Search for a Standard Model Higgs boson in the mass range 200–600 GeV in the <i>H → Z Z → ℓ+ℓ−q ̄q</i> decay channel with the ATLAS detector
A search for a heavy Standard Model Higgs boson decaying via <i>H → Z Z → ℓ+ℓ−q ̄q</i>, 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<sup>−1</sup> collected in 2011 by the ATLAS d...

description |
A search for a heavy Standard Model Higgs boson decaying via <i>H → Z Z → ℓ+ℓ−q ̄q</i>, 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<sup>−1</sup> 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 ≼ m<sub>H</sub> ≼ 322 GeV or 353 GeV ≼ m<sub>H</sub> ≼ 410 GeV is excluded at 95% CL. The corresponding expected exclusion range is 351 GeV ≼ m<sub>H</sub> ≼ 404 GeV at 95% CL. |
