In 2012, the ATLAS and CMS experiments at the Large Hadron Collider (LHC) at CERN announced the discovery of the Higgs boson, 48 years after it was first predicted by Peter Higgs, Francois Englert, Robert Brout and others. Subsequently further data from Run I of the LHC has confirmed many characteristics of the Standard Model Higgs boson, including its decays to the photon and W- and Z-bosons, and its spin-less nature. However there is less strong evidence for couplings between the Higgs boson and fermions. ATLAS has evidence for Higgs boson decay into tau-leptons, but no conclusive evidence for Higgs boson decay into quarks.
I will review the ATLAS measurements of the 125 GeV Higgs boson, and the prospects for ATLAS to discover the couplings between the Higgs boson and the fermions during Run II of the LHC, and share some of the excitement of the Edinburgh group from the award of the Nobel Prize in Physics 2013 to Peter Higgs and François Englert.
