摘要：
This report presents a measurement of the ZZ llll production cross section performed by the ATLAS detector in LHC proton-proton collisions at root s = 7TeV. Three ZZ decay channels are considered: eeee, ee mu mu or mu mu mu mu, including also leptons produced in the t 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 similar to 1 fb-1 are also presented.
