Combined search for the Standard Model Higgs boson using up to 4.9 fb-1
of pp collision data at sqrt(s) = 7 TeV with the ATLAS detector at the LHC    [PDF]

ATLAS Collaboration

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-1 to 4.9 fb-1 of pp collisions collected at sqrt(s) = 7 TeV 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 mH ~ 126 GeV with a local significance of 3.5 standard
deviations (sigma). The local significance of H -> gamma gamma, H -> ZZ(*) ->
lll'l' and H -> WW(*) -> lvl'v, the three most sensitive channels in this mass
range, are 2.8 sigma, 2.1 sigma and 1.4 sigma, 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 2.2 sigma.
