Abstract
This report presents a measurement of the ZZ → llll production cross section performed by the ATLAS detector in LHC proton-proton collisions at √s = 7TeV. Three ZZ decay channels are considered: eeee, eeμμ or μμμμ, including also leptons produced in the τ decay of the Z’s. The results are based on an integrated luminosity of 4.7 fb−1 collected by ATLAS in 2011 with a fully operational detector and stable beam conditions. Limits on ZZ anomalous triple gauge couplings derived using the cross section alone obtained with an integrated luminosity of ∼ 1 fb−1 are also presented.
