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

Abstract

In order to analyze some low energy experimental anomalies, we charge with a non-universal $U(1{)}^{\prime }$ 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.
