Combination of searches for heavy spin-1 resonances using 139 fb-1 of proton-proton collision data at SQUARE ROOTs = 13 TeV with the ATLAS detector

Popis výsledku v původním jazyce

A combination of searches for new heavy spin-1 resonances decaying into differentpairings of W, Z, or Higgs bosons, as well as directly into leptons or quarks, is presented.The data sample used corresponds to 139 fb-1 of proton-proton collisions at SQUARE ROOTs = 13TeV collected during 2015-2018 with the ATLAS detector at the CERN Large Hadron Collider. Analyses selecting quark pairs (qq, bb, t-t, and tb) or third-generation leptons (τν and τ τ ) are included in this kind of combination for the first time. A simplified model predicting a spin-1 heavy vector-boson triplet is used. Cross-section limits are set at the 95% confidence level and are compared with predictions for the benchmark model. These limits are also expressed in terms of constraints on couplings of the heavy vector-boson triplet to quarks, leptons, and the Higgs boson. The complementarity of the various analyses increases the sensitivity to new physics, and the resulting constraints are stronger than those from any individual analysis considered. The data exclude a heavy vector-boson triplet with mass below 5.8TeV in a weakly coupled scenario, below 4.4TeV in a strongly coupled scenario, and up to 1.5TeV in the case of production via vector-boson fusion.
