The asymmetry is characterized by the rapidity difference between top quarks and antiquarks (Δy) and measured in the final state with two charged leptons (electrons and muons). The inclusive asymmetry corrected to the entire phase space at parton level is measured to be Att￣FB=0.12±0.13 consistent with the expectations from the standard model (SM) and previous CDF results in the final state with a single charged lepton. The combination of the CDF measurements of the inclusive Att￣FB in both final states yields Att￣FB=0.160±0.045 which is consistent with the SM predictions. We also measure the differential asymmetry as a function of Δy. A linear fit to Att￣FB(|Δy|) assuming zero asymmetry at Δy=0 yields a slope of α=0.14±0.15 consistent with the SM prediction and the previous CDF determination in the final state with a single charged lepton. The combined slope of Att￣FB(|Δy|) in the two final states is α=0.227±0.057 which is 2.0σ larger than the SM prediction.","subitem_description_language":"en","subitem_description_type":"Abstract"}]},"item_5_publisher_27":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"American Physical Society","subitem_publisher_language":"en"}]},"item_5_relation_11":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type":"isIdenticalTo","subitem_relation_type_id":{"subitem_relation_type_id_text":"https://doi.org/10.1103/PhysRevD.93.112005","subitem_relation_type_select":"DOI"}}]},"item_5_rights_12":{"attribute_name":"権利情報","attribute_value_mlt":[{"subitem_rights":"(c) 2016 American Physical Society","subitem_rights_language":"ja"}]},"item_5_source_id_7":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"2470-0010","subitem_source_identifier_type":"PISSN"}]},"item_5_source_id_9":{"attribute_name":"NCID","attribute_value_mlt":[{"subitem_source_identifier":"AA00773624","subitem_source_identifier_type":"NCID"}]},"item_5_subject_20":{"attribute_name":"NIIサブジェクト","attribute_value_mlt":[{"subitem_subject":"物理学","subitem_subject_scheme":"Other"}]},"item_access_right":{"attribute_name":"アクセス権","attribute_value_mlt":[{"subitem_access_right":"open access","subitem_access_right_uri":"http://purl.org/coar/access_right/c_abf2"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"CD Collaboration","creatorNameLang":"en"}]},{"creatorNames":[{"creatorName":"Hara K.","creatorNameLang":"en"}]},{"creatorNames":[{"creatorName":"Ki S.
