Jets, W/Z and Top Quark Production at the LHC and Status of the Higgs Boson Searches at ATLAS.

Oliver Kortner
Until the end of 2011 the ATLAS and CMS experiments have each analysed up to 5~fb$^{-1}$ of $pp$ collision data at $\sqrt{s}=7$~TeV. Their studies show excellent agreement between Standard Model predictions and experimental measurements for the production of jets, $W/Z$ bosons, and top quarks. The ATLAS experiment has been able to exclude a Standard Model Higgs boson at 95\% confidence level in the mass intervals $\unit{110}{\GeV} < m_H < \unit{117.5}{\GeV}$, $\unit{118.5}{\GeV} < m_H < \unit{122.5}{\GeV}$,...
