Abstract

We propose two new predictive neutrino mass matrix textures that deviate from μ-τ symmetry and explore their phenomenological implications. These textures are significant due to their predictive nature and the unique approach they introduce for breaking the μ-τ symmetry. Both textures predict six physical parameters and impose sharp constraints on θ₂₃ and δ, considering both normal and inverted neutrino mass orderings. In addition, we realize the textures in their exact form within the framework of the seesaw mechanism, based on the SU(2)_L × A₄ × Z₃ symmetry group.
