These mesons are introduced as chiral partners in the chiralsymmetry-broken\nvacuum, hence they are useful to explore the partial restoration of the broken chiral symmetry\nin nuclear matter. We consider the linear sigma model to describe the chiral symmetry breaking and to investigatea qualitative tendency of changes of D^\u00afmesons at low density. Our study shows that the loop corrections to D and D^\u00af^\u2217\n0 meson masses provide a smaller mass splitting at finite density than that in vacuum, a result that indicates\na tendency of the restoration of the chiral symmetry. We investigate also the spectral function for D^\u00af^\u22170 meson channel, and find three peaks. The first peak, which corresponds to the resonance of the D^\u00af^\u2217\n0 meson, is broadened\nby collisions with nucleons in medium, and the peak position shifts to lower mass due to the partial restoration of\nchiral symmetry as the density increases. The second peak is identified as a threshold enhancement which shows\na remarkable enhancement as the density increases. The third peak is Landau damping. The obtained properties of D^\u00afand D^\u00af^\u2217\n0 mesons in nuclear matter will provide useful information for experiments.", "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": "\u51fa\u7248\u8005", "attribute_value_mlt": [{"subitem_publisher": "American Physical Society"}]}, "item_10_rights_12": {"attribute_name": "\u6a29\u5229", "attribute_value_mlt": [{"subitem_rights": "\u00a9 2017 American Physical Society"}]}, "item_10_select_15": {"attribute_name": "\u8457\u8005\u7248\u30d5\u30e9\u30b0", "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": "ISSN"}]}, "item_creator": {"attribute_name": "\u8457\u8005", "attribute_type": "creator", "attribute_value_mlt": [{"creatorNames": [{"creatorName": "Suenaga, Daiki"}], "nameIdentifiers": [{"nameIdentifier": "73745", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Yasui, Shigehiro"}], "nameIdentifiers": [{"nameIdentifier": "73746", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Harada, Masayasu"}], "nameIdentifiers": [{"nameIdentifier": "73747", "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": "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_free", "mimetype": "application/pdf", "size": 1300000.0, "url": {"label": "PhysRevC_96_015204.pdf", "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": "\u8a00\u8a9e", "attribute_value_mlt": [{"subitem_language": "eng"}]}, "item_resource_type": {"attribute_name": "\u8cc7\u6e90\u30bf\u30a4\u30d7", "attribute_value_mlt": [{"resourcetype": "journal article", "resourceuri": "http://purl.org/coar/resource_type/c_6501"}]}, "item_title": "Spectral functions for D^\u00afand D^\u00af^\u22170 mesons in nuclear matter with partial restoration of chiral symmetry", "item_titles": {"attribute_name": "\u30bf\u30a4\u30c8\u30eb", "attribute_value_mlt": [{"subitem_title": "Spectral functions for D^\u00afand D^\u00af^\u22170 mesons in nuclear matter with partial restoration of chiral symmetry"}]}, "item_type_id": "10", "owner": "1", "path": ["336/695/696"], "permalink_uri": "http://hdl.handle.net/2237/27022", "pubdate": {"attribute_name": "\u516c\u958b\u65e5", "attribute_name_i18n": "\u516c\u958b\u65e5", "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^\u00afand D^\u00af^\u22170 mesons in nuclear matter with partial restoration of chiral symmetry"], "weko_shared_id": null}
