AABOUD 2017BB based on 20.2 fb${}^{-1}$ of ${{\mathit p}}{{\mathit p}}$ data. Triple-differential decay rate of top quark is used to simultaneously determine five generalized ${{\mathit W}}{{\mathit t}}{{\mathit b}}$ couplings as well as the top polarization. ${{\mathit \alpha}_{{{{\mathit \ell}}}}}$ denotes the spin analyzing power of charged lepton, and the spin axis of the top polarization $\mathit P$ is taken along the spectator-quark momentum in the top rest frame. The value is compatible with the SM prediction of about 0.9.

AABOUD 2017I based on 20.2 fb${}^{-1}$ of ${{\mathit p}}{{\mathit p}}$ data. A cut-based analysis is used to discriminate between signal and backgrounds. $\alpha _{{{\mathit \ell}}}$ denotes the spin analyzing power of charged lepton, and the spin axis of the top polarization $\mathit P$ is taken along the spectator-quark momentum in the top rest frame. See this paper for a number of other asymmetries and measurements that are not included here.

AABOUD 2017I based on 20.2 fb${}^{-1}$ of ${{\mathit p}}{{\mathit p}}$ data. A cut-based analysis is used to discriminate between signal and backgrounds. $\mathit F_{\pm{}}$ denotes ${{\mathit W}}$ helicity fraction, and the spin axis of the top polarization $\mathit P$ is taken along the spectator-quark momentum in the top rest frame. See this paper for a number of other asymmetries and measurements that are not included here.

KHACHATRYAN 2016BO based on 19.7 fb${}^{-1}$ of data. A high-purity sample with a muon is selected by a multivariate analysis. The value is the top spin asymmetry, given by one half of the spin analyzing power $\alpha _{{{\mathit \mu}}}$ (=1 at LO of SM) times the top polarization, $\mathit P$, where the spin axis is defined as the direction of the untagged jet in the top rest frame. The value is compatible with the SM prediction of 0.44 with a 2.0$\sigma $ deviation.
