Results on SM Higgs boson searches at high mass at the LHC (ATLAS + CMS)

We present results from searches for the standard model Higgs boson with a mass greater than 200 GeV in pp collisions at $\sqrt{s} = $ 7 TeV. The data are collected at the LHC with both ATLAS and CMS detectors, and correspond to integrated luminosity of ~ 5\ \ifb each. Searches are performed in...

Sumario:We present results from searches for the standard model Higgs boson with a mass greater than 200 GeV in pp collisions at $\sqrt{s} = $ 7 TeV. The data are collected at the LHC with both ATLAS and CMS detectors, and correspond to integrated luminosity of ~ 5\ \ifb each. Searches are performed in the two main decay modes $WW$ and $ZZ$. No significant excess of events above the standard model background expectations is observed, and upper limits on the Higgs boson production relative to the standard model Higgs expectation are derived. A standard model Higgs boson is excluded in the mass range up to 539 GeV or 600 GeV at 95\% confidence level by the ATLAS or CMS experiments respectively.
