    • Higgs boson searches in the H>WW(∗)→ℓνℓν (ℓ = e,μ) and the H→WW(∗)→ℓvqq decay modes, using 1.04 fb-1 of proton-proton collision data delivered by the large hadron collider (LHC) at a centre-of-mass energy of 7 TeV collected with the ATLAS detector, are presented. An upper bound is placed on the Higgs boson production cross-section as a function of mH. The H→WW(∗)→ℓνℓν analysis excludes a Higgs boson with a mass in the range from 158 GeV to 186 GeV at 95% confidence level, while the expected Higgs boson mass exclusion range is 142 ≤ mH ≤ 186 GeV. An excess of events in data corresponding to more than 2σ significance is observed for the Higgs boson mass range from 126 GeV to 158 GeV The H→WW(∗)→ℓνqq analysis place limits on the Higgs boson cross section that are between 1.4 to 20 times the expected standard model cross section in the mass range from 240 GeV to 600 GeV.
