Flavour and CP predictions from orbifold compactification

We propose a theory for fermion masses and mixings in which an A 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...

Resumo:We propose a theory for fermion masses and mixings in which an A 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≃+268. The effective neutrinoless double-beta decay mass parameter is also sharply predicted as 〈m〉≃2.65meV.
