Lepton mass and mixing in a Neutrino Mass Model based on $S_4$ flavor symmetry

We study a neutrino mass model based on $S_4$ flavor symmetry which accommodates lepton mass, mixing with non-zero $θ_{13}$ and CP violation phase. The spontaneous symmetry breaking in the model is imposed to obtain the realistic neutrino mass and mixing pattern at the tree- level with renormalizable interactions. Indeed, the neutrinos get small masses from one $SU(2)_L$ doubplet and two $SU(2)_L$ singlets in which one being in $\underline{2}$ and the two others in $\underline{3}$ under $S_4$ with both the breakings $S_{4}\rightarrow S_3$ and $S_{4}\rightarrow Z_3$ are taken place in charged lepton sector and $S_4\rightarrow \mathcal{K}$ in neutrino sector. The model also gives a remarkable prediction of Dirac CP violation $δ_{CP}=\fracπ{2}$ or $-\fracπ{2}$ in the both normal and inverted spectrum which is still missing in the neutrino mixing matrix. The relation between lepton mixing angles is also represented.
