The standard Wilson action at β= 5.75 and the O (a) improved Wilson quark action with k = 0.1210(0.0010)0.1240 are employed on a 12^3 × 96 lattice. Contribution of excited states is suppressed by using a smeared source. We investigate both the positive- and negative-parity 5Q baryons with I = 0 and spin J = 1/2 using a non-NK-type interpolating field. After chiral extrapolation, the lowest positive-parity state is found to have a mass, m_\u003c5Q\u003e = 2.25 GeV, which is much heavier than the experimentally observed Θ^+ (1540). The lowest negative-parity 5Q state appears at m_\u003c5Q\u003e = 1.75 GeV, which is near the s-wave NK threshold. To distinguish spatially-localized 5Q resonances from NK-scattering states, we propose a new general method imposing a ‘‘Hybrid Boundary Condition (HBC),’’ where the NK threshold is artificially raised without affecting compact five-quark states. The study using the HBC method shows that the negative-parity state observed on the lattice is not a compact 5Q state but an s-wave NK-scattering state.", "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.71.034001", "subitem_relation_type_select": "DOI"}}]}, "item_5_rights_15": {"attribute_name": "権利", "attribute_value_mlt": [{"subitem_rights": "Copyright: The 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": "Ishii, N."}], "nameIdentifiers": [{"nameIdentifier": "14302", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Doi, T."}], "nameIdentifiers": [{"nameIdentifier": "14303", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Iida, H."}], "nameIdentifiers": [{"nameIdentifier": "14304", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Oka, M."}], "nameIdentifiers": [{"nameIdentifier": "14305", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Okiharu, F."}], "nameIdentifiers": [{"nameIdentifier": "14306", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Suganuma, H."}], "nameIdentifiers": [{"nameIdentifier": "14307", "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", "download_preview_message": "", "file_order": 0, "filename": "034001.pdf", "filesize": [{"value": "191.9 kB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_free", "mimetype": "application/pdf", "size": 191900.0, "url": {"label": "034001.pdf", "url": "https://niigata-u.repo.nii.ac.jp/record/2327/files/034001.pdf"}, "version_id": "174c3f52-fcb7-43fa-96fc-82075126ece7"}]}, "item_keyword": {"attribute_name": "キーワード", "attribute_value_mlt": [{"subitem_subject": "Okiharu, Fumiko", "subitem_subject_scheme": "Other"}, {"subitem_subject": "興治, 文子", "subitem_subject_scheme": "Other"}]}, "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": "Pentaquark baryon in anisotropic lattice QCD", "item_titles": {"attribute_name": "タイトル", "attribute_value_mlt": [{"subitem_title": "Pentaquark baryon in anisotropic lattice QCD"}, {"subitem_title": "Pentaquark baryon in anisotropic lattice QCD", "subitem_title_language": "en"}]}, "item_type_id": "5", "owner": "1", "path": ["454", "502"], "permalink_uri": "http://hdl.handle.net/10191/24843", "pubdate": {"attribute_name": "公開日", "attribute_value": "2014-01-28"}, "publish_date": "2014-01-28", "publish_status": "0", "recid": "2327", "relation": {}, "relation_version_is_last": true, "title": ["Pentaquark baryon in anisotropic lattice QCD"], "weko_shared_id": null}
