Main results obtained in this project are followings.\n1. If we introduce a certain symmetry which may solve the famous doublet-triplet splitting problem, the mass of gauginos becomes nonuniversal in the framework of gauge mediation supersymmetry breaking. We studied this aspect in an SU(5) model and also the mass spectrum of superpartners. We pointed out that the feature of this spectrum was favored by the μ problem.\n2. In general CP phases in the supersymmetry breaking parameters induce dangerous EDM of an electron and a neutron. We showed that the CP phases in the mass of gauginos can contribute to these EDMs in such a way that they cancel other contributions. In that case large CP phases can be allowed in the supersymmetry breaking parameters. We studied allowed parameter regions of the supersymmetry breaking parameters and discussed the possibility of light Higgs in that case.\n3. We constructed a neutrino model which can realize successful leptogenesis escaping the gravitino problem. We showed that reheating temperature can be lower than the one which is required from the gravitino problem if we construct a model which realizes maximum CP asymmetry and satisfies constraints from neutrino oscillation experiments.\n4. We constructed a model for baryogenesis and dark matter by using a flat direction related to the μ problem.","subitem_description_type":"Abstract"}]},"item_9_description_22":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"研究課題/領域番号:14540251, 研究期間(年度):2002-2004","subitem_description_type":"Other"},{"subitem_description":"出典：「超弦理論におけるコンパクト化と低エネルギー有効理論の研究」研究成果報告書　課題番号14540251\n(KAKEN：科学研究費助成事業データベース（国立情報学研究所）)\n　　　本文データは著者版報告書より作成","subitem_description_type":"Other"}]},"item_9_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.24517/00049251","subitem_identifier_reg_type":"JaLC"}]},"item_9_publisher_17":{"attribute_name":"公開者","attribute_value_mlt":[{"subitem_publisher":"金沢大学数物科学系"}]},"item_9_relation_28":{"attribute_name":"関連URI","attribute_value_mlt":[{"subitem_relation_name":[{"subitem_relation_name_text":"https://kaken.nii.ac.jp/search/?qm=90206384"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://kaken.nii.ac.jp/search/?qm=90206384","subitem_relation_type_select":"URI"}},{"subitem_relation_name":[{"subitem_relation_name_text":"https://kaken.nii.ac.jp/grant/KAKENHI-PROJECT-14540251/"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://kaken.nii.ac.jp/grant/KAKENHI-PROJECT-14540251/","subitem_relation_type_select":"URI"}},{"subitem_relation_name":[{"subitem_relation_name_text":"https://kaken.nii.ac.jp/report/KAKENHI-PROJECT-14540251/145402512004kenkyu_seika_hokoku_gaiyo/"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://kaken.nii.ac.jp/report/KAKENHI-PROJECT-14540251/145402512004kenkyu_seika_hokoku_gaiyo/","subitem_relation_type_select":"URI"}}]},"item_9_version_type_25":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_ab4af688f83e57aa","subitem_version_type":"AM"}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2017-12-08"}],"displaytype":"detail","filename":"SC-PR-SUEMATSU-D-kanen 2006-4p.pdf","filesize":[{"value":"181.5 kB"}],"format":"application/pdf","licensetype":"license_11","mimetype":"application/pdf","url":{"label":"SC-PR-SUEMATSU-D-kanen 2006-4p.pdf","url":"https://kanazawa-u.repo.nii.ac.jp/record/42902/files/SC-PR-SUEMATSU-D-kanen 2006-4p.pdf"},"version_id":"7efdcaaf-deb4-4abf-9bca-3699ec778634"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"jpn"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"research report","resourceuri":"http://purl.org/coar/resource_type/c_18ws"}]},"item_title":"超弦理論におけるコンパクト化と低エネルギー有効理論の研究","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"超弦理論におけるコンパクト化と低エネルギー有効理論の研究"},{"subitem_title":"Study of compactification in superstring and low energy effective theories","subitem_title_language":"en"}]},"item_type_id":"9","owner":"18","path":["2829"],"pubdate":{"attribute_name":"公開日","attribute_value":"2017-12-08"},"publish_date":"2017-12-08","publish_status":"0","recid":"42902","relation_version_is_last":true,"title":["超弦理論におけるコンパクト化と低エネルギー有効理論の研究"],"weko_creator_id":"18","weko_shared_id":-1},"updated":"2023-07-27T14:29:21.634301+00:00"}
