Abstract:

Immediately following the discovery of a new boson in July 2012, a rapid series of measurements confirmed that its couplings and spin conform to the prediction for the Standard Model Higgs boson. Starting from February of this year, ATLAS initiated studies of the differential cross sections of the Higgs boson, in the diphoton decay channel. These measurements cast a larger net in the search for discrepancies with respect to the SM, and signal the beginning of a new era of precision Higgs physics underpinned by a dialog with the theory community. Yet -- as the results again show good agreement with the SM -- I will make a final step, to motivate and describe current work on a search for BSM dihiggs production.
