Abstract
Since its discovery in July 2012, it has become mandatory to study the couplings of the Higgs boson with other Standard Model particles. The associated production of Higgs and top-antitop pairs (t¯tH) gives direct access to the Higgs-top couplings. Due to the different decay modes of the t¯t pairs and of the Higgs boson, the process displays a large variety of decay channels involving in the final state, b¯b pairs, γγ and multileptonic (including τ ) states. Although the sensitivity is still limited by the Run I statistics, the assessment of the analysis methods will be essential for constraining the t-H coupling using the data collected from 2015 at ATLAS at LHC. These include background estimation, selection optimization and systematics control.
