Lepton mass and mixing in a neutrino mass model based on S4 flavor symmetry

We study a neutrino mass model based on S-4 flavor symmetry which accommodates lepton mass, mixing with nonzero theta(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) doublet and two SU(2) L singlets in which one being in 2 and the two others in 3 under S-4 with both the breakings S-4 -> S-3 and S-4 -> Z(3) are taken place in charged lepton sector and S-4 -> K in neutrino sector. The model also gives a remarkable prediction of Dirac CP violation (CP)-C-delta = pi/2 or -pi/2 in both the normal and inverted spectrum which is still missing in the neutrino mixing matrix. The relation between lepton mixing angles is also represented.
