Lepton Flavor Violation in a $Z^{\prime }$ model for the $b\to s$ anomalies

Abstract

In recent years, several observables associated to semileptonic $b\to s$ processes have been found to depart from their predicted values in the Standard Model, including a few tantalizing hints of lepton flavor universality violation. In this work we consider an existing model with a massive $Z^{\prime }$ boson that addresses the anomalies in $b\to s$ transitions and extend it with a non-trivial embedding of neutrino masses. We analyze lepton flavor violating effects, induced by the non-universal interaction associated to the $b\to s$ anomalies and by the new physics associated to the neutrino mass generation, and determine the expected ranges for the most relevant observables.
