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(-1) of root s=13 TeV pp collisions with the ATLAS detector uri icon

abstract

  • Abstract A search is conducted for new resonances decaying into a W or Z boson and a 125 GeV Higgs boson in the $$
    u overline{
    u}boverline{b} $$     b b     , $$ {ell}^{pm}
    u boverline{b} $$     b b     , and $$ {ell}^{+}{ell}^{-}boverline{b} $$ + b b final states, where = e or , in pp collisions at $$ sqrt{s}=13 $$ s = 13 TeV. The data used correspond to a total integrated luminosity of 36.1 fb1 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 W h 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-vector-triplet 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 9.0 104 pb and 7.3 101 pb depending on the model and mass of the resonance.
