1  AAD 2021AT based on 20.2 fb${}^{-1}$ of data. In this single lepton channel, only single neutrino is emitted, so that both ${{\mathit W}}$ and ${{\mathit t}}$ can be reconstructed. A neural network is trained to separate signal from background. The measured cross section agrees with the NLO+NNLL SM prediction of $22.4$ $\pm0.6$(scale)$\pm1.4$(PDF) pb.
2  AABOUD 2019R based on 12.2 to 20.3 fb${}^{-1}$ of data from ATLAS and CMS at 8 TeV.
3  AAD 2016B based on 20.3 fb${}^{-1}$ of data. The result gives $\vert \mathit V_{\mathit tb}\vert $ = $1.01$ $\pm0.10$ and $\vert \mathit V_{\mathit tb}\vert $ $>$ 0.80 (95$\%$ CL) without assuming unitarity of the CKM matrix. The results assume ${\mathit m}_{{{\mathit t}}}$ = 172.5 GeV for the acceptance.
4  Based on 12.2 fb${}^{-1}$ of data. Events with two oppositely charged leptons, large $\not E_T$ and a ${{\mathit b}}$-tagged jet are selected, and a multivariate analysis is used to separate the signal from the backgrounds. The result is consistent with the SM prediction of $22.2$ $\pm0.6$(scale)$\pm1.4$(PDF) pb at approximate NNLO.
