¹¹AAD 14AY used $\sigma(t\bar{t})$ for $e\mu$ events. The result is a combination of the measurements $m_t = 171.4 \pm 2.6$ GeV based on 4.6 fb⁻¹ of data at 7 TeV and $m_t = 174.1 \pm 2.6$ GeV based on 20.3 fb⁻¹ of data at 8 TeV.

¹²CHATRCHYAN 14 used $\sigma(t\bar{t})$ from pp collisions at $\sqrt{s} = 7$ TeV measured in CHATRCHYAN 12AX to obtain $m_t$ (pole) for $\alpha_s(m_Z) = 0.1184 \pm 0.0007$. The errors have been corrected in KHACHRYAN 14k.

¹ Based on 20.2 fb⁻¹ of $p\bar{p}$ data at $\sqrt{s} = 8$ TeV. $\Gamma_t$ is measured using a template fit to the reconstructed invariant mass of the b-jet of the semileptonically decaying top quark and the corresponding lepton, and the angular distance between $J_p$ and $J_f$ in hadronic top decay. Signal templates are generated by reweighting events at parton-level to Breit-Wigner distribution with different $\Gamma_t$ hypotheses for $m_t = 172.5$ GeV. The result is consistent with the NNLO SM prediction of 1.322 GeV.

² Based on 19.7 fb⁻¹ of $p\bar{p}$ data at $\sqrt{s} = 8$ TeV. The result is obtained by combining the measurement of $R = \Gamma(t \to Wb)/\Gamma(t \to Wq(q=b,s,d))$ and a previous CMS measurement of the t-channel single top production cross section of CHATRCHYAN 12BQ, by using the theoretical calculation of $\Gamma(t \to Wb)$ for $m_t = 172.5$ GeV.

³ Based on 5.4 fb⁻¹ of data in $p\bar{p}$ collisions at 1.96 TeV. $\Gamma(t \to Wb) = 1.87^{+0.44}_{-0.40}$ GeV is obtained from the observed t-channel single top quark production cross section, whereas $B(t \to bW) = 0.90 \pm 0.04$ is used assuming $\sum_q B(t \to qW) = 1$. The result is valid for $m_t = 172.5$ GeV. See the paper for the values for $m_t = 170$ or 175 GeV.

⁴ Based on 8.7 fb⁻¹ of data. The two sided 68% CL interval is 1.10 GeV < $\Gamma_t$ < 4.05 GeV for $m_t = 172.5$ GeV.

⁵ Based on 2.3 fb⁻¹ in $p\bar{p}$ collisions at $\sqrt{s} = 1.96$ TeV. ABAZOV 11B extracted $\Gamma_t$ from the partial width $\Gamma(t \to Wb) = 1.92^{+0.58}_{-0.51}$ GeV measured using the t-channel single top production cross section, and the branching fraction $br_t \to Wb = 0.962^{+0.068}_{-0.066}(\text{stat})^{+0.064}_{-0.052}(\text{syst})$. The $\Gamma(t \to Wb)$ measurement gives the 95% CL lowerbound of $\Gamma(t \to Wb)$ and hence that of $\Gamma_t$.

⁶ Results are based on 4.3 fb⁻¹ of data in $p\bar{p}$ collisions at $\sqrt{s} = 1.96$ TeV. The top quark mass and the hadronically decaying W boson are reconstructed for each candidate events and compared with templates of different top quark width. The two sided 68% CL interval is 0.3 GeV < $\Gamma_t$ < 4.4 GeV for $m_t = 172.5$ GeV.

⁷ Based on 955 pb⁻¹ of $p\bar{p}$ collision data at $\sqrt{s} = 1.96$ TeV. AALTONEN 09M selected $t\bar{t}$ candidate events for the $\ell + \not{E}_T +$ jets channel with one or two b-tags, and examine the decay width dependence of the reconstructed $m_t$ distribution. The result is for $m_t = 175$ GeV, whereas the upper limit is lower for smaller $m_t$.

¹ Based on 8.7 fb⁻¹ of data. This measurement gives $|V_{tb}| = 0.93 \pm 0.04$ and $|V_{tb}| > 0.85$ (95% CL) in the SM.

