Neutrino masses from discrete gauge symmetries

High Energy Physics - Phenomenology 2009-10-22 v1

Abstract

We investigate a model with an extra Z2Z_{2} gauge symmetry in the Standard Model. We assume that only the scalars and the leptons carry non-zero charge. The symmetry gives a structure to the mass matrix for the neutrinos. With two extra Higgs singlets and two extra singlet right-handed neutrinos we can build a model that fits the requirements of the MSW-solution of the Solar neutrino problem. With a third singlet right-handed neutrino it is also possible to have a 10 eV neutrino, a dark matter candidate.
