Top physics in ATLAS and CMS / Burgard, Carsten (Hamburg U.) /ATLAS and CMS Collaborations
Top-quark physics at the Large Hadron Collider has entered a precision era, enabled by the full Run 2 data set and the first results from Run 3. The large production cross section of top quarks allows for a diverse experimental program ranging from precision measurements of Standard Model parameters to searches for rare processes and indirect probes of physics beyond the Standard Model. [...]

Precise measurement of the $t\bar{t}$ production cross-section and lepton differential distributions in $e\mu$ dilepton events / Hirschbuehl, Dominic (Wuppertal U.)
Measurements of the inclusive and differential top-quark pair ($t\bar{t}$) cross-sections in proton–proton collisions at $\sqrt{s} = 13\,\mathrm{TeV}$, using $140\,\mathrm{fb}^{-1}$ of data collected by the ATLAS experiment at the Large Hadron Collider, are presented. [...]

Observation of a cross-section enhancement near the $t\bar{t}$ production threshold in $\sqrt{s}=13$ TeV $pp$ collisions with the ATLAS detector / ATLAS Collaboration
A measurement of $t\bar{t}$ production is presented in the invariant-mass region near the pair production threshold, $m_{t\bar{t}} \sim 345$ GeV, in final states with two charged leptons and multiple jets. [...]
