Using the framework of the operator product expansion supplemented by the renormalization group method, we derive the definite predictions for the moments of F2γ(x,Q2,P2) up to the next-to-next-to-leading order (NNLO) (the order ααs) and for the moments of FLγ(x,Q2,P2) up to the next-to-leading order (NLO) (the order ααs). The NNLO corrections to the sum rule of F2γ(x,Q2,P2) are negative and found to be 7%–10% of the sum of the LO and NLO contributions, when P2=1  GeV2 and Q2=30∼100  GeV2 or P2=3  GeV2 and Q2=100  GeV2, and the number of active quark flavors nf is three or four. The NLO corrections to FLγ are also negative. The moments are inverted numerically to obtain the predictions for F2γ(x,Q2,P2) and FLγ(x,Q2,P2) as functions of x.","subitem_description_type":"Abstract"}]},"item_2_full_name_2":{"attribute_name":"著者(ヨミ)","attribute_value_mlt":[{"nameIdentifiers":[{}],"names":[{"name":"ウエダ, タカヒロ"}]},{"nameIdentifiers":[{}],"names":[{"name":"ササキ, ケン"}]},{"nameIdentifiers":[{}],"names":[{"name":"ウエマツ, ツネオ"}]}]},"item_2_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{}],"names":[{}]}]},"item_2_publisher_35":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"American Physical Society"}]},"item_2_relation_13":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type":"isIdenticalTo","subitem_relation_type_id":{"subitem_relation_type_id_text":"10.1103/PhysRevD.75.114009","subitem_relation_type_select":"DOI"}}]},"item_2_source_id_11":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AA00773624","subitem_source_identifier_type":"NCID"}]},"item_2_text_4":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"Department of Physics, Faculty of Engineering, Yokohama National University = 横浜国立大学大学院工学研究院  知的構造の創生部門  物理科学と知の創造分野"},{"subitem_text_value":"Department of Physics, Faculty of Engineering, Yokohama National University"},{"subitem_text_value":"Department of Physics, Graduate School of Science, Kyoto University"}]},"item_2_version_type_18":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Ueda, Takahiro"}],"nameIdentifiers":[{"nameIdentifier":"17641","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Sasaki, Ken"}],"nameIdentifiers":[{"nameIdentifier":"17642","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Uematsu, Tsuneo"}],"nameIdentifiers":[{"nameIdentifier":"17643","nameIdentifierScheme":"WEKO"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2016-09-16"}],"displaytype":"detail","filename":"Phys.Rev.D75.pdf","filesize":[{"value":"590.5 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"Phys.Rev.D75.pdf","url":"https://ynu.repo.nii.ac.jp/record/3965/files/Phys.Rev.D75.pdf"},"version_id":"9254e618-335d-425d-b853-e2584a3650ab"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"eng"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"Virtual photon structure functions to the next-to-next-to-leading order in QCD","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Virtual photon structure functions to the next-to-next-to-leading order in QCD"}]},"item_type_id":"2","owner":"3","path":["496"],"pubdate":{"attribute_name":"公開日","attribute_value":"2011-03-28"},"publish_date":"2011-03-28","publish_status":"0","recid":"3965","relation_version_is_last":true,"title":["Virtual photon structure functions to the next-to-next-to-leading order in QCD"],"weko_creator_id":"3","weko_shared_id":-1},"updated":"2023-06-20T21:35:37.803225+00:00"}
