| Outline of Final Research Achievements |
Whether the Higgs boson, discovered in 2012 at CERN/LHC, generates the masses to all particles as predicted by the Standard Model? We measured the Higgs Yukawa couplings using the 25/fb of data collected by LHC/ATLAS experiment to shed light on this question.
Paris of the heaviest lepton, tau, are found to be produced via Higgs at a rate μ=1.43+0.43-0.37 normalized by the Standard Model. This corresponds to a significance of 4.5σ and proves for the first time the existence of the Yukawa coupling for the lepton. For the quark, the search covered the production of b-quark pairs via Higgs. The significance was 1.4σ for this mode, and we require more statistics to answer to the question.
