Description

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 has been performed at CMS based on 19.7 fb$^{−1}$ of proton-proton collisions produced in LHC at $\sqrt{s}$=8 TeV. The search uses different channels in order to isolate hypothetical Higgs boson-like signals in the mass range up to 1 TeV. The data is interpreted 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 times branching ratio cross section.
