This thesis reports the discovery of the new boson recently observed at a mass near 125 GeV in the CMS experiment at CERN. The measurements of the properties of the new boson are reviewed. The results are obtained from a comprehensive search for the standard model Higgs boson in the H → ZZ decay channel, where both Z bosons decay to electron or muon lepton pairs. The search covers Higgs boson mass hypotheses in the range 110 < mH < 1000 GeV. The analysis uses proton-proton collision data recorded by the CMS detector at the LHC, corresponding to integrated luminosities of 5.1 fb^−1 at sqrt(s) = 7 TeV and 12.2 fb^−1 at sqrt(s) = 8 TeV. The new boson is observed with a local significance above the expected background of 4.5 standard deviations...
