Cobimaximal Neutrino Mixing from $S_3\times Z_2$

Abstract

It has recently been shown that the phenomenologically successful pattern of cobimaximal neutrino mixing (${\theta }_{13}\ne 0$, ${\theta }_{23}=\pi /4$, and ${\delta }_{CP}=\pm \pi /2$) may be achieved in the context of the non-Abelian discrete symmetry $A_4$. In this paper, the same goal is achieved with $S_3\times Z_2$. The residual lepton $Z_3$ triality in the case of $A_4$ is replaced here by $Z_2\times Z_2$. The associated phenomenology of the scalar sector is discussed.
