dc.description.abstract A measurement of the ZZ production cross section in the ℓ+ℓ′ℓ′+ and ℓ+νν¯ channels (ℓ = e, μ) in proton-proton collisions at √s = 8 TeV at the Large Hadron Collider at CERN, using data corresponding to an integrated luminosity of 20.3 fb-1 collected by the ATLAS experiment in 2012 is presented. The fiducial cross sections for ZZ → ℓ+ℓ′ℓ′+ and ZZ→ ℓ+νν¯ 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)-0.2-0.1 (lumi) pb, which is consistent with the Standard Model prediction of 6. 6+0.7-0.6 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. en
