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 B$_{s}$ mixing constraint and ATLAS’ Z$^{′}$ search implies $ {M}_{Z^{\prime }}>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 $ {M}_{Z^{\prime }}>1.5 $ TeV.
