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.
