Description |
In this paper, we consider a neutrino mass model based on A(4) symmetry. The spontaneous symmetry breaking in this model is chosen to obtain tribimaximal mixing in the neutrino sector. We introduce Z(2) x Z(2) invariant perturbations in this model which can give rise to acceptable values of theta(13) and delta(CP). Perturbation in the charged lepton sector alone can lead to viable values of theta(13), but cannot generate delta(CP). Perturbation in the neutrino sector alone can lead to acceptable theta(13) and maximal CP violation. By adjusting the magnitudes of perturbations in both sectors, it is possible to obtain any value of delta(CP).
