Description
The inclusive top quark pair ($t\bar{t}$) production cross-section $\sigma_{t\bar{t}}$ has been measured in proton–proton collisions at $\sqrt{s} = 13.6$~TeV, using 11.3 fb${}^{-1}$ of data collected in 2022 by the ATLAS experiment at the Large Hadron Collider.
Additionally, a measurement of the ratio of the $t\bar{t}$ and the $Z$ boson production cross-section in a $Z$ fiducial phase space matching the detector-level selection decaying into a single lepton flavour is reported.
