Measurement of the Higgs boson couplings and their interpretations in fermionic final states at the ATLAS experiment

Thanks to the statistics of pp collision collected by the ATLAS experiment a 13 TeV a the LHC Run 2, detailed measurements of Higgs boson properties and its interactions can be performed using its decays into fermions, shining light over the properties of the Yukawa interactions. This talk presents the latest measurements of the Higgs boson properties by the ATLAS experiment in various fermionic decay channels, including Higgs production in association with top quarks, Simplified Template Cross Sections, and their interpretations. Specific scenarios of physics beyond the Standard Model are tested, as well as a generic extension in the framework of the Standard Model Effective Field Theory.
