摘要：
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 -> 2L2 nu 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 4.0 sigma. In the latter channel, the boson is observed with a local significance of 6.7 sigma, with the mass 125.8 +/- 0.5 (stat.) +/- 0.2 (syst.) GeV. In both channels the observed signal strength mu = sigma/sigma(SM), relative to the expectation for the standard model Higgs boson, is consistent with one.
