tool to uncover the flavor structure of the 3 *× 3 neutrino Majorana …

We present a systematic study on minimally perturbed neutrino mass matrices which at the
leading order give rise to Tri-BiMaximal (TBM) mixing due to a residual Bbb Z 2× Bbb Z 2 μτ …

Several important questions remain open in the field of neutrino oscillation physics,
including the possibility of CP-violation in the lepton sector, the ordering of the neutrino …

Superheavy neutrinos can, via the seesaw model, provide a mechanism for lepton number
violation. If they are combined with flavor violation as characterized by the Froggatt–Nielsen …

In a residual Z _2 * Z _2 symmetry approach, we investigate minimally perturbed Majorana
neutrino mass matrices. Constraint relations among the low energy neutrino parameters are …
