The measurement is performed using the forward silicon vertex detector and central vertex detector at PHENIX, which provide precise tracking and distance-of-closest-approach determinations, enabling the statistical separation of J/ψ due to B-meson decays from prompt J/ψ. The measured value of FB→J/ψ is 8.1%±2.3%(stat)±1.9%(syst) for J/ψ with transverse momenta 0<pT<5 GeV/c and rapidity 1.2<|y|<2.2. The measured fraction FB→J/ψ at PHENIX is compared to values measured by other experiments at higher center of mass energies and to fixed-order-next-to-leading-logarithm and color-evaporation-model predictions. The b￣b cross section per unit rapidity [dσ/dy(pp→b￣b)] extracted from the obtained FB→J/ψ and the PHENIX inclusive J/ψ cross section measured at 200 GeV scaled with color-evaporation-model calculations, at the mean B hadron rapidity y=±1.7 in 510 GeV p+p collisions, is 3.63_(-1.70)^(+1.92) μb. It is consistent with the fixed-order-next-to-leading-logarithm calculations.","subitem_description_language":"en","subitem_description_type":"Abstract"}]},"item_5_publisher_27":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"American Physical Society","subitem_publisher_language":"en"}]},"item_5_relation_11":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type":"isIdenticalTo","subitem_relation_type_id":{"subitem_relation_type_id_text":"https://doi.org/10.1103/PhysRevD.95.092002","subitem_relation_type_select":"DOI"}}]},"item_5_rights_12":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"(c) 2017 American Physical Society","subitem_rights_language":"en"}]},"item_5_source_id_7":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"2470-0010","subitem_source_identifier_type":"PISSN"}]},"item_5_source_id_9":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AA00773624","subitem_source_identifier_type":"NCID"}]},"item_access_right":{"attribute_name":"アクセス権","attribute_value_mlt":[{"subitem_access_right":"open access","subitem_access_right_uri":"http://purl.org/coar/access_right/c_abf2"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"PHENI Collaboration","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Chujo, T.","creatorNameLang":"en"},{"creatorName":"中條, 達也","creatorNameLang":"ja"},{"creatorName":"チュウジョウ, タツヤ","creatorNameLang":"ja-Kana"}],"nameIdentifiers":[{},{},{}]},{"creatorNames":[{"creatorName":"Esumi, S.","creatorNameLang":"en"},{"creatorName":"江角, 晋一","creatorNameLang":"ja"},{"creatorName":"エスミ, シンイチ","creatorNameLang":"ja-Kana"}],"nameIdentifiers":[{},{},{}]},{"creatorNames":[{"creatorName":"Miake, Y.","creatorNameLang":"en"},{"creatorName":"三明, 康郎","creatorNameLang":"ja"},{"creatorName":"ミアケ, ヤスオ","creatorNameLang":"ja-Kana"}],"nameIdentifiers":[{},{},{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2017-06-07"}],"displaytype":"detail","filename":"PRD_95-092002.pdf","filesize":[{"value":"1.5 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"PRD_95-9-92002","objectType":"fulltext","url":"https://tsukuba.repo.nii.ac.jp/record/41461/files/PRD_95-092002.pdf"},"version_id":"172a5f43-2168-4803-9c8a-7793e11d9e34"}]},"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":"Measurements of B→J/ψ at forward rapidity in p+p collisions at √s=510 GeV","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Measurements of B→J/ψ at forward rapidity in p+p collisions at √s=510 GeV","subitem_title_language":"en"}]},"item_type_id":"5","owner":"1","path":["84","3072","5003","5004"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2017-06-07"},"publish_date":"2017-06-07","publish_status":"0","recid":"41461","relation_version_is_last":true,"title":["Measurements of B→J/ψ at forward rapidity in p+p collisions at √s=510 GeV"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2022-08-01T05:52:52.955042+00:00"}
