    Abstract:
    A combined search for the Standard Model Higgs boson with the ATLAS experiment at the LHC using datasets corresponding to integrated luminosities from 1.04 fb<sup>-1</sup> to 4.9 fb<sup>-1</sup> of pp collisions collected at s=7TeV is presented. The Higgs boson mass ranges 112.9-115.5 GeV, 131-238 GeV and 251-466 GeV are excluded at the 95% confidence level (CL), while the range 124-519 GeV is expected to be excluded in the absence of a signal. An excess of events is observed around m<inf>H</inf>~126GeV with a local significance of 3.5 standard deviations (σ). The local significances of H→γγ, H→ZZ<sup>(z.ast;)</sup>→ℓ<sup>+</sup>ℓ<sup>-</sup>ℓ<sup>'+</sup>ℓ<sup>'-</sup> and H→WW(z.ast;)→ℓ+νℓ'-ν- the three most sensitive channels in this mass range, are 2.8σ, 2.1σ and 1.4σ, respectively. The global probability for the background to produce such a fluctuation anywhere in the explored Higgs boson mass range 110-600 GeV is estimated to be ~1.4% or, equivalently, 2.2σ. © 2012 CERN.
