Predictive scotogenic model with flavor dependent symmetry
Abstract In this paper, we propose a viable approach to realise two texture-zeros in the scotogenic model with flavor dependent $$U(1)_{B-2L_\alpha -L_\beta }$$ U(1)B-2Lα-Lβ gauge symmetry. These models are extended by two right-handed singlets $$N_{Ri}$$ NRi and two inert scalar doublets $$\eta _{i...

Abstract In this paper, we propose a viable approach to realise two texture-zeros in the scotogenic model with flavor dependent $$U(1)_{B-2L_\alpha -L_\beta }$$ U(1)B-2Lα-Lβ gauge symmetry. These models are extended by two right-handed singlets $$N_{Ri}$$ NRi and two inert scalar doublets $$\eta _{i}$$ ηi , which are odd under the dark $$Z_2$$ Z2 symmetry.
