The background prediction is shown after the combined likelihood fit to data under the background-only hypothesis across all control region and signal region categories.

Observed 95$\%$ CL lower limits from the combination of the pair-production channels on the mass of vector-like quarks for all combinations of BRs for $B\rightarrow Zb$, $B\rightarrow Hb$, $B\rightarrow Wt$, adding up to unity.

Upper limits at 95$\%$ CL on the cross section times BR to $Zt$ of single production (SP) of a $T$-quark. The expected limits are shown for the combination of the channels, as are the observed limits. The expected cross section times BR to $Zt$ for single-$T$-quark production is also shown for a coupling $\kappa_T = 0.5$, which corresponds to a coupling of $c_W = \sqrt{c^2_{W,L} + c^2_{W,R}} = 0.45$ from Ref. [14]. The BR assumed here corresponds to the singlet benchmark model, i.e. $\approx 25\%$.

Expected and observed 95$\%$ CL limits from the combination of the single-production channels on the coupling of the $T$ quark to SM particles, $c_W = \sqrt c^2_L + c^2_R$, assuming the singlet-model BR of $\approx 25\%$, as a function of the mass of the $T$ quark, $m_T$. Values of $c_W$ larger than the observed limit are excluded.

Expected and observed 95$\%$ CL limits from the combination of the single-production channels on the mixing angle in the singlet model between the $T$ quark and the top quark, $|\sin\theta_L|$, as a function of the mass of the $T$ quark, $m_T$. Values of $|\sin\theta_L|$ enclosed by the observed limit are excluded, i.e. for $m_T$ larger than $\approx 1200$ GeV, no value of $|\sin\theta_L|$ is excluded.

Expected lower limit from the combination of the single-production channels on the mass of the $T$ quark as a function of the couplings of the $T$ quark to the $W$ boson, $\sqrt c^2_L + c^2_R$, and to the $Z$ boson, $\sqrt c^2_L + c^2_R$ with the assumption of equal BRs for $T\rightarrow Zt$ and $T\rightarrow Ht$ in the limit of large $T$-quark masses.
