Abstract
We examine current Large Hadron Collider constraints on some simple $Z'$
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 $Z'$ boson is
less than 300 GeV.

The current recommendation prototype on the Apollo Repository will be turned off on 03 February 2023. Although the pilot has been fruitful for both parties, the service provider IKVA is focusing on horizon scanning products and so the recommender service can no longer be supported. We recognise the importance of recommender services in supporting research discovery and are evaluating offerings from other service providers.
