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.
