From this, we have derived n¯b-n¯uds=3.31±0.41±0.79. Comparing this measurement with those at lower center-of-mass energies, we find no evidence that n¯b-n¯uds depends on energy. This result is in agreement with a precise prediction of perturbative QCD, and supports the notion that QCD remains asymptotically free down to the scale Mb2.","subitem_description_language":"en"}]},"item_1617186643794":{"attribute_name":"Publisher","attribute_value_mlt":[{"subitem_publisher":"American Physical Society"}]},"item_1617186702042":{"attribute_name":"Language","attribute_value_mlt":[{"subitem_language":"eng"}]},"item_1617186920753":{"attribute_name":"Source Identifier","attribute_value_mlt":[{"subitem_source_identifier":"0031-9007","subitem_source_identifier_type":"ISSN"},{"subitem_source_identifier":"AA00773679","subitem_source_identifier_type":"NCID"}]},"item_1617187024783":{"attribute_name":"Page Start","attribute_value_mlt":[{"subitem_start_page":"3145"}]},"item_1617187056579":{"attribute_name":"Bibliographic Information","attribute_value_mlt":[{"bibliographicIssueDates":{"bibliographicIssueDate":"1994-05-16","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"20","bibliographicPageEnd":"3149","bibliographicPageStart":"3145","bibliographicVolumeNumber":"72","bibliographic_titles":[{"bibliographic_title":"Physical Review Letters"},{"bibliographic_title":"Physical Review Letters"}]}]},"item_1617258105262":{"attribute_name":"Resource Type","attribute_value_mlt":[{"resourcetype":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_1617265215918":{"attribute_name":"Version Type","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"item_1617353299429":{"attribute_name":"Relation","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"10.1103/PhysRevLett.72.3145","subitem_relation_type_select":"DOI"}},{"subitem_relation_type_id":{"subitem_relation_type_id_text":"http://dx.doi.org/10.1103/PhysRevLett.72.3145","subitem_relation_type_select":"DOI"}}]},"item_1617605131499":{"attribute_name":"File","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_access","date":[{"dateType":"Available","dateValue":"2023-03-18"}],"displaytype":"simple","filename":"PhysRevLett_72_3145.pdf","filesize":[{"value":"868.0 KB"}],"mimetype":"application/pdf","url":{"objectType":"fulltext","url":"https://hiroshima.repo.nii.ac.jp/record/2008470/files/PhysRevLett_72_3145.pdf"},"version_id":"0383d802-afaf-487a-8e4a-0eccf82c6f06"}]},"item_1732771732025":{"attribute_name":"旧ID","attribute_value":"18761"},"item_title":"Measurement of the Charged Multiplicity of Z0→bb¯ Events","item_type_id":"40003","owner":"41","path":["1730444907710"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2023-03-18"},"publish_date":"2023-03-18","publish_status":"0","recid":"2008470","relation_version_is_last":true,"title":["Measurement of the Charged Multiplicity of Z0→bb¯ Events"],"weko_creator_id":"41","weko_shared_id":-1},"updated":"2025-02-22T03:46:45.150307+00:00"}
