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>T 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","filename":"73_5_054506.pdf","filesize":[{"value":"246.0 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","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"],"pubdate":{"attribute_name":"公開日","attribute_value":"2014-06-23"},"publish_date":"2014-06-23","publish_status":"0","recid":"2302","relation_version_is_last":true,"title":["Isentropic equation of state of 2-flavor QCD"],"weko_creator_id":"1","weko_shared_id":null},"updated":"2022-12-15T03:35:13.432954+00:00"}
