Abstract

A search for the standard model Higgs boson is performed in the diphoton decay channel. The data used
correspond to an integrated luminosity of 4:9 fb1 collected with the ATLAS detector at the Large Hadron
Collider in proton-proton collisions at a center-of-mass energy of 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 GeVand 134.5–136 GeV.
