Non-zero

We consider a model based on $$A_4$$ symmetry to explain the phenomenon of neutrino mixing. The spontaneous symmetry breaking of $$A_4$$ symmetry leads to a co-bimaximal mixing matrix at leading order. We consider the effect of higher order corrections in neutrino sector and find that the mixing angles thus obtained, come well within the $$3\sigma$$ ranges of their experimental values. We study the implications of this formalism on the other phenomenological observables, such as CP violating phase, Jarlskog invariant and the effective Majorana mass $$|M_{ee}|$$. We also obtain the branching ratio of the lepton flavour violating decay $$\mu \rightarrow e \gamma$$ in the context of this model and find that it can be less than its present experimental upper bound
