Abstract
We examine current Large Hadron Collider constraints on some simple Z models that significantly improve on Standard Model fits to b → sμ+μ− transition data. The models that we consider are the ‘third family baryon number minus second family lepton number’ (B3 − L2) model and the ‘third family hypercharge’ model and variants. The constraints are applied on parameter regions of each model that fit the b → sμ+μ− transition data and come from highmass 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 B3 − L2 model when the mass of the Z boson is less than 300 GeV.
