We present a new measurement of the production cross section σ(pp̄→ZZ) at a center-of-mass energy s√=1.96 TeV, obtained from the analysis of the four charged lepton final state l⁺l⁻l'⁺l'⁻ (l, l'=e or μ). We observe ten candidate events with an expected background of 0.37±0.13 events. The measured cross section σ(pp̄→ZZ)=1.26+0.47-0.37(stat)±0.14(syst) pb is in agreement with NLO QCD predictions. This result is combined with a previous result from the ZZ→l⁺l⁻νν¯ channel resulting in a combined cross section of σ(pp̄→ZZ)=1.40+0.43-0.37(stat)±0.14(syst) pb.
