The charge asymmetry in top quark pair production in the di-lepton ttˉ channel using the ATLAS experiment at Large Hadron Collider is presented. The asymmetry is studied in the distribution of absolute rapidity difference between top and anti-top. The reconstruction of the ttˉ system is based on a leading order matrix element. The lepton charge asymmetry is also presented. All results are consistent with the Standard Model.The charge asymmetry in top quark pair production in the di-lepton ttˉ channel using the ATLAS experiment at Large Hadron Collider is presented.
