摘要：

Among all the elementary particles in the Standard Model (SM), the Higgs boson has a unique and fundamental role related to the electroweak symmetry breaking and the generation of particle masses. The experimental measurement of Higgs boson couplings serves as a test bench for the SM as well as a potential portal to new physics. In this talk, I will present the latest combined measurements of the Higgs boson couplings, and also the first direct study of top Yukawa coupling CP properties using ttH and tH productions from the ATLAS experiment.  These results, based on the large LHC Run 2 dataset, are sensitive to potential Beyond the SM physics and represent the state of the art from the LHC.
