The introduction of the neutrinos makes us possible not only to describe Dirac neutrino masses but also to solve the cosmological problem called the KK graviton problem. This problem is essentially caused by the late time decay of a KK photon into a KK graviton and a photon, and it distorts the spectrum of the cosmic microwave background or the diffuse photon. We point out that, once we introduce right-handed neutrinos to UED models, the KK photon decays dominantly into neutrinos and does not emit a photon. We also discuss sub-dominant modes with a photon in the decay quantitatively, and show that their branching ratios are so small that the spectra are not distorted.","subitem_description_type":"Abstract"}]},"item_119_description_21":{"attribute_name":"注記","attribute_value_mlt":[{"subitem_description":"Electronic version of an article published as International Journal of Modern Physics E,\nVol: 16, Issue: 5(June 2007), 2007, P1571 - P1582,DOI:10.1142/S0218301307006897 (c)copyright World Scientific Publishing Company http://www.worldscinet.com/cgi-bin/details.cgi?id=pii:S0218301307006708&type=html","subitem_description_type":"Other"}]},"item_119_description_29":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"subitem_description":"text","subitem_description_type":"Other"}]},"item_119_description_30":{"attribute_name":"フォーマット","attribute_value_mlt":[{"subitem_description":"application/pdf","subitem_description_type":"Other"}]},"item_119_publisher_11":{"attribute_name":"出版者名","attribute_value_mlt":[{"subitem_publisher":"World Scientific Publishing"}]},"item_119_source_id_14":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"02183013","subitem_source_identifier_type":"ISSN"}]},"item_119_text_27":{"attribute_name":"版","attribute_value_mlt":[{"subitem_text_value":"[著者版]"}]},"item_119_text_3":{"attribute_name":"著者 ローマ字","attribute_value_mlt":[{"subitem_text_value":"Matsumoto, Shigeki"},{"subitem_text_value":"Sato, Joe"},{"subitem_text_value":"Yamanaka, Masato"},{"subitem_text_value":"Senami, Masato"}]},"item_119_text_32":{"attribute_name":"アイテムID","attribute_value_mlt":[{"subitem_text_value":"A1002396"}]},"item_119_text_4":{"attribute_name":"著者 所属","attribute_value_mlt":[{"subitem_text_value":"&EMPTY&"},{"subitem_text_value":"埼玉大学大学院理工学研究科物質科学部門"}]},"item_119_text_5":{"attribute_name":"著者 所属(別言語)","attribute_value_mlt":[{"subitem_text_value":"&EMPTY&"},{"subitem_text_value":"Graduate School of Science and Engineering, Saitama University"}]},"item_119_text_9":{"attribute_name":"年月次","attribute_value_mlt":[{"subitem_text_value":"2007-6"}]},"item_119_version_type_28":{"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_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Matsumoto, Shigeki"},{"creatorName":"マツモト, シゲキ","creatorNameLang":"ja-Kana"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"佐藤, 丈"},{"creatorName":"サトウ, ジョウ","creatorNameLang":"ja-Kana"}],"nameIdentifiers":[{},{}]},{"creatorNames":[{"creatorName":"Yamanaka, Masato"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Senami, Masato"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2018-01-24"}],"displaytype":"detail","filename":"A1002396.pdf","filesize":[{"value":"236.6 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"A1002396.pdf","url":"https://sucra.repo.nii.ac.jp/record/13052/files/A1002396.pdf"},"version_id":"06587125-584e-4227-8c19-9bb5542d433a"}]},"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":"Introducing neutrino mass into universal extra dimension models and solving cosmological problem","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Introducing neutrino mass into universal extra dimension models and solving cosmological problem"}]},"item_type_id":"119","owner":"3","path":["426"],"pubdate":{"attribute_name":"公開日","attribute_value":"2008-01-21"},"publish_date":"2008-01-21","publish_status":"0","recid":"13052","relation_version_is_last":true,"title":["Introducing neutrino mass into universal extra dimension models and solving cosmological problem"],"weko_creator_id":"3","weko_shared_id":3},"updated":"2023-05-15T19:33:11.410444+00:00"}
