Investigation of the Higgs Yukawa Couplings to Charm and Bottom Quarks Using the ATLAS Detector

The Higgs mechanism is a cornerstone of the Standard Model, explaining the origin of particle masses. The existence of the Higgs boson was firmly established by its discovery in 2012 at the LHC, and an extensive program remains underway to precisely measure its properties. The Higgs interaction rates with quarks are vital observables to test the validity of the Standard Model and to explore the landscape of possible new physics, but their measurement remains experimentally challenging. This talk will present recent ATLAS results constituting some of the world's most precise characterization of the Higgs couplings to bottom and charm quarks, obtained with a re-analysis of the 2015-2018 ATLAS dataset.
