Search for Standard Model Higgs boson in the two-photon final state in ATLAS

Abstract

We report on the search for the Standard Model Higgs boson decaying into two photons based on proton-proton collision data with a center-of-mass energy of 7 TeV recorded by the ATLAS experiment at the LHC. The dataset has an integrated luminosity of about 1.08 fb-1. The expected cross section exclusion at 95% confidence level varies between 2.0 and 5.8 times the Standard Model cross section over the diphoton mass range 110 - 150 GeV. The maximum deviations from the background-only expectation are consistent with statistical fluctuations.
