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": [{"nameIdentifier": "6", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "KOBAYASHI, Tsunehiro"}], "nameIdentifiers": [{"nameIdentifier": "710", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "TAKAIWA, Yoshinobu "}], "nameIdentifiers": [{"nameIdentifier": "712", "nameIdentifierScheme": "WEKO"}]}]}, "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"], "permalink_uri": "https://ir.soken.ac.jp/records/3278", "pubdate": {"attribute_name": "公開日", "attribute_value": "2012-12-12"}, "publish_date": "2012-12-12", "publish_status": "0", "recid": "3278", "relation": {}, "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_shared_id": 21}
