Neutrinos are Dirac fermions with masses arising only in two-loop order through the sector responsible for dark matter. Two triality symmetries ensure both dark matter stability and strict lepton number conservation at higher orders. A global spontaneously broken U(1) symmetry leads to a physical Diraconthat induces invisible Higgs decays which add up to the Higgs to dark matter mode. This enhances sensitivities to spin-independent WIMP dark matter search below m(h)/2. %K Neutrino masses and mixing %K Dark matter stability %R 10.1016/j.physletb.2016.09.027 %U http://arxiv.org/abs/1607.03931 %U https://doi.org/10.1016/j.physletb.2016.09.027 %P 214-218
