Combination of searches for heavy spin-1 resonances using 139 fb−1 of proton-proton collision data at √ s = 13 TeV with the ATLAS detector Aad, G. Pérez-Victoria Moreno De Barreda, Manuel María Atlas Collaboration, / Beyond Standard Model Exotics Hadron-Hadron Scattering A combination of searches for new heavy spin-1 resonances decaying into different pairings 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 √ s = 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. 2024-10-09T12:25:54Z 2024-10-09T12:25:54Z 2024-04-19 journal article Aad, G. & Pérez Victoria Moreno de Barreda, M.M. & Atlas Collaboration.
