Resumo: A search for a heavy Standard Model Higgs boson decaying via View the MathML sourceH→ZZ→ℓ+ℓ−qq¯, where ℓ=eℓ=e or μ, is presented. The search uses a data set of pp collisions at View the MathML sources=7 TeV, corresponding to an integrated luminosity of 4.7 fb−14.7 fb−1 collected in 2011 by the ATLAS detector at the CERN LHC. No significant excess of events above the estimated background is found. Upper limits at 95% confidence level on the production cross section of a Higgs boson with a mass in the range between 200 and 600 GeV600 GeV are derived. A Standard Model Higgs boson with a mass in the range 300 GeV⩽mH⩽322 GeV300 GeV⩽mH⩽322 GeV or 353 GeV⩽mH⩽410 GeV353 GeV⩽mH⩽410 GeV is excluded at 95% CL. The corresponding expected exclusion range is 351 GeV⩽mH⩽404 GeV351 GeV⩽mH⩽404 GeV at 95% CL.
