Search for the Standard Model Higgs boson with the ATLAS detector

The experimental results of the search for the Standard Model Higgs boson with the ATLAS detector at the Large Hadron Collider are reported. They are based on pp collision data collected in 2011 and 2012 with an integrated luminosity of up to 4.9 $fb^{-1}$ at $sqrt{s} = 7 $TeV and up to 5.9 $fb^{-1}$ at $sqrt{s} = 8 $TeV, respectively. The search combines several Higgs boson decay channels in a wide range of Higgs boson masses from 110 GeV to 600 GeV. A Standard Model Higgs boson is excluded at the 95$%$ confidence level in the mass ranges from 110.0 to 122.6 GeV and from 129.7 to 558 GeV, while the range from 110 to 582 GeV is expected to be excluded in the absence of a signal. An excess of events is observed around 126.5 GeV with a local significance of 5.0 $sigma$.
