Measurement of Production Cross-sections in the Four-lepton Final State in Collisions at with the ATLAS experiment
Description
This paper reports cross-section measurements of ZZ production in pp collisions at $\sqrt{s}=13.6\phantom{\rule{0.25em}{0ex}}\text{TeV}$ 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\to 4\ell $ ($\ell =e$, μ) 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 $16.8±1.1$ pb. The results are well described by the Standard Model predictions.
