Description
In this work, a flavour theory, of a neutrino mass model implementing an $A_4$ family symmetry is proposed. This scheme provides a simple way to derive tribimaximal mixing in the neutrino sector via spontaneous breaking of $A_4 $ symmetric model leading to acceptable values of $\theta_{13}$ and maximal CP violation. A $z_2 \times z_2$ invariant perturbations in this model is introduced in the neutrino sector which leads to testable predictions of $\theta_{13}$ and CP violation. By changing the magnitudes of perturbations in neutrino sector, one can generate viable values of $\theta_{13}$ and neutrino oscillation parameters.
