These mesons are introduced as chiral partners in the chiralsymmetry-broken vacuum, hence they are useful to explore the partial restoration of the broken chiral symmetry in nuclear matter. We consider the linear sigma model to describe the chiral symmetry breaking and to investigatea qualitative tendency of changes of D^¯mesons at low density. Our study shows that the loop corrections to D and D^¯^∗ 0 meson masses provide a smaller mass splitting at finite density than that in vacuum, a result that indicates a tendency of the restoration of the chiral symmetry. We investigate also the spectral function for D^¯^∗0 meson channel, and find three peaks. The first peak, which corresponds to the resonance of the D^¯^∗ 0 meson, is broadened by collisions with nucleons in medium, and the peak position shifts to lower mass due to the partial restoration of chiral symmetry as the density increases. The second peak is identified as a threshold enhancement which shows a remarkable enhancement as the density increases. The third peak is Landau damping. The obtained properties of D^¯and D^¯^∗ 0 mesons in nuclear matter will provide useful information for experiments.", "subitem_description_language": "en", "subitem_description_type": "Abstract"}]}, "item_10_identifier_60": {"attribute_name": "URI", "attribute_value_mlt": [{"subitem_identifier_type": "DOI", "subitem_identifier_uri": "http://doi.org/10.1103/PhysRevC.96.015204"}, {"subitem_identifier_type": "HDL", "subitem_identifier_uri": "http://hdl.handle.net/2237/27022"}]}, "item_10_publisher_32": {"attribute_name": "出版者", "attribute_value_mlt": [{"subitem_publisher": "American Physical Society", "subitem_publisher_language": "en"}]}, "item_10_relation_11": {"attribute_name": "DOI", "attribute_value_mlt": [{"subitem_relation_type": "isVersionOf", "subitem_relation_type_id": {"subitem_relation_type_id_text": "https://doi.org/10.1103/PhysRevC.96.015204", "subitem_relation_type_select": "DOI"}}]}, "item_10_rights_12": {"attribute_name": "権利", "attribute_value_mlt": [{"subitem_rights": "© 2017 American Physical Society", "subitem_rights_language": "en"}]}, "item_10_select_15": {"attribute_name": "著者版フラグ", "attribute_value_mlt": [{"subitem_select_item": "publisher"}]}, "item_10_source_id_7": {"attribute_name": "ISSN", "attribute_value_mlt": [{"subitem_source_identifier": "2469-9985", "subitem_source_identifier_type": "PISSN"}]}, "item_1615787544753": {"attribute_name": "出版タイプ", "attribute_value_mlt": [{"subitem_version_resource": "http://purl.org/coar/version/c_970fb48d4fbd8a85", "subitem_version_type": "VoR"}]}, "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": "Suenaga, Daiki", "creatorNameLang": "en"}], "nameIdentifiers": [{"nameIdentifier": "73745", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Yasui, Shigehiro", "creatorNameLang": "en"}], "nameIdentifiers": [{"nameIdentifier": "73746", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Harada, Masayasu", "creatorNameLang": "en"}], "nameIdentifiers": [{"nameIdentifier": "73747", "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": "2018-02-22"}], "displaytype": "detail", "download_preview_message": "", "file_order": 0, "filename": "PhysRevC_96_015204.pdf", "filesize": [{"value": "1.3 MB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_note", "mimetype": "application/pdf", "size": 1300000.0, "url": {"label": "PhysRevC_96_015204.pdf", "objectType": "fulltext", "url": "https://nagoya.repo.nii.ac.jp/record/24800/files/PhysRevC_96_015204.pdf"}, "version_id": "a85d862c-ba6c-4114-837a-dec1690b0ede"}]}, "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": "Spectral functions for D^¯and D^¯^∗0 mesons in nuclear matter with partial restoration of chiral symmetry", "item_titles": {"attribute_name": "タイトル", "attribute_value_mlt": [{"subitem_title": "Spectral functions for D^¯and D^¯^∗0 mesons in nuclear matter with partial restoration of chiral symmetry", "subitem_title_language": "en"}]}, "item_type_id": "10", "owner": "1", "path": ["696"], "permalink_uri": "http://hdl.handle.net/2237/27022", "pubdate": {"attribute_name": "PubDate", "attribute_value": "2017-10-06"}, "publish_date": "2017-10-06", "publish_status": "0", "recid": "24800", "relation": {}, "relation_version_is_last": true, "title": ["Spectral functions for D^¯and D^¯^∗0 mesons in nuclear matter with partial restoration of chiral symmetry"], "weko_shared_id": -1}
