Observation of an enhancement near the top-antitop quark threshold by ATLAS / Behr, Janna Katharina (Deutsches Elektronen-Synchrotron (DE)) /ATLAS Collaboration
In this talk, a measurement of $t\bar{t}$ production in the invariant-mass region near the pair production threshold is presented. The measurement is conducted in final states with two charged leptons and multiple jets and is based on 140 fb$^{−1}$ of proton–proton collision data collected at $\sqrt{s} = 13$ TeV with the ATLAS detector. [...]

WbWb Cross Section in the Semi-leptonic Channel / Novak, Tadej (Jozef Stefan Institute (SI)) /ATLAS Collaboration
This presentation covers differential cross-section measurements of events consistent with the $W^{+}W^{-}b\bar{b}$ final state. The analysis is based on 140 fb$^{-1}$ of proton-proton collision data at $\sqrt{s}$ = 13 TeV recorded with the ATLAS detector during Run 2 of the Large Hadron Collider (2015-2018). [...]

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. [...]

ttWj EW and tt asymmetry EFT results / Kim, Dongwon (University of California Berkeley (US)) /ATLAS Collaboration
This presentation reports two recent ATLAS results interpreted in the framework of the Standard Model Effective Field Theory (SMEFT). The first is the search for electroweak production of t\bar{t}Wj This analysis provides the ATLAS constraints on the SMEFT operators \mathcal{O}{Ht} and \mathcal{O}{HQ}^{(1)}, which are among the least constrained in the top sector, and demonstrates how the inclusion of t\bar{t}Wj_{\mathrm{EW}} information helps resolve parameter degeneracies that remain when interpreting t\bar{t}Z data alone.

Recent results on measurements of the Higgs boson in ATLAS / Bullard, Brendon (SLAC National Accelerator Laboratory (US)) /ATLAS Collaboration
The event rates and kinematics of Higgs boson production and decay processes at the LHC are sensitive probes of possible new phenomena beyond the Standard Model (BSM). This talk presents the most recent results in the measurements of Higgs boson production and decay rates, obtained using the full Run 2 and partial Run 3 pp collision dataset collected by the ATLAS experiment at 13 TeV and 13.6 TeV.

Search for Higgs boson decays into a pair of pseudoscalar particles in the $\gamma\gamma\tau\tau$ final state using $pp$ collisions at $\sqrt{s} = 13$ TeV with the ATLAS detector / Aikot, Arya (Univ. of Valencia and CSIC (ES)) /ATLAS Collaboration
Many well-motivated extensions of the Standard Model predict light (pseudo)scalars, referred to as 𝑎 bosons, that couple to the 125 GeV Higgs boson, enabling new exotic decay modes. This study presents a search for Higgs boson decays into a pair of such particles, $H\rightarrow bb$, where one 𝑎-boson decays into a photon pair and the other into a $\tau$-lepton pair, performed for the first time at the Large Hadron Collider.

Precision measurements of Drell-Yan processes in ATLAS / Lewis, Daniel (Centre National de la Recherche Scientifique (FR)) /ATLAS Collaboration
Precision measurements of Drell-Yan processes (both on-shell and off-shell W and Z bosons) offer key input to improve on the understanding of QCD and the accuracy of PDFs. In addition, these measurements are deeply linked with the achievements in electroweak parameter precision tests (such as W boson mass measurement). [...]
