Abstract
Measurements of the top-antitop quark pair production charge asymmetry in the dilepton channel, characterized by two high- leptons (electrons or muons), are presented using data corresponding to an integrated luminosity of from collisions at a center-of-mass energy collected with the ATLAS detector at the Large Hadron Collider at CERN. Inclusive and differential measurements as a function of the invariant mass, transverse momentum, and longitudinal boost of the system are performed both in the full phase space and in a fiducial phase space closely matching the detector acceptance. Two observables are studied: based on the selected leptons and based on the reconstructed final state. The inclusive asymmetries are measured in the full phase space to be and , which are in agreement with the Standard Model predictions of and .
