The breaking of $\mu-\tau$ reflection symmetry in a $B-L$ model with $(Z_2\times Z_4)\rtimes Z_2\, (II)$ symmetry

We present a neutrino mass model based on %non-Abelian discrete symmetry $(Z_2\times Z_4)\rtimes Z_2\, (\mathrm{II})$ which successfully accounts for the observed neutrino oscillation data. The atmospheric mixing angle is predicted to be in the higher octant with $\theta_{23}^{(\circ)}\in (47.80, \, 49.40)$ and the predicted range of Dirac CP phase belongs to the lower half plane with $\delta_{CP}^{(\circ)}\in (273, \, 358)$. The hierarchy of lepton masses is naturally achieved and the constraints on the effective neutrino mass is consistent with the recent experimental limits.
