A search for the Standard Model Higgs boson in the two photon decay channel is reported, using1.08 fb−1 of proton–proton collision data at a centre-of-mass energy of 7 TeV recorded by the ATLASdetector. No significant excess is observed in the investigated mass range of 110–150 GeV. Upper limitson the cross-section times branching ratio of between 2.0 and 5.8 times the Standard Model predictionare derived for this mass range.
