We study also tetra-quark and penta-quark potentials in lattice QCD, and find that they are well described by the OGE Coulomb plus multi-Y type linear potential, which supports the flux-tube picture even for multi-quarks. Finally, narrow decay width of low-lying penta-quark baryons is discussed in terms of the QCD string theory.", "subitem_description_type": "Abstract"}]}, "item_8_full_name_3": {"attribute_name": "\u8457\u8005\u5225\u540d", "attribute_value_mlt": [{"nameIdentifiers": [{"nameIdentifier": "168703", "nameIdentifierScheme": "WEKO"}], "names": [{"name": "\u8208\u6cbb, \u6587\u5b50"}]}, {"nameIdentifiers": [{"nameIdentifier": "168704", "nameIdentifierScheme": "WEKO"}], "names": [{"name": "Okiharu, Fumiko"}]}]}, "item_8_publisher_7": {"attribute_name": "\u51fa\u7248\u8005", "attribute_value_mlt": [{"subitem_publisher": "American Institute of Physics"}]}, "item_8_relation_14": {"attribute_name": "DOI", "attribute_value_mlt": [{"subitem_relation_type_id": {"subitem_relation_type_id_text": "info:doi/10.1063/1.1920939", "subitem_relation_type_select": "DOI"}}]}, "item_8_rights_15": {"attribute_name": "\u6a29\u5229", "attribute_value_mlt": [{"subitem_rights": "Copyright(C)2005 American Institute of Physics"}]}, "item_8_select_19": {"attribute_name": "\u8457\u8005\u7248\u30d5\u30e9\u30b0", "attribute_value_mlt": [{"subitem_select_item": "publisher"}]}, "item_8_source_id_11": {"attribute_name": "\u66f8\u8a8c\u30ec\u30b3\u30fc\u30c9ID", "attribute_value_mlt": [{"subitem_source_identifier": "AA00502977", "subitem_source_identifier_type": "NCID"}]}, "item_8_source_id_9": {"attribute_name": "ISSN", "attribute_value_mlt": [{"subitem_source_identifier": "0094243X", "subitem_source_identifier_type": "ISSN"}]}, "item_creator": {"attribute_name": "\u8457\u8005", "attribute_type": "creator", "attribute_value_mlt": [{"creatorNames": [{"creatorName": "Suganuma, H."}], "nameIdentifiers": [{"nameIdentifier": "168699", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Takahashi, T.T."}], "nameIdentifiers": [{"nameIdentifier": "168700", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Okiharu, F."}], "nameIdentifiers": [{"nameIdentifier": "168701", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Ichie, H."}], "nameIdentifiers": [{"nameIdentifier": "168702", "nameIdentifierScheme": "WEKO"}]}]}, "item_files": {"attribute_name": "\u30d5\u30a1\u30a4\u30eb\u60c5\u5831", "attribute_type": "file", "attribute_value_mlt": [{"accessrole": "open_date", "date": [{"dateType": "Available", "dateValue": "2019-08-26"}], "displaytype": "detail", "download_preview_message": "", "file_order": 0, "filename": "756_1_123-132.pdf", "filesize": [{"value": "449.4 kB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_free", "mimetype": "application/pdf", "size": 449400.0, "url": {"label": "756_1_123-132.pdf", "url": "https://niigata-u.repo.nii.ac.jp/record/30879/files/756_1_123-132.pdf"}, "version_id": "803eb4ca-81a0-4eb5-a64a-c8d872c73e4b"}]}, "item_keyword": {"attribute_name": "\u30ad\u30fc\u30ef\u30fc\u30c9", "attribute_value_mlt": [{"subitem_subject": "lattice QCD", "subitem_subject_scheme": "Other"}, {"subitem_subject": "inter-quark potential", "subitem_subject_scheme": "Other"}, {"subitem_subject": "multi-quark", "subitem_subject_scheme": "Other"}, {"subitem_subject": "gluonic excitation", "subitem_subject_scheme": "Other"}, {"subitem_subject": "confinement", "subitem_subject_scheme": "Other"}, {"subitem_subject": "string", "subitem_subject_scheme": "Other"}]}, "item_language": {"attribute_name": "\u8a00\u8a9e", "attribute_value_mlt": [{"subitem_language": "eng"}]}, "item_resource_type": {"attribute_name": "\u8cc7\u6e90\u30bf\u30a4\u30d7", "attribute_value_mlt": [{"resourcetype": "conference paper", "resourceuri": "http://purl.org/coar/resource_type/c_5794"}]}, "item_title": "Lattice QCD Study for the Interquark Force in Three-Quark and Multi-Quark Systems", "item_titles": {"attribute_name": "\u30bf\u30a4\u30c8\u30eb", "attribute_value_mlt": [{"subitem_title": "Lattice QCD Study for the Interquark Force in Three-Quark and Multi-Quark Systems"}, {"subitem_title": "Lattice QCD Study for the Interquark Force in Three-Quark and Multi-Quark Systems", "subitem_title_language": "en"}]}, "item_type_id": "8", "owner": "1", "path": ["453/457", "154/1815/1816"], "permalink_uri": "http://hdl.handle.net/10191/30873", "pubdate": {"attribute_name": "\u516c\u958b\u65e5", "attribute_value": "2014-12-05"}, "publish_date": "2014-12-05", "publish_status": "0", "recid": "30879", "relation": {}, "relation_version_is_last": true, "title": ["Lattice QCD Study for the Interquark Force in Three-Quark and Multi-Quark Systems"], "weko_shared_id": null}
