Top Quark Charge Asymmetry Measurement with ATLAS at the LHC
In the Standard Model top-antitop pair production is foreseen to be charge asymmetric in quark-antiquark annihilation at NLO. Although the dominant ttbar production mechanism in pp collisions at the LHC is gluon-gluon fusion, QCD predicts a small excess of top quarks produced at higher absolute rapi...