² Based on 19.7 fb⁻¹ of $p\bar{p}$ data at $\sqrt{s} = 8$ TeV. The result is obtained by counting the number of b jets per $t\bar{t}$ signal events in the dilepton channel. The $t\bar{t}$ production cross section is measured to be $\sigma(t\bar{t}) = 238 \pm 1 \pm 15$ pb, in good agreement with the SM prediction and the latest CMS measurement of CHATRCHYAN 14F. The measurement gives $R > 0.995$ (95% CL), or $|V_{tb}| > 0.975$ (95% CL) in the SM, requiring $R \le 1$.

³ Based on 8.7 fb⁻¹ of $p\bar{p}$ collisions at $\sqrt{s} = 1.96$ TeV. Measure the fraction of $t \to Wb$ decays simultaneously with the $t\bar{t}$ cross section. The correlation coefficient between those two measurements is -0.434. Assume unitarity of the 3x3 CKM matrix and set $|V_{tb}| > 0.89$ at 95% CL.

⁴ Based on 5.4 fb⁻¹ of data. The error is statistical and systematic combined. The result is a combination of 0.95 ± 0.07 from $\ell +$ jets channel and 0.86 ± 0.05 from $\ell\ell$ channel. $|V_{tb}| = 0.95 \pm 0.02$ follows from the result by assuming unitarity of the 3x3 CKM matrix.

⁵ Result is based on 0.9 fb⁻¹ of data. The 95% CL lower bound $R > 0.79$ gives $|V_{tb}| > 0.89$ (95% CL).

⁸AFFOLDER 01C measures the top-quark decay width ratio $R = \Gamma(W b)/\Gamma(W q)$, where $q$ is a $d$, $s$, or $b$ quark, by using the number of events with multiple b tags. The first error is statistical and the second systematic. A numerical integration of the likelihood function gives $R > 0.61$ (0.56) at 90% (95%) CL. By assuming three generation unitarity, $|V_{tb}| = 0.97^{+0.16}_{-0.12}$ or $|V_{tb}| > 0.78$ (0.75) at 90% (95%) CL is obtained. The result is based on 109 $\text{ pb}^{-1}$ of data at $\sqrt{s} = 1.8$ TeV.

¹SIRUNYAN 20V based on 35.9 $\text{ fb}^{-1}$ of $pp$ data at $\sqrt{s} = 13$ TeV. $t\bar{t}$ events are selected in the $t\bar{t} \to (\ell\nu\ell)(\tau\nu_\tau)b\bar{b}$ mode, where $\tau\nu_\tau$ refers to the hadronic decays of $\tau$. The branching ratio is determined with respect to the $t\bar{t}$ inclusive cross section extrapolated from the light dilepton mode. The ratio of the $t\bar{t}$ production cross sections in the $\ell\tau\tau$ and $\ell\tau$ channels yields 0.973 ± 0.009 ± 0.066, consistent with lepton universality.

²AAD 15CC based on 4.6 $\text{ fb}^{-1}$ of $pp$ data at $\sqrt{s} = 7$ TeV. The original value is given by $7.0 \pm 0.3 \pm 0.5\%$, which includes only the hadronic decay of $\tau$ leptons. It is assumed that the top branching ratios to leptons and jets add up to one and that only SM processes contribute to the background. The event selection criteria are optimized for the $\ell\tau\tau$ + jets channel. We have converted the original value to include lepton decays of $\tau$'s, by using the AAD 15CC measurements of the branching ratios to $e$ and $\mu$ channels, as well as the PDG values of $\tau$ branching ratios into $e$ and $\mu$ channels.

³Based on 9 $\text{ fb}^{-1}$ of data, the measurement is in the $t\bar{t} \to (b\ell\nu)(b\tau\nu)$, where $\tau$ decays into hadrons ($\tau\nu_\tau$), and $\ell$ ($e$ or $\mu$) include $\ell$ from $\tau$ decays ($\tau\ell$). The result is consistent with lepton universality.

No evidence for top production and its decay into $bW$ was found. The result is obtained for $m_t=175$ GeV when $B(\gamma c)=B(Zq)=0$, where $q$ is a $u$ or $c$ quark. Bounds on the effective $t-u\gamma$ and $t-u-Z$ couplings are found in their Fig. 4. The conversion to the constraint listed is from private communication, E. Gallo, January 2004.

