The ATLAS and CMS experiments at the LHC have discovered the Higgs boson predicted by the Standard Model (SM). This discovery completes the SM, making the theory self-consistent up to the Planck Energy Scale. Yet we also know that the SM is not a full theory because it cannot explain the observed amount of baryonic and dark matter and because it does not include gravity. The SM could be the low energy manifestation of a more fundamental theory at a higher energy scale. In the SM Lagrangian, the Higgs boson mass term is sensitive to the energy scale at which new physics enters - this effect motivates many models of new physics. This presentation will review some of the recent ATLAS measurements of the Higgs boson properties and will discuss LHC potential to reveal new physics through future measurements in the Higgs boson sector.
