Chirally symmetric overlap fermion formulation is used to avoid the contamination from up and down quark contents due to an operator mixing between strange and light scalar operators, s ̅s and u ̅u + d ̅d . At a lattice spacing a=0.112(1) fm, we perform calculations at four values of degenerate up and down quark massesm_ud, which cover a range of the pion mass M_π≃300–540 MeV. We employ two different methods to calculate 〈N|s ̅s|N〉. One is a direct method where we calculate 〈N|s ̅s|N〉 by directly inserting the s ̅s operator. The other is an indirect method where 〈N|s ̅s|N〉 is extracted from a derivative of the nucleon mass in terms of the strange quark mass. With these two methods we obtain consistent results for 〈N|s ̅s|N〉 with each other. Our best estimate f_(t_s )=M_s 〈N|s ̅s|N〉/M_N=0.009〖(15)〗_stat 〖(16)〗_sys is in good agreement with our previous studies in two-flavor QCD.","subitem_description_language":"en","subitem_description_type":"Abstract"}]},"item_5_identifier_34":{"attribute_name":"URI","attribute_value_mlt":[{"subitem_identifier_type":"HDL","subitem_identifier_uri":"http://hdl.handle.net/2241/118868"}]},"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.87.034509","subitem_relation_type_select":"DOI"}}]},"item_5_rights_12":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"(c) 2013 American Physical Society","subitem_rights_language":"en"}]},"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":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AA00773624","subitem_source_identifier_type":"NCID"}]},"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":"Ohki, H.","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Takeda, K.","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Aoki, S.","creatorNameLang":"en"},{"creatorName":"青木, 愼也","creatorNameLang":"ja"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Hashimoto, S.","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Kaneko, T.","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Matsufuru, H.","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Noaki, J.","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Onogi, T.","creatorNameLang":"en"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2013-12-25"}],"displaytype":"detail","filename":"PRD_87-3.pdf","filesize":[{"value":"503.9 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"PRD_87-3.pdf","objectType":"fulltext","url":"https://tsukuba.repo.nii.ac.jp/record/28702/files/PRD_87-3.pdf"},"version_id":"ee3d2eda-9844-4e00-a899-8f96db52f3bd"}]},"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":"Nucleon strange quark content from N_f=2+1 lattice QCD with exact chiral symmetry","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Nucleon strange quark content from N_f=2+1 lattice QCD with exact chiral symmetry","subitem_title_language":"en"}]},"item_type_id":"5","owner":"1","path":["84","294"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2013-04-17"},"publish_date":"2013-04-17","publish_status":"0","recid":"28702","relation_version_is_last":true,"title":["Nucleon strange quark content from N_f=2+1 lattice QCD with exact chiral symmetry"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2022-08-23T06:48:55.993634+00:00"}
