Popis: | We construct a renormalizable B–L standard model (SM) extension with D5 symmetry in which neutrino mass hierarchies and the tiny neutrino masses are generated at leading order by type I seesaw mechanism. The obtained physical parameters are well consistent with the global fit of neutrino oscillation data given in [1]. The model predicts an effective neutrino mass parameter of 〈mee〉 = 3.731 × 10–3 eV for normal hierarchy (NH) and 〈mee〉 = 4.848 × 10–2 eV for inverted hierarchy (IH) which are well consistent with the recent experimental limits on neutrinoless double beta decay. |
