Abstract

We phenomenologically build a neutrino mass matrix obeying μ-τ symmetry with only two parameters, Cabibbo angle (λ) and a flavour twister parameter (η). For vanishing η, the model assumes TBM mixing. When η=λ, the model generates a solar mixing angle and solar mass squared difference that coincide with the experimental best-fits. It motivates us to propose a mixing matrix in the neutrino sector with sinθ₁₂
