Abstract We propose a theory for fermion masses and mixings in which an A 4 family symmetry arises naturally from a six-dimensional spacetime after orbifold compactification. The flavour symmetry leads to the successful “golden” quark-lepton unification formula. The model reproduces oscillation parameters with good precision, giving sharp predictions for the CP violating phases of quarks and leptons, in particular δ l ≃ + 268 ∘ . The effective neutrinoless double-beta decay mass parameter is… Expand
