Absolute neutrino mass scale and dark matter stability from flavour symmetry

A bstract We explore a simple but extremely predictive extension of the scotogenic model. promote symmetry ? 2 to flavour non-Abelian ?(81), which can also automatically protect dark matter stability. In addition, ?(81) leads striking predictions in lepton sector: only Inverted Ordering is realised, absolute neutrino mass scale predicted be m lightest ? 7 . 5 × 10 ? 4 eV and Majorana phases are correlated such way that |m ee | 0 018 eV. The model strong correlation between solar mixing angle ? 12 ? CP , may falsified by next generation oscillation experiments. setup minimal sense no additional symmetries or flavons required.
