The data corresponds to 275 milion BB meson from B+　→　J/k*+ and the K*+ decay into K*+ →K+π0 and Ksπ+ sub-decay modes. The complex decay amplitudes of three helicity final states of B+ →　J/K*+(Ksπ+) are measured by a simulataneous fit to three transversity angles. We have extacted decay amplitudes by full anfular analysis with an improved un-binned maximum likehood fit method. We have determined absolute values of three decay amplitudes and two relative phase reporded in neutral B0→ J/K*+. The breakdown existence in charged B+ →J/K*+ is measured 1.59o. We compared with the decay amplitutes between neutral and charged B → J/K* system. The measured amplitudes between charged plus and minus are consistent within the errors except for B± → J/K*±(K*+ → Ksπ±). The difference is measured 2.39o in opposite charge sign. With the decay amplitudes measured in charged B+ → J/K*+, we extract the triple product correlation parameter which has a sensitivity to the R-party violating beyond the Standard Model. These results are consistent with the Standard Model.", "subitem_description_type": "Abstract"}]}, "item_6_description_5": {"attribute_name": "内容記述", "attribute_value_mlt": [{"subitem_description": "新大博（理）乙第55号", "subitem_description_type": "Other"}]}, "item_6_description_53": {"attribute_name": "学位記番号", "attribute_value_mlt": [{"subitem_description": "新大博（理）乙第55号", "subitem_description_type": "Other"}]}, "item_6_dissertation_number_52": {"attribute_name": "学位授与番号", "attribute_value_mlt": [{"subitem_dissertationnumber": "13101乙第2028号"}]}, "item_6_full_name_3": {"attribute_name": "著者別名", "attribute_value_mlt": [{"nameIdentifiers": [{"nameIdentifier": "48934", "nameIdentifierScheme": "WEKO"}], "names": [{"name": "小貫, 良行"}]}]}, "item_6_publisher_7": {"attribute_name": "出版者", "attribute_value_mlt": [{"subitem_publisher": "新潟大学大学院自然科学研究科"}]}, "item_6_select_19": {"attribute_name": "著者版フラグ", "attribute_value_mlt": [{"subitem_select_item": "author"}]}, "item_creator": {"attribute_name": "著者", "attribute_type": "creator", "attribute_value_mlt": [{"creatorNames": [{"creatorName": "Onuki, Yoshiyuki"}], "nameIdentifiers": [{"nameIdentifier": "48933", "nameIdentifierScheme": "WEKO"}]}]}, "item_files": {"attribute_name": "ファイル情報", "attribute_type": "file", "attribute_value_mlt": [{"accessrole": "open_date", "date": [{"dateType": "Available", "dateValue": "2019-08-05"}], "displaytype": "detail", "download_preview_message": "", "file_order": 0, "filename": "13_0004.pdf", "filesize": [{"value": "29.6 MB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_free", "mimetype": "application/pdf", "size": 29600000.0, "url": {"label": "本文", "url": "https://niigata-u.repo.nii.ac.jp/record/4705/files/13_0004.pdf"}, "version_id": "d541e024-6fca-4bc8-bb54-db803eae400a"}]}, "item_keyword": {"attribute_name": "キーワード", "attribute_value_mlt": [{"subitem_subject": "decay amplitude", "subitem_subject_scheme": "Other"}, {"subitem_subject": "triple product correlation", "subitem_subject_scheme": "Other"}, {"subitem_subject": "B→J", "subitem_subject_scheme": "Other"}, {"subitem_subject": "4k*", "subitem_subject_scheme": "Other"}]}, "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": "thesis", "resourceuri": "http://purl.org/coar/resource_type/c_46ec"}]}, "item_title": "Measurement of decay amplitudes and triple product correlations in B +￫J /ψ K *+", "item_titles": {"attribute_name": "タイトル", "attribute_value_mlt": [{"subitem_title": "Measurement of decay amplitudes and triple product correlations in B +￫J /ψ K *+"}, {"subitem_title": "Measurement of decay amplitudes and triple product correlations in B +￫J /ψ K *+", "subitem_title_language": "en"}]}, "item_type_id": "6", "owner": "1", "path": ["455", "564"], "permalink_uri": "http://hdl.handle.net/10191/1477", "pubdate": {"attribute_name": "公開日", "attribute_value": "2007-04-23"}, "publish_date": "2007-04-23", "publish_status": "0", "recid": "4705", "relation": {}, "relation_version_is_last": true, "title": ["Measurement of decay amplitudes and triple product correlations in B +￫J /ψ K *+"], "weko_shared_id": 2}
