Query: Search for the Standard Model Higgs boson in the diphoton decay channel
  with 4.9 fb-1 of pp collisions at sqrt(s) = 7 TeV with ATLAS   A search for the Standard Model Higgs boson is performed in the diphoton
decay channel. The data used corresponds to an integrated luminosity of 4.9
fb-1 collected with the ATLAS detector at the Large Hadron Collider in
proton-proton collisions at a center-of-mass energy of sqrt(s) = 7 TeV. In the
diphoton mass range 110-150 GeV, the largest excess with respect to the
background-only hypothesis is observed at 126.5 GeV, with a local significance
of 2.8 standard deviations. Taking the look-elsewhere effect into account in
the range 110-150 GeV, this significance becomes 1.5 standard deviations. The
Standard Model Higgs boson is excluded at 95% confidence level in the mass
ranges of 113-115 GeV and 134.5-136 GeV.
