| Abstract: A search for a standard-model-like Higgs boson decaying into two Z bosons with subsequentdecay into two leptons and two quarks, $\mathrm{H\to ZZ\to \ell^+\ell^- q\bar{q}}$ is performed. The analysis uses 19.7 fb$^{-1}$ of data collected by the CMS experiment from proton-proton collisions produced in LHC at $\sqrt{s} =$ 8 TeV. The search exploits the kinematic information and the flavor tagging of the leading particles of the event in order to isolate hypothetical Higgs boson-like signals in the 230 GeV to 1000 GeV mass range. At high mass the two quarks from the Z-decay merge into a single jet and are analyzed with jet-substructure methods. The sensitivity of the analysis is further improved compared to previous similar searches by a dedicated study of a Vector Boson Fusion signatures. We interpret the data in terms of a standard-model-like Higgs boson as well as an electroweak singlet visible through the interference with the recently discovered 125 GeV boson. No evidence of a signal is found and upper limits are set on the production cross section. | ||
