The analysis uses a data sample of proton-proton collisions at s v =13 TeV recorded with the ATLAS detector at the Large Hadron Collider in 2015, corresponding to a total integrated luminosity of 3.2 fb -1 . The inclusive cross sections are extracted using likelihood fits to signal and control regions, resulting in s tt¯Z =0.9±0.3 pb and s tt¯W =1.5±0.8 pb, in agreement with the Standard Model predictions.
