But we found we need more and more terms when we go to larger beta.\n2)The difference of timelike and spacelike monopole currents is shown to be a good order parameter of finite-temperature full SU(2) QCD.\n1993 : 1) Efective U(1) action is determined compactly in terms of monopole currents using Swendsen's method. We found monopole condensation is shwon to happen also in the confinement phase of SU(2) QCD.\n2)The string tension is reproduced by monopole contribution alone and the Coulomb term is from photons alone after the abelian projection in the maximally abelian gauge.\n3)The confinement vacuum is studied evaluating correlations between a Wilson loop and monopole currents and another Wilson loop. The vacuum is seen to be around the border between type-1 and type-2 super (magnetic) conductor.\n(Analytic study of infrared effective QCD)\n1992 : The analysis is extended to the static baryon case. We got the potential for the general configuration of the three quarks. It is approximately determined by the linear length of the strings between the sources.\n1993 : We evaluated spin and velocity dependent baryon potential in the simplest configuration case.","subitem_description_type":"Abstract"}]},"item_10007_description_14":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"研究課題/領域番号:04640289, 研究期間(年度):1992-1993","subitem_description_type":"Other"},{"subitem_description":"研究機関: 金沢大学理学部","subitem_description_type":"Other"},{"subitem_description":"出典：「モンテ・カルロ法を使ったQCDでのクォーク閉じ込め機構の研究」研究成果報告書　課題番号04640289\n(KAKEN：科学研究費助成事業データベース（国立情報学研究所）)\n　　　本文データは著者版報告書より作成","subitem_description_type":"Other"}]},"item_10007_description_4":{"attribute_name":"研究代表者ID","attribute_value_mlt":[{"subitem_description":"60019502","subitem_description_type":"Other"}]},"item_10007_description_9":{"attribute_name":"研究課題番号","attribute_value_mlt":[{"subitem_description":"04640289","subitem_description_type":"Other"}]},"item_10007_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.24517/00048855","subitem_identifier_reg_type":"JaLC"}]},"item_10007_relation_17":{"attribute_name":"関連サイト","attribute_value_mlt":[{"subitem_relation_name":[{"subitem_relation_name_text":"https://kaken.nii.ac.jp/search/?qm=60019502"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://kaken.nii.ac.jp/search/?qm=60019502","subitem_relation_type_select":"URI"}},{"subitem_relation_name":[{"subitem_relation_name_text":"https://kaken.nii.ac.jp/grant/KAKENHI-PROJECT-04640289/"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://kaken.nii.ac.jp/grant/KAKENHI-PROJECT-04640289/","subitem_relation_type_select":"URI"}},{"subitem_relation_name":[{"subitem_relation_name_text":"https://kaken.nii.ac.jp/report/KAKENHI-PROJECT-04640289/046402891993kenkyu_seika_hokoku_gaiyo/"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://kaken.nii.ac.jp/report/KAKENHI-PROJECT-04640289/046402891993kenkyu_seika_hokoku_gaiyo/","subitem_relation_type_select":"URI"}}]},"item_10007_version_type_20":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_ab4af688f83e57aa","subitem_version_type":"AM"}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2017-11-13"}],"displaytype":"detail","filename":"SC-PR-SUZUKI-T-kaken 1994-18p.pdf","filesize":[{"value":"559.2 kB"}],"format":"application/pdf","licensetype":"license_11","mimetype":"application/pdf","url":{"label":"SC-PR-SUZUKI-T-kaken 1994-18p.pdf","url":"https://kanazawa-u.repo.nii.ac.jp/record/42500/files/SC-PR-SUZUKI-T-kaken 1994-18p.pdf"},"version_id":"191b712a-832b-4c98-9660-0c2ce6ecd8fe"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Quark confinement","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Monopole","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Monte-Carlo Simulation","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Lattice QCD","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Dual transformation","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Infrared effective theory of QCD","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Finite-temperature phase transition","subitem_subject_language":"en","subitem_subject_scheme":"Other"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"jpn"}]},"item_researcher":{"attribute_name":"研究代表者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"鈴木, 恒雄"}],"nameIdentifiers":[{"nameIdentifier":"67535","nameIdentifierScheme":"WEKO"},{"nameIdentifier":"60019502","nameIdentifierScheme":"e-Rad","nameIdentifierURI":"https://kaken.nii.ac.jp/ja/search/?qm=60019502"}]},{"creatorNames":[{"creatorName":"Suzuki, Tsuneo"}],"nameIdentifiers":[{"nameIdentifier":"67536","nameIdentifierScheme":"WEKO"}]}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"research report","resourceuri":"http://purl.org/coar/resource_type/c_18ws"}]},"item_title":"モンテ・カルロ法を使ったQCDでのクォーク閉じ込め機構の研究","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"モンテ・カルロ法を使ったQCDでのクォーク閉じ込め機構の研究"},{"subitem_title":"Monte-Carlo Study of Quark Confinement in QCD","subitem_title_language":"en"}]},"item_type_id":"10007","owner":"18","path":["2840"],"pubdate":{"attribute_name":"公開日","attribute_value":"2017-11-13"},"publish_date":"2017-11-13","publish_status":"0","recid":"42500","relation_version_is_last":true,"title":["モンテ・カルロ法を使ったQCDでのクォーク閉じ込め機構の研究"],"weko_creator_id":"18","weko_shared_id":-1},"updated":"2023-07-27T11:49:29.699330+00:00"}
