Top-quark pair production in association with a $W$ or $Z$ boson with the ATLAS experiment
The cross section of the $t\bar{t}Z$ and $t\bar{t}W$ processes are measured in a simultaneous fit using 36.1 $\text{fb}^{-1}$ of proton-proton collisions at a centre of mass energy of $\sqrt{s}=13\ \text{TeV}$ recorded by the ATLAS detector at the LHC. The result is found to be $\sigma_{t\bar{t}Z} =...

| description | The cross section of the $t\bar{t}Z$ and $t\bar{t}W$ processes are measured in a simultaneous fit using 36.1 $\text{fb}^{-1}$ of proton-proton collisions at a centre of mass energy of $\sqrt{s}=13\ \text{TeV}$ recorded by the ATLAS detector at the LHC. The result is found to be $\sigma_{t\bar{t}Z} = 0.95 \pm 0.08 \text{ (stat.)} \pm 0.10 \text{ (syst.)}\,\text{pb}$ and $\sigma_{t\bar{t}W} = 0.87 \pm 0.13 \text{ (stat.)} \pm 0.14 \text{ (syst.)}\,\text{pb}$ and compatible with the Standard Model. |
