The topological charge is measured on gauge configurations generated with a renormalization group improved gauge action and a mean field improved clover quark action at three values of β=6/g 2 with four sea quark masses at each β. The lattice spacings at these β ’s are a≈0.22, 0.16 and 0.11 fm at the physical up and down quark mass, which are fixed by the physical ρ meson mass. The study is supplemented by simulations of pure SU(3) gauge theory with the same gauge action at 5 values of β with lattice spacings 0.09 fm≲a≲0.27 fm. We employ a field-theoretic definition of the topological charge together with cooling. For the topological susceptibility in the continuum limit of pure SU(3) gauge theory we obtain χ 1/4 t =197 +13 -16 MeV where the error shows statistical and systematic ones added in quadrature. In full QCD χ t at heavy sea quark masses is consistent with that of pure SU(3) gauge theory. A decrease of χ t toward light quark masses, as predicted by the anomalous Ward-Takahashi identity for U(1) chiral symmetry, becomes clearer for smaller lattice spacings. The cross over in the behavior of χ t from heavy to light sea quark masses is discussed.","subitem_description_type":"Abstract"}]},"item_5_publisher_7":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"American Physical Society"}]},"item_5_relation_14":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"info:doi/10.1103/PhysRevD.64.114501","subitem_relation_type_select":"DOI"}}]},"item_5_rights_15":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"(C) 2001 American Physical Society"}]},"item_5_select_19":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_select_item":"publisher"}]},"item_5_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_5_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"15507998","subitem_source_identifier_type":"ISSN"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Khan, A.Ali"}],"nameIdentifiers":[{"nameIdentifier":"18591","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Aoki, S."}],"nameIdentifiers":[{"nameIdentifier":"18592","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Burkhalter, R."}],"nameIdentifiers":[{"nameIdentifier":"18593","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Ejiri, S."}],"nameIdentifiers":[{"nameIdentifier":"18594","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Fukugita, M."}],"nameIdentifiers":[{"nameIdentifier":"18595","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Hashimoto, S."}],"nameIdentifiers":[{"nameIdentifier":"18596","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Ishizuka, N."}],"nameIdentifiers":[{"nameIdentifier":"18597","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Iwasaki, Y."}],"nameIdentifiers":[{"nameIdentifier":"18598","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Kanaya, K."}],"nameIdentifiers":[{"nameIdentifier":"18599","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Kaneko, T."}],"nameIdentifiers":[{"nameIdentifier":"18600","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Kuramashi, Y."}],"nameIdentifiers":[{"nameIdentifier":"18601","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Manke, T."}],"nameIdentifiers":[{"nameIdentifier":"18602","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Nagai, K.I."}],"nameIdentifiers":[{"nameIdentifier":"18603","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Okawa, M."}],"nameIdentifiers":[{"nameIdentifier":"18604","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Shanahan, H.P."}],"nameIdentifiers":[{"nameIdentifier":"18605","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Ukawa, A."}],"nameIdentifiers":[{"nameIdentifier":"18606","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Yoshie, T."}],"nameIdentifiers":[{"nameIdentifier":"18607","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"CP-PACS, Collaboration"}],"nameIdentifiers":[{"nameIdentifier":"18608","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":"2019-07-29"}],"displaytype":"detail","filename":"64_11_114501.pdf","filesize":[{"value":"985.2 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"64_11_114501.pdf","url":"https://niigata-u.repo.nii.ac.jp/record/2366/files/64_11_114501.pdf"},"version_id":"5f8821dd-bda0-4e76-9ef4-af6895717e7a"}]},"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":"Topological susceptibility in lattice QCD with two flavors of dynamical quarks","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Topological susceptibility in lattice QCD with two flavors of dynamical quarks"},{"subitem_title":"Topological susceptibility in lattice QCD with two flavors of dynamical quarks","subitem_title_language":"en"}]},"item_type_id":"5","owner":"1","path":["454","489"],"pubdate":{"attribute_name":"公開日","attribute_value":"2014-06-23"},"publish_date":"2014-06-23","publish_status":"0","recid":"2366","relation_version_is_last":true,"title":["Topological susceptibility in lattice QCD with two flavors of dynamical quarks"],"weko_creator_id":"1","weko_shared_id":null},"updated":"2022-12-15T03:35:19.154093+00:00"}
