Large Hadron Collider Constraints on Some Simple $Z^{\prime }$ Models for $b\to s{\mu }^{+}{\mu }^{-}$ Anomalies

Abstract

We examine current Large Hadron Collider constraints on some simple $Z^{\prime }$ models that significantly improve on Standard Model fits to $b\to s{\mu }^{+}{\mu }^{-}$ transition data. The models that we consider are the 'third family baryon number minus second family lepton number' $(B_3-L_2)$ model and the 'third family hypercharge' model and variants. The constraints are applied on parameter regions of each model that fit the $b\to s{\mu }^{+}{\mu }^{-}$ transition data and come from high-mass Drell-Yan di-muons and measurements of Standard Model processes. This latter set of observables place particularly strong bounds upon the parameter space of the $B_3-L_2$ model when the mass of the $Z^{\prime }$ boson is less than 300 GeV.
