We use D+→K?π+π+ decays fully reconstructed in the central rapidity region |y|<1 with transverse momentum down to 1.5??GeV/c, a range previously unexplored in p￣p collisions. Inelastic p￣p-scattering events are selected online using minimally biasing requirements followed by an optimized offline selection. The K?π+π+ mass distribution is used to identify the D+ signal, and the D+ transverse impact-parameter distribution is used to separate prompt production, occurring directly in the hard-scattering process, from secondary production from b-hadron decays. We obtain a prompt D+ signal of 2950 candidates corresponding to a total cross section σ(D+,1.5<pT<14.5??GeV/c,|y|<1)=71.9±6.8(stat)±9.3(syst)??μb. While the measured cross sections are consistent with theoretical estimates in each pT bin, the shape of the observed pT spectrum is softer than the expectation from quantum chromodynamics. The results are unique in p￣p collisions and can improve the shape and uncertainties of future predictions.","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.95.092006","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":"CD Collaboration","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Hara, K.","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Kim, S.H.","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Sato, K.","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Ukegawa, F.","creatorNameLang":"en"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2017-07-04"}],"displaytype":"detail","filename":"PRD_95-9-092006.pdf","filesize":[{"value":"916.0 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"PRD_95-9-092006","objectType":"fulltext","url":"https://tsukuba.repo.nii.ac.jp/record/41764/files/PRD_95-9-092006.pdf"},"version_id":"6ce5647b-e0a9-4f59-bfb8-7eab6b341d42"}]},"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":"Measurement of the D+-meson production cross section at low transverse momentum in p￣p collisions at √s=1.96??TeV","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Measurement of the D+-meson production cross section at low transverse momentum in p￣p collisions at √s=1.96??TeV","subitem_title_language":"en"}]},"item_type_id":"5","owner":"1","path":["790","1206","5006","789","84"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2017-07-04"},"publish_date":"2017-07-04","publish_status":"0","recid":"41764","relation_version_is_last":true,"title":["Measurement of the D+-meson production cross section at low transverse momentum in p￣p collisions at √s=1.96??TeV"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-12-21T07:58:46.271682+00:00"}
