${{\boldsymbol t}}{{\overline{\boldsymbol t}}}$ Charge Asymmetry (A$_{C}$) in ${{\boldsymbol p}}{{\boldsymbol p}}$ Collisions at $\sqrt {s }$ = 7 TeV INSPIRE search

A$_{C}$ = (N($\Delta \vert $y$\vert >$0) $−$ N($\Delta \vert $y$\vert <$0) ) $/$ (N($\Delta \vert $y$\vert >$0) + N($\Delta \vert $y$\vert <$0) ) where $\Delta \vert $y$\vert $ = $\vert $y$_{{{\mathit t}}}\vert $ $−$ $\vert $y$_{{{\overline{\mathit t}}}}\vert $ is the difference between the absolute values of the top and antitop rapidities and N is the number of events with $\Delta \vert $y$\vert $ positive or negative.

1  AAD 2015AJ based on 4.6 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${}^{{{\mathit \ell}}}_{C}$ = $0.024$ $\pm0.015$ $\pm0.009$. All the measurements are consistent with the SM predictions.
2  Based on 4.7 fb${}^{-1}$ of data. The result is consistent with the SM prediction of A$_{C}$ = $0.0123$ $\pm0.0005$. The asymmetry is $0.011$ $\pm0.018$ if restricted to those events where $\beta _{Z}$( ${{\mathit t}}{{\overline{\mathit t}}}$ ) $>$ 0.6, which is also consistent with the SM prediction of $0.020$ ${}^{+0.006}_{-0.007}$.
3  Based on 5.0 fb${}^{-1}$ of data. The lepton charge asymmetry is measured as A${}^{{{\mathit \ell}}}_{C}$ = $0.009$ $\pm0.0010$ $\pm0.006$. A${}^{{{\mathit \ell}}}_{C}$ dependences on ${\mathit m}_{ {{\mathit t}} {{\overline{\mathit t}}} }$, $\vert $y( ${{\mathit t}}{{\overline{\mathit t}}}$ )$\vert $, and ${{\mathit p}_{{T}}}$( ${{\mathit t}}{{\overline{\mathit t}}}$ ) are given in Fig. 5. All measurements are consistent with the SM predictions.
4  Based on 1.04 fb${}^{-1}$ of data. The result is consistent with A$_{C}$ = $0.006$ $\pm0.002$ (MC at NLO). No significant dependence of A$_{C}$ on ${\mathit m}_{\mathrm { {{\mathit t}} {{\overline{\mathit t}}} }}$ is observed.
5  Based on 5.0 fb${}^{-1}$ of data at 7 TeV.
6  Based on 1.09 fb${}^{-1}$ of data. The result is consistent with the SM predictions.
