Search for heavy resonances decaying into a W or Z boson and a Higgs boson in final states with leptons and b-jets in 36 fb<sup>−1</sup> of √s = 13 TeV pp collisions with the ATLAS detector

A search is conducted for new resonances decaying into a W or Z boson and a 125 GeV Higgs boson in the ν¯νb¯b, ℓ±νb¯b, and ℓ+ℓ−b¯b final states, where ℓ± = e± or μ±, in pp collisions at √s = 13 TeV. The data used correspond to a total integrated luminosity of 36.1 fb<sup>−1</sup> collec...

description A search is conducted for new resonances decaying into a W or Z boson and a 125 GeV Higgs boson in the ν¯νb¯b, ℓ±νb¯b, and ℓ+ℓ−b¯b final states, where ℓ± = e± or μ±, in pp collisions at √s = 13 TeV. The data used correspond to a total integrated luminosity of 36.1 fb<sup>−1</sup> collected with the ATLAS detector at the Large Hadron Collider during the 2015 and 2016 data-taking periods. The search is conducted by examining the reconstructed invariant or transverse mass distributions of Wh and Zh candidates for evidence of a localised excess in the mass range of 220 GeV up to 5 TeV. No significant excess is observed and the results are interpreted in terms of constraints on the production cross-section times branching fraction of heavy W' and Z' resonances in heavy-vectortriplet models and the CP-odd scalar boson A in two-Higgs-doublet models. Upper limits are placed at the 95% confidence level and range between 9.0 × 10<sup>−4</sup> pb and 7.3 × 10<sup>−1</sup> pb depending on the model and mass of the resonance.
