Effective couplings of a pseudoscalar meson and two gluons are calculated in a simple model, where the Bethe-Salpeter amplitude is approximated in terms of harmonic-oscillator wave functions. The model is constructed so as to reproduce S-wave meson masses and the values of wave functions at the origin in the sense of the nonrelativistic quark model. In this model Γ(π0→2γ) is reproduced satisfactorily. We obtain an s-dependent mixing angle, which is estimated to be -42.3° and -40.0° for s=Mη2 and s=Mη′2, respectively. Criticism of various estimations of the angle is presented. All the results are shown to be consistent with experiments. The importance of the compositeness of mesons is stressed.","subitem_description_type":"Abstract"}]},"item_10001_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"American Physical Society"}]},"item_10001_relation_14":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_name":[{"subitem_relation_name_text":"10.1103/PhysRevD.18.236"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://doi.org/10.1103/PhysRevD.18.236","subitem_relation_type_select":"DOI"}}]},"item_10001_rights_15":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"© 1978 The American Physical Society"}]},"item_10001_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"05562821","subitem_source_identifier_type":"ISSN"}]},"item_access_right":{"attribute_name":"アクセス権","attribute_value_mlt":[{"subitem_access_right":"metadata only access","subitem_access_right_uri":"http://purl.org/coar/access_right/c_14cb"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"HIRATA, Kohji"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"KOBAYASHI, Tsunehiro"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"TAKAIWA, Yoshinobu "}],"nameIdentifiers":[{}]}]},"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":"Mixing and decays of pseudoscalar mesons in a nonrelativistic quark model with an idea abstracted from quantum chromodynamics","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Mixing and decays of pseudoscalar mesons in a nonrelativistic quark model with an idea abstracted from quantum chromodynamics"},{"subitem_title":"Mixing and decays of pseudoscalar mesons in a nonrelativistic quark model with an idea abstracted from quantum chromodynamics","subitem_title_language":"en"}]},"item_type_id":"10001","owner":"21","path":["113","272"],"pubdate":{"attribute_name":"公開日","attribute_value":"2012-12-12"},"publish_date":"2012-12-12","publish_status":"0","recid":"3278","relation_version_is_last":true,"title":["Mixing and decays of pseudoscalar mesons in a nonrelativistic quark model with an idea abstracted from quantum chromodynamics"],"weko_creator_id":"21","weko_shared_id":21},"updated":"2024-04-26T05:52:04.719094+00:00"}
