Title SO(10) x S4 Grand Unified Theory of Flavour
Abstract I present a Grand Unified Theory of Flavour, based on SO(10) together with a non-Abelian discrete group S4. The CSD2 flavon vacuum alignment is discussed. The Yukawa matrices are derived and neutrino masses emerge from the type I seesaw mechanism. A full numerical fit is performed with 15 input parameters generating 19 presently constrained observables. The model predicts a normal neutrino mass ordering with a CP oscillation phase of 260 degrees, an atmospheric angle in the first octant and neutrinoless double beta decay with m= 11 meV. I also discuss N2 leptogenesis, which fixes the second right-handed neutrino mass to be M2~ 2*10^11 GeV, in the natural range predicted by the model.
