About

Using the full Run-2 dataset at √s = 13 TeV, the ATLAS Collaboration has measured the 𝑡𝑡ˉ production cross-section with a precision of 1.3%, using opposite-sign electron-muon pairs and b-tagged jets. Several differential cross-section measurements are provided to test the QCD predictions at next-to-next-to-leading order precision as well as extract the top-quark pole mass. The Collaboration has also performed its first extraction of the top-quark Yukawa coupling from the 𝑡𝑡ˉ invariant-mass spectrum near threshold using the lepton+jets final state, including 𝑡𝑡ˉquasi bound-state effects.
