Resumen:
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 fb-1 collected with the ATLAS detector at the Large Hadron Collider in proton-proton collisions at a center-of-mass energy of √s=7
TeV. In the diphoton mass range 110150 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 110150 GeV, this
significance becomes 1.5 standard deviations. The standard model Higgs
boson is excluded at 95% confidence level in the mass ranges of
113115 GeV and 134.5136 GeV.
