Neutrinoless double beta decay in a flavor symmetric Scotogenic model
We have studied the scotogenic model proposed by Ernest Ma, wherein the Standard Model is extended by three singlet right handed neutrinos and a scalar doublet. This model proposes that the light neutrinos acquire a non-zero mass at 1-loop level. We have done a A_4×Z_4 realisation of the scotogenic model in this framework. This model results in the production of non-zero θ_13 by the assumption of a non-degeneracy in the right handed neutrino masses. We have further studied the 0νββ in the model by the consideration of constraints from neutrino oscillation data and KamLAND-Zen limit.
