Abstract
Abstract: We examine current collider constraints on some simple Z′ models that fit neutral current B-anomalies, including constraints coming from measurements of Standard Model (SM) signatures at the LHC. The ‘MDM’ simplified model is not constrained by the SM measurements but is strongly constrained by a 139 fb−1 13 TeV ATLAS di-muon search. Constraints upon the ‘MUM’ simplified model are much weaker. A combination of the current Bs mixing constraint and ATLAS’ Z′ search implies MZ′>1.2 TeV in the Third Family Hypercharge Model example case. LHC SM measurements rule out a portion of the parameter space of the model for MZ′>1.5 TeV.
