Abstract
Searches for the standard model Higgs boson using approximatively 5 fb−1 of 7TeV and 19.6 fb−1 of 8TeV pp collisions data collected with the CMS detector at LHC in the fully leptonic channels H → WW → 2l2ν and H → ZZ → 4l have been performed. In the former channel, an excess of events is observed above background, consistent with the expectations from a Higgs boson of mass around 125 GeV with a statistical significance of 4.0σ. In the latter channel, the boson is observed with a local significance of 6.7σ, with the mass 125.8 ± 0.5 (stat.) ±0.2 (syst.) GeV. In both channels the observed signal strength μ = σ/σSM, relative to the expectation for the standard model Higgs boson, is consistent with one.
