1  AABOUD 2019AR based on 35.9 fb${}^{-1}$ of data. ${{\mathit t}}{{\overline{\mathit t}}}{{\mathit W}}$ and ${{\mathit t}}{{\overline{\mathit t}}}{{\mathit Z}}$ cross sections are simultaneously measured using a combined fit to the events divided into multiple regions. The result is consistent with the SM prediction at NLO $0.60$ ${}^{+0.08}_{-0.07}$ pb. It is also used to constrain the Wilson coefficients for dimension-six operators which modify the ${{\mathit t}}{{\overline{\mathit t}}}{{\mathit Z}}$ vertex.
2  Based on 35.9 fb${}^{-1}$ of proton-proton data taken at $\sqrt {s }$ = 13 TeV. The result is consistent with the SM prediction and is used to constrain the Wilson coefficients for dimension-six operators describing new interactions. The result is consistent with the SM prediction at NLO $0.628$ $\pm0.082$ pb.
