AABOUD 2017BB based on 20.2 fb${}^{-1}$ of ${{\mathit p}}{{\mathit p}}$ data at $\sqrt {s }$ = 8 TeV. Triple-differential decay rate of top quark in the ${{\mathit t}}$-channel single-top production is used to simultaneously determine five generalized ${{\mathit W}}{{\mathit t}}{{\mathit b}}$ couplings as well as the top polarization. No assumption is made for the other couplings. The authors reported ${{\mathit f}_{{1}}}$ = $0.30$ $\pm0.05$ and ${{\mathit f}_{{1}}^{+}}$ $<$ $0.120$ which we converted to ${{\mathit F}_{{+}}}$ = ${{\mathit f}_{{1}}}{{\mathit f}_{{1}}^{+}}$. See this paper for constraints on other couplings not included here.

The statstical errors of F$_{0}$ and F$_{+}$ are correlated with correlation coefficient $\rho (F_{0},F_{+}$) = $-0.69$.

Results are based on 5.4 fb${}^{-1}$ of data in ${{\mathit p}}{{\overline{\mathit p}}}$ collisions at 1.96 TeV, including those of ABAZOV 2008B. Under the SM constraint of ${{\mathit f}_{{0}}}$ = 0.698 (for ${\mathit m}_{{{\mathit t}}}$ = 173.3 GeV, ${\mathit m}_{{{\mathit W}}}$ = 80.399 GeV), ${{\mathit f}_{{+}}}$ = $0.010$ $\pm0.022$ $\pm0.030$ is obtained.

AFFOLDER 2000B studied the angular distribution of leptonic decays of ${{\mathit W}}$ bosons in ${{\mathit t}}$ $\rightarrow$ ${{\mathit W}}{{\mathit b}}$ events. The ratio $\mathit F_{0}$ is the fraction of the helicity zero (longitudinal) ${{\mathit W}}~$bosons in the decaying top quark rest frame. B( ${{\mathit t}}$ $\rightarrow$ ${{\mathit W}}_{+}$ ${{\mathit b}}$ ) is the fraction of positive helicity (right-handed) positive charge ${{\mathit W}}~$bosons in the top quark decays. It is obtained by assuming the Standard Model value of $\mathit F_{0}$.

Based on 2.7 and 5.1 fb${}^{-1}$ of CDF data in ${{\mathit \ell}}$ + jets and dilepton channels, and 5.4 fb${}^{-1}$ of D0 data in ${{\mathit \ell}}$ + jets and dilepton channels. ${{\mathit F}_{{0}}}$ = $0.682$ $\pm0.035$ $\pm0.046$ if ${{\mathit F}_{{+}}}$ = 0.0017(1), while ${{\mathit F}_{{+}}}$ = $-0.015$ $\pm0.018$ $\pm0.030$ if ${{\mathit F}_{{0}}}$ = 0.688(4), where the assumed fixed values are the SM prediction for ${\mathit m}_{{{\mathit t}}}$ = $173.3$ $\pm1.1$ GeV and ${\mathit m}_{{{\mathit W}}}$ = $80.399$ $\pm0.023$ GeV.

Results are based on 2.7 fb${}^{-1}$ of data in ${{\mathit p}}{{\overline{\mathit p}}}$ collisions at $\sqrt {s }$ = 1.96 TeV. ${{\mathit F}_{{0}}}$ result is obtained by assuming ${{\mathit F}_{{+}}}$ = 0, while ${{\mathit F}_{{+}}}$ result is obtained for ${{\mathit F}_{{0}}}$ = 0.70, the SM value. Model independent fits for the two fractions give ${{\mathit F}_{{0}}}$ = $0.88$ $\pm0.11$ $\pm0.06$ and ${{\mathit F}_{{+}}}$ = $-0.15$ $\pm0.07$ $\pm0.06$ with correlation coefficient of $-0.59$. The results are for ${\mathit m}_{{{\mathit t}}}$ = 175 GeV.

Model independent fits for the two fractions give ${{\mathit F}_{{0}}}$ = $0.66$ $\pm0.16$ $\pm0.05$ and ${{\mathit F}_{{+}}}$ = $-0.03$ $\pm0.06$ $\pm0.03$.

ABAZOV 2005L studied the angular distribution of leptonic decays of ${{\mathit W}}$ bosons in ${{\mathit t}}{{\overline{\mathit t}}}$ events, where one of the ${{\mathit W}}$'s from ${{\mathit t}}$ or ${{\overline{\mathit t}}}$ decays into ${{\mathit e}}$ or ${{\mathit \mu}}$ and the other decays hadronically. The fraction of the ``+'' helicity ${{\mathit W}}$ boson is obtained by assuming ${{\mathit F}_{{0}}}$ = 0.7, which is the generic prediction for any linear combination of V and A currents. Based on $230$ $\pm15$ pb${}^{-1}$ of data at $\sqrt {s }$ = 1.96 TeV.

ACOSTA 2005D measures the ${{\mathit m}^{2}}_{ {{\mathit \ell}} {+} {{\mathit b}} }$ distribution in ${{\mathit t}}{{\overline{\mathit t}}}$ production events where one or both ${{\mathit W}}$'s decay leptonically to ${{\mathit \ell}}$ = ${{\mathit e}}$ or ${{\mathit \mu}}$, and finds a bound on the V+A coupling of the ${{\mathit t}}{{\mathit b}}{{\mathit W}}$ vertex. By assuming the SM value of the longitudinal ${{\mathit W}}$ fraction ${{\mathit F}_{{0}}}$ = B( ${{\mathit t}}$ $\rightarrow$ ${{\mathit W}_{{0}}}{{\mathit b}}$ ) = 0.70, the bound on ${{\mathit F}}_{+}$ is obtained. If the results are combined with those of AFFOLDER 2000B, the bounds become ${{\mathit F}}_{V+A}$ $<$ 0.61 (95$\%$ CL) and ${{\mathit F}_{{+}}}$ $<$ 0.18 (95 $\%$CL), respectively. Based on $109$ $\pm7$ pb${}^{-1}$ of data at $\sqrt {s }$ = 1.8 TeV (run I).
