Search for heavy resonances decaying into a vector boson and a Higgs boson in the (ℓℓ,ℓ,)b final state

A search for heavy resonances in final states with a Higgs boson and a vector boson is presented, performed in the data collected with the CMS detector at √s = 13 TeV during 2015. The vector boson can be either a Z or W boson decaying leptonically (electrons, muons or neutrinos), whereas the Higgs boson decays hadronically into a couple of b-quarks of high momentum, detected as a single massive jet. The investigated final states consist of two b-quarks and zero, one or two charged leptons. Background shape and normalization are derived through a hybrid data-Monte Carlo method. The search is performed by examining the distribution of the reconstructed mass for a localized excess. Upper limits are derived as a function of the resonance mass and natural width, and are interpreted within the Heavy Vector Triplet theoretical model, as predicted in many scenarios beyond the standard model.
