A Common Origin for Diverse Neutrino Mass Matrix Textures

Manash Dey, Pralay Chakraborty, Dipshikha Das, Subhankar Roy

Abstract

We plan to decipher the common origin of neutrino mass textures within a $Δ(27)$ based framework, in association with Type-I+II seesaw mechanism. Motivated by the diversity of texture structures used in phenomenological analyses, we examine how a single framework can reproduce them without additional assumptions. We show that the interplay between vacuum alignments, model parameters, and specific Yukawa choices naturally yields several well established neutrino mass textures in the literature. Our goal is to demonstrate that a minimal $Δ(27)$ framework can unify these viable textures within a common theoretical origin.
