The Renormalizable B-L Model with D.sub.5 Discrete Symmetry for Lepton Masses and Mixings

We construct a renormalizable B-L standard model (SM) extension with D.sub.5 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 oscill...

Description
Summary:We construct a renormalizable B-L standard model (SM) extension with D.sub.5 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 â©m.sub.ee⪠= 3.731 x 10.sup.-3 eV for normal hierarchy (NH) and â©m.sub.ee⪠= 4.848 x 10.sup.-2 eV for inverted hierarchy (IH) which are well consistent with the recent experimental limits on neutrinoless double beta decay.
