Higgs boson couplings to quarks at the ATLAS experiment

Testing the couplings of the Higgs boson to quarks is important to understand the origin of quark masses. The talk presents cross section measurements in Higgs boson decays to two $b$ quarks, as well as a search for Higgs boson decays to two $c$ quarks. It also presents measurements of Higgs boson production in association with a $t\bar{t}$ pair using Higgs boson decays to $b\bar{b}$ pairs, to two $Z$ bosons, to other multi-lepton final states, and to a pair of photons. All analyses are based on $pp$ collision data collected at 13 TeV.
