The data analyzed were taken during √s=510 GeV longitudinally polarized p+p collisions at the Relativistic Heavy Ion Collider in the 2013 run using the PHENIX detector. At this collision energy, J/ψ particles are predominantly produced through gluon-gluon scatterings, thus AJ/ψLL is sensitive to the gluon polarization inside the proton. We measured AJ/ψLL by detecting the decay daughter muon pairs μ+μ- within the PHENIX muon spectrometers in the rapidity range 1.2<|y|<2.2. In this kinematic range, we measured the AJ/ψLL to be 0.012±0.010 (stat) ±0.003 (syst). The AJ/ψLL can be expressed to be proportional to the product of the gluon polarization distributions at two distinct ranges of Bjorken x: one at moderate range x≈5×10^-2 where recent data of jet and π^0 double helicity spin asymmetries have shown evidence for significant gluon polarization, and the other one covering the poorly known small-x region x≈2×10^-3. Thus our new results could be used to further constrain the gluon polarization for x<5×10^-2.","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_10":{"attribute_name":"PubMed番号","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"25170701","subitem_relation_type_select":"PMID"}}]},"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.94.112008","subitem_relation_type_select":"DOI"}}]},"item_5_rights_12":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"(c) 2016 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"}],"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":"2017-02-27"}],"displaytype":"detail","filename":"PRD_94-11.pdf","filesize":[{"value":"413.8 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"PRD_94-11","objectType":"fulltext","url":"https://tsukuba.repo.nii.ac.jp/record/40368/files/PRD_94-11.pdf"},"version_id":"386d79b9-04ba-4e9b-a0e8-4590cd29bd1d"}]},"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 double-helicity asymmetries in inclusive J／ψ production in longitudinally polarized p+p collisions at √s=510 GeV","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Measurements of double-helicity asymmetries in inclusive J／ψ production in longitudinally polarized 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":"2017-02-27"},"publish_date":"2017-02-27","publish_status":"0","recid":"40368","relation_version_is_last":true,"title":["Measurements of double-helicity asymmetries in inclusive J／ψ production in longitudinally polarized p+p collisions at √s=510 GeV"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2022-08-02T01:17:10.542699+00:00"}
