New Hybrid Textures for Neutrino Mass Matrices

Understand

We perform a systematic investigation of the texture structures of Majorana neutrino mass matrix $M_{\nu}$ having two texture zeros and an equality between two nonzero matrix elements, in the light of recent neutrino oscillation data.

• Among forty-two possible textures, it is found that only eight textures are compatible with the current experimental data at 3$\sigma$ C.L.
• Out of these phenomenologically viable textures, six follow normal mass ordering while remaining two satisfy the inverted mass ordering of neutrino mass spectrum.
• In the numerical analysis, we carry out a scan over the possible space of all viable patterns.
