We endeavour to constrain the neutrino mass matrix on the phenomenological ground and procure model-independent textures by emphasizing on the simple linear relationships among the mass matrix elements. These simple textures predict the two Majorana phases. In this regard, two types of parametrization of neutrino mass matrix: general and exponential are employed. We obtain fifty-three predictive neutrino mass matrix textures, out of which twenty-eight are associated with the general parametrization, and the rest belong to the exponential one. Apart from Type-A/P textures, the rest deal with the prediction of a few other oscillation parameters as well. We try to realize the proposed textures in the light of $A_4$, $\Delta\,(27)$ and $T_7$ symmetry groups.

“…To construct a consistent neutrino mass model which respect both the electroweak gauge symmetry and the µ-τ permutation or reflection symmetry, it is in most cases unavoidable to introduce some additional scalar fields and require them to couple to the charged-lepton and neutrino sectors in quite different ways (see, e.g. [35,57,68,69] for details). In some viable models of this kind, such new hypothetical degrees of freedom may lead to rich phenomenology in particle physics and thus enhance their experimental testability.…”

The observed pattern of lepton ﬂavor mixing and CP violation strongly indicates the possible existence of a simple ﬂavor symmetry in the neutrino sector — the effective Majorana neutrino mass term keeps invariant when the three left-handed neutrino ﬁelds transform as νeL → (νeL)c, νµL → (ντL)c and ντL → (νµL)c. A direct application of such a µ-τ reﬂection symmetry to the canonical seesaw mechanism can help a lot to constrain the ﬂavor textures of active and sterile Majorana neutrinos. The present article is intended to summarize the latest progress made in exploring the properties of this minimal ﬂavor symmetry, its translational and rotational extensions, its soft breaking effects via radiative corrections from a superhigh energy scale to the electroweak scale, and its various phenomenological implications.