⁴AAD 20B based on 81 $\text{ fb}^{-1}$ of data in $pp$ collisions at $\sqrt{s} = 13$ TeV. FCNC through single top production in association with a photon is searched for in the mode $\ell\gamma + \not{E}\bar{T} + 1J$ (b-tag). Anomalous FCNC left-handed and right-handed couplings are searched for, which result in different kinematical properties of top decay such as the lepton distribution. Limits are set on the $t\gamma q$ couplings in an effective field theory.

⁵AARON 09A looked for single top production via FCNC in $e^{\pm}p$ collisions at HERA with 474 $\text{ pb}^{-1}$. The upper bound of the cross section gives the bound on the FCNC coupling $\kappa_t u\gamma/\Lambda < 1.03$ TeV$^{-1}$, which corresponds to the result for $m_t = 175$ GeV.

⁶ABDALLAH 04C looked for single top production via FCNC in the reaction $e^{\pm}e^{-} \to \not{E}\bar{T} \text{ or } \bar{t}u$ in 541 $\text{ pb}^{-1}$ of data at $\sqrt{s}=189-208$ GeV. No deviation from the SM is found, which leads to the bound on $B(t \to \gamma q)$, where $q$ is a $u$ or $c$ quark, for $m_t = 175$ GeV when $B(t \to Zq)=0$ is assumed. The conversion to the listed bound is from private communication, O. Yushchenko, April 2005. The bounds on the effective $t-q\gamma$ and $t-q-Z$ couplings are given in their Fig. 7 and Table 4, for $m_t = 170-180$ GeV, where most conservative bounds are found by choosing the chiral couplings to maximize the negative interference between the virtual $\gamma$ and $Z$ exchange amplitudes.

⁷AKTAS 04 looked for single top production via FCNC in $e^{\pm}$ collisions at HERA with 118.3 $\text{ pb}^{-1}$, and found 5 events in the $e$ or $\mu$ channels. By assuming that they are due to statistical fluctuation, the upper bound on the $t\gamma\gamma$ coupling $\kappa_t u\gamma < 0.27$ (95% CL) is obtained. The conversion to the partial width limit, when $B(\gamma c) = B(Zu) = B(Zc) = 0$, is from private communication, E. Perez, May 2005.

⁸ACHARD 02J looked for single top production via FCNC in the reaction $e^{\pm}e^{-} \to \not{E}\bar{T} \text{ or } \bar{t}u$ in 634 $\text{ pb}^{-1}$ of data at $\sqrt{s} = 189-209$ GeV. No deviation from the SM is found, which leads to a bound on the top-quark decay branching fraction $B(\gamma q)$, where $q$ is a $u$ or $c$ quark. The bound assumes $B(Zq)=0$ and is for $m_t = 175$ GeV; bounds for $m_t=170$ GeV and 180 GeV and $B(Zq) \ne 0$ are given in Fig. 5 and Table 7.

2 ACGOSTA 05D measures the $m_t^2 + b$ distribution in $t\bar{t}$ production events where one or both W's decay leptonically to $\ell = e$ or $\mu$, and finds a bound on the $V+A$ coupling of the $t\bar{b}W$ vertex. By assuming the SM value of the longitudinal W fraction $F_0 = B(t \to W_0 b)$ = 0.70, the bound on $F_+$ is obtained. If the results are combined with those of AFFOLDER 00B, the bounds become $F_{V+A} < 0.61$ (95% CL) and $F_+ < 0.18$ (95% CL), respectively.

¹ AAD 22T based on 139 fb⁻¹ of pp data at $\sqrt{s}$ = 13 TeV. The results are obtained from the 95% CL upper limits on the single top-quark productions $\sigma(ug \to t) \cdot B(t \to bW) \cdot B(W \to \ell\nu) < 3.0$ pb and $\sigma(cg \to t) \cdot B(t \to bW) \cdot B(W \to \ell\nu) < 4.7$ pb. These are interpreted as limits on couplings in an EFT $|C_{uG}^{ut}|/\Lambda^2 < 0.057$ TeV⁻² and $|C_{uG}^{ct}|/\Lambda^2 < 0.14$ TeV⁻². The results also correspond to $B(t \to ug) < 6.1 \times 10^{-5}$ and $B(t \to cg) < 3.7 \times 10^{-4}$.

⁶ Based on 2.2 fb⁻¹ of data in $p\bar{p}$ collisions at $\sqrt{s}$ = 1.96 TeV. Upper limit of single top quark production cross section $\sigma(u(c) + g \to t) < 1.8$ pb (95% CL) via FCNC $t-u-g$ and $t-c-g$ couplings lead to the bounds. $B(t \to u+g) < 3.9 \times 10^{-4}$ and $B(t \to c+g) < 5.7 \times 10^{-3}$ follow.

