In particular, we consider the effect of the resonance caused by second KK particles on the density. We find that the annihilation cross sections relevant to the density are significantly enhanced due to the resonance when the Higgs boson mass is large enough (m_h \\gtrsim 200 GeV). As a result, the mass of the dark matter particle consistent with the WMAP observation is increased compared to the result which does not include any resonance."}]},{"notation":[{"@value":"15 pages, 6 figures"}]}],"creator":[{"@id":"https://cir.nii.ac.jp/crid/1380574094494033793","@type":"Researcher","foaf:name":[{"@value":"Mitsuru Kakizaki"}]},{"@id":"https://cir.nii.ac.jp/crid/1380574094494033792","@type":"Researcher","foaf:name":[{"@value":"Shigeki Matsumoto"}]},{"@id":"https://cir.nii.ac.jp/crid/1380574094494033794","@type":"Researcher","foaf:name":[{"@value":"Yoshio Sato"}]},{"@id":"https://cir.nii.ac.jp/crid/1380574094494033795","@type":"Researcher","foaf:name":[{"@value":"Masato Senami"}]}],"publication":{"publicationIdentifier":[{"@type":"PISSN","@value":"05503213"}],"prism:publicationName":[{"@value":"Nuclear Physics B"}],"dc:publisher":[{"@value":"Elsevier BV"}],"prism:publicationDate":"2006-02","prism:volume":"735","prism:number":"1-3","prism:startingPage":"84","prism:endingPage":"95"},"reviewed":"false","dcterms:accessRights":"http://purl.org/coar/access_right/c_abf2","dc:rights":["https://www.elsevier.com/tdm/userlicense/1.0/","https://www.elsevier.com/legal/tdmrep-license"],"url":[{"@id":"https://api.elsevier.com/content/article/PII:S0550321305010199?httpAccept=text/xml"},{"@id":"https://api.elsevier.com/content/article/PII:S0550321305010199?httpAccept=text/plain"}],"createdAt":"2005-12-20","modifiedAt":"2025-10-09","foaf:topic":[{"@id":"https://cir.nii.ac.jp/all?q=High%20Energy%20Physics%20-%20Phenomenology","dc:title":"High Energy Physics - Phenomenology"},{"@id":"https://cir.nii.ac.jp/all?q=High%20Energy%20Physics%20-%20Phenomenology%20(hep-ph)","dc:title":"High Energy Physics - Phenomenology (hep-ph)"},{"@id":"https://cir.nii.ac.jp/all?q=FOS:%20Physical%20sciences","dc:title":"FOS: Physical sciences"}],"relatedProduct":[{"@id":"https://cir.nii.ac.jp/crid/1360004235011217408","@type":"Article","resourceType":"学術雑誌論文(journal article)","relationType":["isReferencedBy"],"jpcoar:relatedTitle":[{"@value":"Improved discovery of a nearly degenerate model: Minimal universal extra dimension model using<mml:math xmlns:mml=\"http://www.w3.org/1998/Math/MathML\" display=\"inline\"><mml:msub><mml:mi>M</mml:mi><mml:mrow><mml:mi>T</mml:mi><mml:mn>2</mml:mn></mml:mrow></mml:msub></mml:math>at the LHC"}]},{"@id":"https://cir.nii.ac.jp/crid/2051151842044118912","@type":"Article","resourceType":"学術雑誌論文(journal article)","relationType":["isReferencedBy"],"jpcoar:relatedTitle":[{"@value":"Dark matter in the SO(5) × U(1) gauge-Higgs unification"}]}],"dataSourceIdentifier":[{"@type":"CROSSREF","@value":"10.1016/j.nuclphysb.2005.11.022"},{"@type":"OPENAIRE","@value":"doi_dedup___::153a4cdf7a1246793d91309fcc698356"},{"@type":"CROSSREF","@value":"10.1093/ptep/ptu146_references_DOI_2PxydgmPEe9T7rc1xGG37DTvkKo"},{"@type":"CROSSREF","@value":"10.1103/physrevd.84.094015_references_DOI_2PxydgmPEe9T7rc1xGG37DTvkKo"}]}
