The heavy quark mass dependence is explicitly studied over a mass range between mb and 4mb with the O(1/mQ) and O(1/mQ2) actions. We find that the ratios of lattice matrix elements 〈ONlat〉/〈A0lat〉2 and 〈OSlat〉/〈A0lat〉2, which contribute to BB through mixing, have significant 1/mQ dependence while that of the leading operator 〈OLlat〉/〈A0lat〉2 has little 1/mQ effect. The combined result for BB(mb) has small but nonzero mass dependence, and the BB(mb) becomes smaller by 10% with the 1/mQ correction compared to the static result. Our result in the quenched approximation at β=5.9 is BBd(5 GeV) = 0.75(3)(12), where the first error is statistical and the second is a systematic uncertainty.","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":"1550-7998","subitem_source_identifier_type":"ISSN"},{"subitem_source_identifier":"AA00773624","subitem_source_identifier_type":"NCID"}]},"item_1617187024783":{"attribute_name":"Page Start","attribute_value_mlt":[{"subitem_start_page":"094503-1"}]},"item_1617187056579":{"attribute_name":"Bibliographic Information","attribute_value_mlt":[{"bibliographicIssueDates":{"bibliographicIssueDate":"1999-09-27","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"9","bibliographicPageEnd":"094503-10","bibliographicPageStart":"094503-1","bibliographicVolumeNumber":"60","bibliographic_titles":[{"bibliographic_title":"Physical Review D"},{"bibliographic_title":"Physical Review D"}]}]},"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/PhysRevD.60.094503","subitem_relation_type_select":"DOI"}},{"subitem_relation_type_id":{"subitem_relation_type_id_text":"http://dx.doi.org/10.1103/PhysRevD.60.094503","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":"PhysRevD_60_094503.pdf","filesize":[{"value":"143.1 KB"}],"mimetype":"application/pdf","url":{"objectType":"fulltext","url":"https://hiroshima.repo.nii.ac.jp/record/2008340/files/PhysRevD_60_094503.pdf"},"version_id":"bf3c7517-046d-4ed3-b964-4eff31402706"}]},"item_1732771732025":{"attribute_name":"旧ID","attribute_value":"19258"},"item_title":"Lattice NRQCD calculation of the B0-B̅0 mixing parameter BB","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":"2008340","relation_version_is_last":true,"title":["Lattice NRQCD calculation of the B0-B̅0 mixing parameter BB"],"weko_creator_id":"41","weko_shared_id":-1},"updated":"2025-02-22T03:33:43.495566+00:00"}
