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

Gauge couplings evolution from the Standard Model, through Pati-Salam theory, into $E_8$ unification of families and forces
We explore the potential of ultimate unification of the Standard Model matter and gauge sectors into a single $E_8$ superfield in ten dimensions via an intermediate Pati-Salam gauge theory. Through aExpand
