Abstract | A search for a massive resonance decaying into a standard model Higgs boson (H) and a W or Z boson is reported. The analysis is performed on a data sample corresponding to an integrated luminosity of 19.7~fb, collected in proton-proton collisions at a centre-of-mass energy of 8~TeV with the CMS detector at the LHC. Signal events in which the decay products of Higgs, W or Z bosons at high Lorentz boost are contained within a single reconstructed jet are identified using jet substructure techniques, including the tagging of b hadrons. This is the first search for heavy resonances decaying into HW or HZ resulting in an all-jets final state, as well as the first application of jet substructure techniques to identify decays at high Lorentz boost. No significant signal is observed and limits are set at the 95\% confidence level on the production cross section of W' and Z' in a model with mass-degenerate charged and neutral spin-1 resonances. Resonance masses are excluded for W' in [1.0, 1.6] TeV, for Z' in [1.0, 1.1], [1.3,1.5] TeV, and for mass-degenerate W' and Z' in [1.0, 1.7] TeV ranges. |
