Abstract

A search for heavy resonances decaying into a W or Z boson and a Higgs boson produced in protonproton collisions at the Large Hadron Collider at s=13TeV is presented. The analysis utilizes the dominant Wqq¯ or Zqq¯ and Hbb¯ decays with substructure techniques applied to large-radius jets. A sample corresponding to an integrated luminosity of 139fb1 collected with the ATLAS detector is analyzed and no significant excess of data is observed over the background prediction. The results are interpreted in the context of the heavy vector triplet model with spin-1 W and Z bosons. Upper limits on the cross section are set for resonances with mass between 1.5 and 5.0 TeV, ranging from 6.8 to 0.53 fb for WWH and from 8.7 to 0.53 fb for ZZH at the 95% confidence level.
