Implications of a class of neutrino mass matrices with texture zeros for non-zero $\theta_{13}$

TL;DR

This paper explores a specific class of neutrino mass matrices with texture zeros, showing they can naturally produce a non-zero θ13 and deviations from maximal mixing, aligning with recent experimental hints.

Contribution

It demonstrates that certain texture zero neutrino mass matrices based on Z3 symmetry can naturally account for non-zero θ13 within the type (I+II) seesaw framework.

Findings

The model admits a non-zero θ13 consistent with recent data.

Deviations from maximal mixing are naturally explained.

The phenomenology aligns with current experimental hints.

Abstract

A class of neutrino mass matrices with texture zeros realizable using the group $Z_3$ within the framework of type (I+II) seesaw mechanism naturally admits a non-zero $\theta_{13}$ and allows for deviations from maximal mixing. The phenomenology of this model is reexamined in the light of recent hints for non-zero $\theta_{13}$.
