Radiative generation of realistic neutrino mixing with A4
Radiative generation of realistic mixing in neutrino sector is studied at one-loop level in a scotogenic A4×Z2 symmetric framework. A scheme of obtaining non-zero θ13 through small mass splitting in right-handed neutrino sector is proposed. The model consists of three right-handed neutrinos, two of...

Radiative generation of realistic mixing in neutrino sector is studied at one-loop level in a scotogenic A4×Z2 symmetric framework. A scheme of obtaining non-zero θ13 through small mass splitting in right-handed neutrino sector is proposed. The model consists of three right-handed neutrinos, two of which were required to be degenerate in masses to yield the common structure of the left-handed neutrino mass matrix that corresponds to θ13=0, θ23=π/4 and any θ120 in particular the choices specific to the Tribimaximal (TBM), Bimaximal (BM) and Golden Ratio (GR) mixings. Non-zero θ13, deviations of θ23 from maximality and small corrections to the solar mixing angle θ12 can be generated in one stroke by shifting from this degeneracy in the right-handed neutrino sector by a small amount. The lightest among the three Z2 odd inert SU(2)L doublet scalars present in the model can be a potential dark matter candidate. |
