Latest Studies of the SM Higgs Boson Couplings to Fermions at ATLAS

This talk will present the latest studies on the Yukawa couplings of the SM Higgs boson with 139 fb$^{-1}$ data collected using the ATLAS detector at a center-of-mass energy of 13 TeV. A first direct probe of CP violation in the top-quark Yukawa coupling using events where the Higgs boson is produced in association with two top quarks, and decays into two photons will be discussed. The latest result on the Higgs-boson production in association with a W or Z boson in the H → bb channel will be presented as well. Finally, the search for Higgs boson decays into two muons or two electrons will be presented.
