The model predicts that a TeV-scale $$Z^\prime$$ Z should decay to particle-antiparticle pairs of muons, taus, top quarks and bottom quarks with appreciable branching ratios. We reinterpret various ATLAS and CMS search limits for $$Z^\prime$$ Z production followed by such decays at the LHC over a parameter space of the model that results from a successful combined fit to the $$b\rightarrow s l^+ l^-$$ b s l + l - data and precision electroweak observables. Current exclusions in parameter space and expected sensitivities of the various different channels in the high-luminosity run are compared. We find that the high-luminosity run of the LHC will significantly increase the sensitivity to the model beyond the existing empirical limits, which we find to be surprisingly weak. dc.language en dc.publisher Springer Science and Business Media LLC dc.subject Regular Article - Theoretical Physics dc.title Hide and seek with the third family hypercharge model’s Z at the large hadron collider dc.type Article dc.date.updated 2022-04-01T16:00:35Z prism.issueIdentifier 3 prism.publicationName European Physical Journal C prism.volume 82 dc.identifier.doi 10.17863/CAM.83108 dcterms.dateAccepted 2022-03-07 rioxxterms.versionofrecord 10.1140/epjc/s10052-022-10191-6 rioxxterms.version VoR rioxxterms.licenseref.uri http://creativecommons.org/licenses/by/4.0/ dc.identifier.eissn 1434-6052 pubs.funder-project-id Science and Technology Facilities Council (ST/P000681/1) pubs.funder-project-id STFC (ST/T000694/1) cam.issuedOnline 2022-03-31
