# Non-universal electroweak extensions of the standard model and the scotogenic models

## TL;DR

This paper explores non-universal $U(1)'$ gauge symmetry extensions of the standard model, combined with scotogenic models, to address low-energy experimental anomalies through new fermions and gauge interactions.

## Contribution

It introduces two novel non-universal solutions with additional fermions, expanding the framework for analyzing family-dependent anomalies.

## Key findings

- Identified two viable non-universal $U(1)'$ solutions
- Extended the scotogenic model with three neutral singlet Dirac fermions
- Provided a basis for analyzing family-dependent experimental anomalies

## Abstract

In order to analyze some low energy experimental anomalies, we charge with a non-universal $U(1)'$ gauge symmetry the standard model fermions, taking as a starting point the well-known scotogenic model. In order to have non-trivial solutions to the anomalies and the Yukawa constraints, we add three neutral singlet Dirac fermions. We have found two possible non-universal solutions which, as a matter of principle, are suitable to analyze family-dependent experimental anomalies.
