The fiducial cross sections for ZZ → ℓ⁺ℓ⁻ℓ′⁻ℓ′⁺ and ZZ→ ℓ⁻ℓ⁺νν̅ are measured in selected phase-space regions. The total cross section for ZZ events produced with both Z bosons in the mass range 66 to 116 GeV is measured from the combination of the two channels to be 7.3 ± 0.4(stat) ± 0.3(syst) _{-0.1}^{-0.2} (lumi) pb, which is consistent with the Standard Model prediction of 6. 6_{−0.6}^{+ 0.7} pb. The differential cross sections in bins of various kinematic variables are presented. The differential event yield as a function of the transverse momentum of the leading Z boson is used to set limits on anomalous neutral triple gauge boson couplings in ZZ production.enCC BY 4.0 (Attribution)©2017 CERN, for the ATLAS Collaborationhttp://creativecommons.org/licenses/by/4.0/Hadrons--ScatteringZ bosonsProton-proton interactionsLuminescenceStandard model (Nuclear physics)articleAaboud, M., G.
