Extracting top-Yukawa coupling from tt cross-section using ATLAS data — •Supriya Sinha — DESY, Hamburg and Zeuthen, Germany

This work aims to extract the top-Yukawa coupling (Y_t) from tt cross section close to the threshold. In order to achieve this, one can use the kinematic distributions in tt production along with the virtual Higgs boson loop correction. This boson exchange modifies the differential distributions near tt production threshold energy. It becomes highly sensitive to Y_t, and hence, is used to extract its value.

This talk introduces the involved physics processes and gives an insight to the analysis strategy. The decay channel considered for the analysis is the lepton+jets final state. Full Run-II data with the integral luminosity of 139 fb⁻¹ taken from the ATLAS experiment at 13 TeV, is used.
