Measurement of ZZ production cross-sections in the four-lepton final state in pp collisions at √s=13.6 TeV with the ATLAS experiment
| Resumo: | This paper reports cross-section measurements of \( ZZ \) production in \( pp \) collisions at \( \sqrt{s} = 13.6 \) TeV at the Large Hadron Collider. The data were collected by the ATLAS detector in 2022, and correspond to an integrated luminosity of 29 fb\(^{-1}\). Events in the \( ZZ \rightarrow 4\ell \) (\( \ell = e, \mu \)) final states are selected and used to measure the inclusive and differential cross-sections in a fiducial region defined close to the analysis selections. The inclusive cross-section is further extrapolated to the total phase space with a requirement of \( 66 < m_Z < 116 \) GeV for both \( Z \) bosons, yielding \( 16.8 \pm 1.1 \) pb. The results are well described by the Standard Model predictions. |
