| dc.description | A measurement of the ZZ production cross section in the ℓ<sup>−</sup>ℓ<sup>+</sup>ℓ′<sup>−</sup>ℓ′<sup>+</sup> and ℓ<sup>−</sup>ℓ<sup>+</sup>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<sup>-1</sup> collected by the ATLAS experiment in 2012 is presented. The fiducial cross sections for ZZ → ℓ<sup>−</sup>ℓ<sup>+</sup>ℓ′<sup>−</sup>ℓ′<sup>+</sup> and ZZ→ ℓ<sup>−</sup>ℓ<sup>+</sup>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)<sup>-0.2</sup><sub>-0.1</sub> (lumi) pb, which is consistent with the Standard Model prediction of 6. 6<sup>+0.7</sup><sub>-0.6</sub> 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. | |
