 Measurement of the $t\bar{t}W$ and $t\bar{t}Z$ production cross sections in $pp$ collisions at $\sqrt{s} = 8$ TeV with the ATLAS detector. The production cross sections of top-quark pairs in association with massive vector bosons have been measured using $pp$ collision data corresponding to an integrated luminosity of 20.3/fb, collected by the ATLAS detector in 2012 at the LHC.
