Measurement of the $t\bar{t}$ cross section and its ratio to the $Z$ production cross section using $pp$ collisions at $\sqrt{s}=13.6$ TeV with the ATLAS detector

ATLAS Collaboration

The inclusive top-quark-pair production cross section ${\sigma }_{t\bar{t}}$ and its ratio to the $Z$-boson production cross section have been measured in proton--proton collisions at $\sq…
