Description
The study of Higgs boson production in association with one or two top quarks offers a unique opportunity to probe the interactions between the two heaviest particles in the Standard Model. This talk presents measurements of key Higgs boson properties - specifically the production cross section and CP nature - in events produced via tH and ttH processes. The results are based on the full Run 2 dataset of proton-proton collisions at \sqrt{s} = 13 TeV, recorded by the ATLAS detector at the LHC.
