Higgs Precision Measurements with ATLAS

After the discovery of the Higgs boson, precise measurements of its properties are of particular importance to understand the true nature of the found particle, which could be the Standard Model predicted Higgs, or indeed offering to be a portal for new physics beyond the Standard Model. In this talk measurement of the mass, cross sections and the couplings of the Higgs boson in bosonic and fermionic decay channels with the ATLAS detector will be presented and compared with Standard Model predictions.
