Abstract
A search for a heavy Standard Model Higgs boson decaying via H → Z Z →ℓ+ℓ-qq, where ℓ= e or μ, is presented. The search uses a data set of pp collisions at √ s = 7 TeV, corresponding to an integrated luminosity of 4.7 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 GeV are derived. A Standard Model Higgs boson with a mass in the range 300 GeV ≤ mH ≤ 322 GeV or 353 GeV ≤ mH ≤ 410 GeV is excluded at 95% CL. The corresponding expected exclusion range is 351 GeV ≤ mH ≤ 404 GeV at 95% CL