⁷ Result is based on 230 pb⁻¹ of data at $\sqrt{s}$ = 1.96 TeV. Absence of single top quark production events via FCNC $t-u-g$ and $t-c-g$ couplings lead to the upper bounds on the dimensioned couplings, $\kappa^{utg}/\Lambda$ and $\kappa^{ctg}/\Lambda$, respectively.

The result gives $|V_{tb}| = 0.91 \pm 0.11(\text{stat}+\text{syst}) \pm 0.07(\text{theory})$, or $|V_{tb}| > 0.71$ at 95% CL.

Events with isolated ℓ + $E_T$ + ≥ 2 jets with 1 or 2 b-tags are analyzed and s- and t-channel single top events are selected by using boosted decision tree, Bayesian neural networks and the matrix element method. The signal has 5.0 sigma significance. The result gives $|V_{tb}| = 1.07 \pm 0.12$, or $|V_{tb}| > 0.78$ at 95% CL. The analysis assumes $m_t = 170$ GeV.

17 Result is based on 2.2 fb⁻¹ of data. Events with isolated ℓ + $E_T$ + 2, 3 jets with at least one b-tag are selected, and s- and t-channel single top events are selected by using likelihood, matrix element, and neural network discriminants. The result can be interpreted as $|V_{tb}| = 0.88_{-0.12}^{+0.13}(\text{stat}+\text{syst}) \pm 0.07(\text{theory})$, and $|V_{tb}| > 0.66$ (95% CL) under the $|V_{tb}| < 1$ constraint.

The result can be interpreted as the measurement of the CKM matrix element $|V_{tb}| = 1.31_{-0.21}^{+0.25}$, or $|V_{tb}| > 0.68$ (95% CL) under the $|V_{tb}| < 1$ constraint.

21 Result is based on 1 fb<sup>-1</sup> of data. The result is for m<sub>t</sub> = 170 GeV, and the mean value decreases with increasing m<sub>t</sub>; see their Fig. 2. The result is obtained after combining &ell; + jets, &ell;&ell;, and &ell;&tau; final states, and the ratios of the extracted cross sections are R<sub>&ell;&ell;</sub>/R<sub>&ell;&ell;</sub> = 0.86<sup>+0.19</sup><sub>-0.17</sub> and R<sub>&ell;&ell;</sub>/R<sub>&ell;&ell;</sub> = 0.97<sup>+0.32</sup><sub>-0.29</sub>, consistent with the SM expectation of R = 1. This leads to the upper bound of B(t &rarr; bH<sup>+</sup>) as a function of m<sub>H</sub>. Results are shown in their Fig. 1 for B(H<sup>+</sup> &rarr; &tau;&nu;) = 1 and B(H<sup>+</sup> &rarr; c&Upsilon;) = 1 cases.

Comparison of the m<sub>t</sub> dependence of the extracted cross section and a partial NNLO QCD prediction gives m<sub>t</sub> = 171.5<sup>+9.9</sup><sub>-8.8</sub> GeV. The &ell;&tau; channel alone gives 7.6<sup>+4.9</sup><sub>-3.5</sub> + 1.4 + 4.3 - 3.4 - 0.9 pb and the &ell;&ell; channel gives 7.5<sup>+1.2</sup><sub>-1.1</sub> + 0.7 + 0.7 &pm; 0.09 pb.

24 Result is based on 0.9 fb<sup>-1</sup> of data. The cross section is obtained from the &ell; + &ge; 3 jet event rates with 1 or 2 b-tag, and also from the kinematic likelihood analysis of the &ell; + 3, 4 jet events. The result is for m<sub>t</sub> = 172.6 GeV, and its m<sub>t</sub> dependence shown in Fig. 3 leads to the constraint m<sub>t</sub> = 170 &pm; 7 GeV when compared to the SM prediction.
25 Result is based on 360 pb⁻¹ of data. Events cross with high p_T oppositely charged dileptons ℓ⁺ℓ⁻ (ℓ = e, μ) are used to obtain cross sections for t<span style="text-decoration: overline">t</span>, W⁺W⁻, and Z → τ⁺τ⁻ production processes simultaneously. The other cross sections are given in Table IV.
