Abstract

In this paper, we propose a viable approach to realise two texture-zeros in the scotogenic model with flavor dependent U(1)B2LαLβU(1)_{B-2L_\alpha-L_\beta} gauge symmetry. These models are extended by two right-handed singlets NRiN_{Ri} and two inert scalar doublets ηi\eta_{i}, which are odd under the dark Z2Z_2 symmetry. Among all the six constructed textures, texture A1A_1 and A2A_2 are the only two allowed by current experimental limits. Then choosing texture A1A_1 derived from U(1)B2LeLτU(1)_{B-2L_e-L_\tau}, we perform a detail analysis on the corresponding phenomenology such as predictions of neutrino mixing parameters, lepton flavor violation, dark matter and collider signatures. One distinct nature of such model is that the structure of Yukawa coupling Lˉη~NR\bar{L}\tilde{\eta}N_R is fixed by neutrino oscillation data, and can be further tested by measuring the branching ratios of charged scalars η1,2±\eta_{1,2}^\pm.
