Abstract
A search for heavy resonances decaying into a or boson and a Higgs boson produced in collisions at the Large Hadron Collider at is presented. The analysis utilizes the dominant or and decays with substructure techniques applied to large-radius jets. A sample corresponding to an integrated luminosity of 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 and 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 and from 8.7 to 0.53 fb for at the 95% confidence level.
