A measurement of the ZZ production cross section in the l-l+l'-l' + and l-l+?v¯ channels (l = e, µ) in proton-proton collisions at sv=8s=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'-l' + and ZZ?l-l+??¯ 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.
