We use these series in μ q /T to determine lines of constant entropy per baryon number (S/N B ) that characterize the expansion of dense matter created in heavy ion collisions. In the high temperature regime these lines are found to be well approximated by lines of constant μ q /T . In the low temperature phase, however, the quark chemical potential is found to increase with decreasing temperature. This is in accordance with resonance gas model calculations. Along the lines of constant S/N B we calculate the energy density and pressure. Within the accuracy of our present analysis we find that the ratio p/ϵ for T\u003eT 0 as well as the softest point of the equation of state, (p/ϵ) min ≃0.075 , show no significant dependence on S/N B.", "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.73.054506", "subitem_relation_type_select": "DOI"}}]}, "item_5_rights_15": {"attribute_name": "権利", "attribute_value_mlt": [{"subitem_rights": "(C) 2006 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": "Ejiri, S."}], "nameIdentifiers": [{"nameIdentifier": "11008", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Karsch, F."}], "nameIdentifiers": [{"nameIdentifier": "11009", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Laermann, E."}], "nameIdentifiers": [{"nameIdentifier": "11010", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Schmidt, C."}], "nameIdentifiers": [{"nameIdentifier": "11011", "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": "73_5_054506.pdf", "filesize": [{"value": "246.0 kB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_free", "mimetype": "application/pdf", "size": 246000.0, "url": {"label": "73_5_054506.pdf", "url": "https://niigata-u.repo.nii.ac.jp/record/2302/files/73_5_054506.pdf"}, "version_id": "0a9f2352-d23a-4dcd-90a9-ab91d9847f9e"}]}, "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": "Isentropic equation of state of 2-flavor QCD", "item_titles": {"attribute_name": "タイトル", "attribute_value_mlt": [{"subitem_title": "Isentropic equation of state of 2-flavor QCD"}, {"subitem_title": "Isentropic equation of state of 2-flavor QCD", "subitem_title_language": "en"}]}, "item_type_id": "5", "owner": "1", "path": ["454", "489"], "permalink_uri": "http://hdl.handle.net/10191/27667", "pubdate": {"attribute_name": "公開日", "attribute_value": "2014-06-23"}, "publish_date": "2014-06-23", "publish_status": "0", "recid": "2302", "relation": {}, "relation_version_is_last": true, "title": ["Isentropic equation of state of 2-flavor QCD"], "weko_shared_id": null}
