Physics Letters B, 138764.03702693http://dx.doi.org/10.1016/j.physletb.2024.138764https://hdl.handle.net/20.500.12713/6863This paper reports cross-section measurements of ZZ production in pp collisions at s=13.6TeV 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→4ℓ (ℓ=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 <mZ< 116 GeV for both Z bosons, yielding 16.8±1.1 pb. The results are well described by the Standard Model predictions. © 2024 The Author(s)eninfo:eu-repo/semantics/openAccessArticle855WOS:0012876036000012-s2.0-85195462869Q110.1016/j.physletb.2024.138764Q1
