Abstract

The cross section of the ttZ and ttW processes are measured in a simultaneous fit using 36.1 fb^-1 of proton-proton collisions at a centre of mass energy of √(s)=13 TeV recorded by the ATLAS detector at the LHC. The result is found to be σ_ttZ = 0.95 ± 0.08 (stat.) ± 0.10 (syst.) pb and σ_ttW = 0.87 ± 0.13 (stat.) ± 0.14 (syst.) pb and compatible with the Standard Model.
