Abstract

Near maximal neutrino mixing needed to understand atmospheric neutrino data can be interpreted to be a consequence of an interchange symmetry between the muon and tau neutrinos in the neutrino mass matrix in the flavor basis. This idea can be tested by a measurement of the neutrino mixing parameter θ₁₃ and looking for its correlation with θ₂₃ - π / 4. We present a supersymmetric SU(5) grand unified model for quarks and leptons which obeys this exchange symmetry and is a realistic model that can fit all observations. GUT embedding shifts θ₁₃ from its zero μ - τ symmetric value to a nonzero value keeping it under an upper limit.
