1  SIRUNYAN 2020D based on 35.9 fb${}^{-1}$ of data. Different categories of jet and b jet multiplicity and multivariate discriminators are used to separate signal and background events. The cross section ratio is measured to be ${\mathit \sigma (}$ ${{\mathit t}}{{\mathit q}}{)}/{\mathit \sigma (}$ ${{\overline{\mathit t}}}{{\mathit q}}{)}$ = $1.68$ $\pm0.02$ $\pm0.05$. CKM matrix element is obtained as $\vert $f$_{LV}\mathit V_{\mathit tb}\vert $ = $0.98$ $\pm0.07$(exp)$\pm0.02$(theo) where f$_{LV}$ is an anomalous form factor. All results are in agreement with the SM.
2  AABOUD 2017H based on 3.2 fb${}^{-1}$ of data. A maximum-likelihood fit to neural-network discriminant distributions is used to separate signal and background events. The third error is for luminosity. The cross section ratio is measured to be ${\mathit \sigma (}$ ${{\mathit t}}{{\mathit q}}{)}/{\mathit \sigma (}$ ${{\overline{\mathit t}}}{{\mathit q}}{)}$ = $1.72$ $\pm0.09$ $\pm0.18$. A lower limit $\vert \mathit V_{\mathit tb}\vert $ $>$ 0.84 (95$\%$ CL) is obtained. All results are in agreement with the SM.
3  SIRUNYAN 2017AA based on 2.2 fb${}^{-1}$ of data. A multivariate discriminator is used to separate signal and background events. The four errors are from statitics, experimental systematics, theory, and luminosity. The cross section ratio is measured to be ${\mathit \sigma (}$ ${{\mathit t}}{{\mathit q}}{)}/{\mathit \sigma (}$ ${{\overline{\mathit t}}}{{\mathit q}}{)}$ = $1.81$ $\pm0.18$ $\pm0.15$. CKM matrix element is obtained as $\vert \mathit V_{\mathit tb}\vert $ = $1.05$ $\pm0.07$(exp)$\pm0.02$(theo). All results are in agreement with the SM.
