B − L extension of the standard model with Q6 symmetry

Abstract

We propose a renormalizable B−L Standard Model (SM) extension based on Q6 symmetry which accommodates fermion mass and mixing parameters. Both normal and inverted neutrino mass orderings, the smallness of the active neutrino masses are generated through type I seesaw mechanism. The obtained physical parameters are well consistent with the global fit of neutrino oscillation [1] while the quark masses are in good agreement with the recent experimental data [2]. The model also predicts effective neutrino mass parameters of 〈mee〉=3.23×10−3 eV, mβ=8.92×10−3 eV for normal hierarchy (NH) and 〈mee〉=mβ=4.96×10−2 eV for inverted hierarchy (IH) which are all well consistent with the recent experiments.
