_aSearch for H→γγ produced in association with top quarks and constraints on the Yukawa coupling between the top quark and the Higgs boson using data taken at 7 TeV and 8 TeV with the ATLAS detector _cG. Aad, B. Abbott, J. Abdallah [et.al.] |

| 520 | 3 | _aA search is performed for Higgs bosons produced in association with top quarks using the diphoton decay mode of the Higgs boson. Selection requirements are optimized separately for leptonic and fully hadronic final states from the top quark decays. The dataset used corresponds to an integrated luminosity of 4.5fb−1of proton–proton collisions at a center-of-mass energy of 7TeV and 20.3fb−1at 8TeV recorded by the ATLAS detector at the CERN Large Hadron Collider. No significant excess over the background prediction is observed and upper limits are set on the tt H production cross section. The observed exclusion upper limit at 95% confidence level is 6.7times the predicted Standard Model cross section value. In addition, limits are set on the strength of the Yukawa coupling between the top quark and the Higgs boson, taking into account the dependence of the ttHand tHcross sections as well as the H→γγbranching fraction on the Yukawa coupling. Lower and upper limits at 95% confidence level are set at −1.3and +8.0times the Yukawa coupling strength in the Standard Model. | |
