Constraining CP violation in a softly broken A4 symmetric model

To understand the mass spectra of charged lepton and neutrino A(4) symmetry has been proposed in addition with the standard SU(2)(L)xU(1)(Y) model. We break A(4) symmetry softly and the deviation from the tribimaximal mixing arises due to Zee mechanism. In the present work, we express two mixing angles theta(13) and theta(23), in terms of a single model parameter and experimental observables, such as, mixing angle theta(12), mass-squared differences Delta m(21)(2) and Delta m(32)(2). Using the experimental values of theta(23), theta(12), Delta m(21)(2), and Delta m(32)(2) we restrict the model parameter and we predict theta(13). This model gives rise to theta(13)similar or equal to 11 degrees if we allow 1 sigma deviation of theta(23) and 2 degrees deviation of theta(12) from their best fit values. Utilizing all those constraints, we explore the extent of CP violation parameter J(CP) in the present model and found a value of J(CP)approximate to 2.65x10(-3) (for 1 sigma deviation of theta(23) and 2 degrees deviation of theta(12)) consistent with the other neutrino experimental results. We have studied the mass pattern of neutrino and neutrinoless double beta decay (beta beta(0 nu)) parameter vertical bar(M-nu)(ee)vertical bar in this model.
