Measurements of top properties and mass in ATLAS / Bartos, Pavol (Comenius University (SK)) /ATLAS Collaboration
The top-quark mass is one of the key fundamental parameters of the Standard Model that must be determined experimentally. Its value has an important effect on many precision measurements and tests of the Standard Model. [...]

Measurement of the top quark Yukawa coupling from $t\bar{t}$ differential cross-section / Sinha, Supriya (Deutsches Elektronen-Synchrotron (DE)) /ATLAS Collaboration
The top-quark Yukawa coupling is extracted from the distribution of the top-quark pair ($t \bar{t}$) invariant mass in proton-proton collisions using $140\,\mathrm{fb}^{-1}$ of data at $\sqrt{s} = 13$ TeV collected in 2015-2018 by the ATLAS experiment at the Large Hadron Collider. In the region near the production threshold, the $t \overline{t}$ invariant mass spectrum is sensitive to electroweak virtual corrections, including contributions from Higgs boson exchange, thereby providing sensitivity to the top-quark Yukawa coupling. [...]

Latest results on ttbar production threshold in ATLAS / Majersky, Oliver (Deutsches Elektronen-Synchrotron (DE)) /ATLAS Collaboration
The exceptionally large dataset collected by the ATLAS detector at the highest proton-proton collision energies provided by the LHC enables precision testing of theoretical predictions using an extensive sample of top quark events. This wealth of data has also opened the door to new measurements including those particularly sensitive to the ttbar threshold region, such as measurement of enhancement of ttbar production due to non-relaticistic QCD effects in the threshold, and measurement of top-quark Yukawa coupling in the ttbar production.

Measurement of the top-quark Yukawa coupling from $t\overline{t}$ production in the lepton+jets final state using $pp$ collisions at $\sqrt{s} = 13$ TeV with the ATLAS detector / ATLAS Collaboration
The top-quark Yukawa coupling is extracted from the distribution of the top-quark pair ($t\overline{t}$) invariant mass in proton-proton collisions using 140 ${fb}^{-1}$ of data at $\sqrt{s} = 13$ TeV collected in 2015-2018 by the ATLAS experiment at the Large Hadron Collider. In the region near the production threshold, the $t\overline{t}$ invariant mass spectrum is sensitive to electroweak virtual corrections, including contributions from Higgs boson exchange, thereby providing sensitivity to the top-quark Yukawa coupling.

Measurements of Higgs boson coupling properties to bottom and charm quarks and 
$\tau$ leptons with the ATLAS detector / Moser, Brian (University of Freiburg (DE)) /ATLAS Collaboration
Probing the Yukawa couplings between the Higgs boson and fermions is essential to understanding the origin of fermion masses. Higgs boson decays into pairs of quarks or tau leptons offer a direct window into these couplings and broader Higgs boson properties. [...]

Evidence for the dimuon decay of the Higgs boson in $p\!p$ collisions with the ATLAS detector / ATLAS Collaboration
A search for the dimuon decay of the Higgs boson is presented based on $pp$ collision data recorded by ATLAS during Run 3 of the Large Hadron Collider, corresponding to an integrated luminosity of $165~\mathrm{fb}^{-1}$ at $\sqrt{s} = 13.6~\,\text{TeV}$. To enhance the sensitivity, the results are combined with those from Run 2 [...]

Measurements of Higgs boson coupling properties to bottom quarks and charm quarks with the ATLAS detector
 / Di Bello, Francesco Armando (INFN e Universita Genova (IT)) /ATLAS Collaboration
Testing the Yukawa couplings of the Higgs boson with fermions is essential to understanding the origin of fermion masses. Higgs boson decays to quark pairs are an important probe of these couplings, and of properties of the Higgs boson more generally. [...]

Fake-Rate determination for the ttH coupling measurement with a signature of two same electric charge light leptons associated with a tau using the ATLAS detector at the LHC / Mondal, Santu (Czech Technical University in Prague (CZ)) /ATLAS Collaboration
After the discovery of a Higgs boson, the measurements of its properties are at the forefront of research. The determination of the associated production of a Higgs boson and a pair of top quarks is of particular importance as the ttH Yukawa coupling is large and can probe for physics beyond the Standard Model.

Measurement of the associated production of a top-antitop-quark pair and a Higgs boson decaying into a $b\bar{b}$ pair in pp collisions at $\sqrt{s}=13$ TeV using the ATLAS detector at the LHC / ATLAS Collaboration
This paper reports the measurement of Higgs boson production in association with a $t\bar{t}$ pair in the $H\rightarrow b\bar{b}$ decay channel. The analysis uses 140 fb$^{-1}$ of 13 TeV proton-proton collision data collected with the ATLAS detector at the Large Hadron Collider. [...]

Property measurements of the Higgs boson production in association with top quark at the ATLAS detector / Poveda Torres, Ximo (Univ. of Valencia and CSIC (ES)) /ATLAS Collaboration
The study of Higgs boson production in association with one or two top quarks provides a key window into the properties of the two heaviest fundamental particles in the Standard Model, and in particular into their couplings. This talk presents property measurement of Higgs boson, in particular cross section and CP nature, with tH and ttH production in pp collisions collected at 13 TeV with the ATLAS detector using the full Run 2 dataset of the LHC..
