# Predictive Scotogenic Model with Flavor Dependent Symmetry

## TL;DR

This paper introduces a flavor-dependent gauge symmetry extension to the scotogenic model, predicting specific neutrino mixing, lepton flavor violation, dark matter properties, and collider signatures, with Yukawa couplings constrained by neutrino data.

## Contribution

It proposes a novel realization of texture-zero neutrino mass matrices within a flavor-dependent gauge symmetry framework, linking neutrino data to collider phenomenology.

## Key findings

- Texture A1 and A2 are compatible with experimental limits.
- Yukawa couplings are fixed by neutrino oscillation data.
- Model predicts measurable collider signatures and lepton flavor violation.

## Abstract

In this paper, we propose a viable approach to realise two texture-zeros in the scotogenic model with flavor dependent $U(1)_{B-2L_\alpha-L_\beta}$ gauge symmetry. These models are extended by two right-handed singlets $N_{Ri}$ and two inert scalar doublets $\eta_{i}$, which are odd under the dark $Z_2$ symmetry. Among all the six constructed textures, texture $A_1$ and $A_2$ are the only two allowed by current experimental limits. Then choosing texture $A_1$ derived from $U(1)_{B-2L_e-L_\tau}$, 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 $\bar{L}\tilde{\eta}N_R$ is fixed by neutrino oscillation data, and can be further tested by measuring the branching ratios of charged scalars $\eta_{1,2}^\pm$.
