A search for a high mass standard-model-like Higgs boson decaying into two Z bosons with subsequent decay into two leptons and two quarks performed at CMS is presented. The analysis is based on 19.7 1/fb of proton-proton collisions produced in LHC at center-of-mass energy of 8 TeV. Different categories are exploited in order to isolate hypothetical Higgs boson-like signals in the mass range up to 1 TeV. The data are interpreted in terms of a standard-model-like Higgs boson as well as an electroweak singlet, visible through the interference with the 125 GeV Higgs boson. No evidence of a signal is found and upper limits are set on the production cross section and other model parameters.
