Search for heavy resonances decaying into a vector boson and a Higgs boson in hadronic final states with 2016 data

A search for heavy resonances with a mass above $1~\mathrm{TeV}$, decaying to a vector boson and a Higgs boson is presented. The search considers hadronic decays of the vector boson, and Higgs boson decays to b quarks. The collimated pair of quarks are reconstructed as a single massive jet. The analysis is performed using a data sample collected in 2016 by the CMS experiment at the LHC in proton-proton collisions at a center-of-mass energy of $13~\mathrm{TeV}$, corresponding to an integrated luminosity of $35.9~\mathrm{fb}^{-1}$. The data is found to be consistent with the background expectation and used to place limits in the context of a theoretical model with a heavy vector triplet. In the benchmark scenario model B, a resonance with mass up to $3.4~\mathrm{TeV}$ is excluded at $95\%$ confidence level, and stringent limits are set on the parameters of the model.
