1  AAD 2016AE is based on 20.3 fb${}^{-1}$ of data. After kinematic reconstruction, the top quark momenta are corrected for detector resolution and acceptance effects by unfolding, using parton level information of the MC generators. The lepton charge asymmetry is measured as A${}^{ {{\mathit \ell}} {{\mathit \ell}} }_{C}$ = $0.008$ $\pm0.006$. All the measurements are consistent with the SM predictions.
2  AAD 2016AZ based on 20.3 fb${}^{-1}$ of data. All the differential and inclusive measurements are statistically limited and consistent with the SM predictions.
3  AAD 2016T based on 20.3 fb${}^{-1}$ of data. Uses reconstruction techniques for the decay topology of highly boosted top quarks. The observed asymmetry is transformed by unfolding to a parton-level result in the shown fiducial region. The result is consistent with the NLO SM prediction.
4  KHACHATRYAN 2016AD based on 19.5 fb${}^{-1}$ of data. The lepton charge asymmetry is measured as A${}^{ {{\mathit \ell}} {{\mathit \ell}} }_{C}$ = $0.003$ $\pm0.006$ $\pm0.003$. All the measurements are consistent with the SM predictions.
5  KHACHATRYAN 2016AH based on 19.6 fb${}^{-1}$ of data. The same data set as in KHACHATRYAN 2016T is used. A template technique is used, which is sensitive to the charge anti-symmetric component of the ${{\mathit t}}{{\overline{\mathit t}}}$ rapidity distributions and statistically advantageous. The result is consistent with the SM predictions.
6  KHACHATRYAN 2016T based on 19.7 fb${}^{-1}$ of data. The same data set as in KHACHATRYAN 2016AH is used. After kinematic reconstruction the top quark momenta are corrected for detector resolution and acceptance effects by unfolding, using parton level information of the MC generators. All the measurements are consistent with the SM predictions.
