Measurement of the ZZ diboson cross section using the leptonic decay mode with the ATLAS detector

A measurement of the $Z^{0}Z^{0}$ diboson cross section is presented using a data sample corresponding to up to $5 \* fb^{-1}$ of integrated luminosity collected at $\sqrt{s} = 7$ TeV by the ATLAS detector at the LHC in 2011. In this dataset two Z bosons decaying leptonically to electrons and/or muons are observed. Results on the triple gauge couplings will also be presented.
