Inclusive and differential measurements as a function of the invariant mass, transverse momentum, and longitudinal boost of the $t\\bar{t}$ system are performed both in the full phase space and in a fiducial phase space closely matching the detector acceptance. Two observables are studied: $A_{ll}^{C}$ based on the selected leptons and $A_{t\\bar{t}}^C$ based on the reconstructed $t\\bar{t}$ final state. The inclusive asymmetries are measured in the full phase space to be $A_{ll}^{C} =0.008 \\pm 0.006$ and $A_{t\\bar{t}}^C = 0.021 \\pm 0.016$, which are in agreement with the Standard Model predictions of  $A_{ll}^{C} = 0.0064 \\pm 0.0003$ and $A_{t\\bar{t}}^C = 0.0111 \\pm 0.0004$.","hasPart":[{"@id":"https://doi.org/10.17182/hepdata.77033.v1/t1","@type":"Dataset","description":"Unfolded distribution for the inclusive $\\Delta|\\eta|$ observable in the fiducial volume.","name":"Table 1"},{"@id":"https://doi.org/10.17182/hepdata.77033.v1/t2","@type":"Dataset","description":"Unfolded distribution for the inclusive $\\Delta|y|$ observable in the fiducial volume.","name":"Table 2"},{"@id":"https://doi.org/10.17182/hepdata.77033.v1/t3","@type":"Dataset","description":"The leptonic inclusive asymmetry in the fiducial volume.","name":"Table 3"},{"@id":"https://doi.org/10.17182/hepdata.77033.v1/t4","@type":"Dataset","description":"The leptonic asymmetry dependence on the invariant mass of top-antitop system ($m_{t\\bar{t}}$) in the fiducial volume.","name":"Table 4"},{"@id":"https://doi.org/10.17182/hepdata.77033.v1/t5","@type":"Dataset","description":"The leptonic asymmetry dependence on the longitudinal boost of the top-antitop system ($\\beta_z^{t\\bar{t}}$) in the fiducial volume.","name":"Table 5"},{"@id":"https://doi.org/10.17182/hepdata.77033.v1/t6","@type":"Dataset","description":"The leptonic asymmetry dependence on the transverse momentum of the top-antitop system ($p_T^{t\\bar{t}}$) in the fiducial volume.","name":"Table 6"},{"@id":"https://doi.org/10.17182/hepdata.77033.v1/t7","@type":"Dataset","description":"The top-antitop inclusive asymmetry in the fiducial volume.","name":"Table 7"},{"@id":"https://doi.org/10.17182/hepdata.77033.v1/t8","@type":"Dataset","description":"The top-antitop asymmetry dependence on the invariant mass of top-antitop system ($m_{t\\bar{t}}$) in the fiducial volume.","name":"Table 8"},{"@id":"https://doi.org/10.17182/hepdata.77033.v1/t9","@type":"Dataset","description":"The top-antitop asymmetry dependence on the longitudinal boost of the top-antitop system ($\\beta_z^{t\\bar{t}}$) in the fiducial volume.","name":"Table 9"},{"@id":"https://doi.org/10.17182/hepdata.77033.v1/t10","@type":"Dataset","description":"The top-antitop asymmetry dependence on the transverse momentum of the top-antitop system ($p_T^{t\\bar{t}}$) in the fiducial volume.","name":"Table 10"}],"identifier":[{"@type":"PropertyValue","propertyID":"HEPDataRecord","value":"https://www.hepdata.net/record/ins1449082?version=1"},{"@type":"PropertyValue","propertyID":"HEPDataRecordAlt","value":"https://www.hepdata.net/record/77033"}],"inLanguage":"en","name":"Measurements of the charge asymmetry in top-quark pair production in the dilepton final state at $\\sqrt{s}=8$ TeV with the ATLAS detector","provider":{"@type":"Organization","name":"HEPData"},"publisher":{"@type":"Organization","name":"HEPData"},"url":"https://www.hepdata.net/record/ins1449082?version=1","version":1}
