  "description": "<p>A 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 4.5\u00a0fb\u22121 of proton\u2013proton collisions at a center-of-mass energy of 7 TeV and 20.3\u00a0fb\u22121 at 8 TeV 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\u00afH production cross section. The observed exclusion upper limit at 95% confidence level is 6.7 times 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 tt\u00afH and tH cross sections as well as the H\u2192\u03b3\u03b3 branching fraction on the Yukawa coupling. Lower and upper limits at 95% confidence level are set at \u22121.3 and +8.0 times the Yukawa coupling strength in the Standard Model.</p>",
