The gamma-ray spectrum from annihilation of LKP dark matter shows a characteristic peak structure around the LKP mass. We investigate the detectability of this peak structure by considering energy resolution of near-future detectors, and calculate the expected count spectrum of the gamma-ray signal. In order to judge whether the count spectrum contains the LKP signal, the {\\chi} squared test is employed. If the signal is not detected, we set s","authors_text":"Masaki Mori, Satoshi Tsuchida","cross_cats":["hep-ph"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"astro-ph.HE","submitted_at":"2015-02-09T07:28:44Z","title":"The gamma-ray spectrum from annihilation of Kaluza-Klein dark matter and its observability"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1502.02390","kind":"arxiv","version":1},"verdict":{"created_at":null,"id":null,"model_set":{},"one_line_summary":"","pipeline_version":null,"pith_extraction_headline":"","strongest_claim":"","weakest_assumption":""}},"verdict_id":null}}],"author_attestations":[],"timestamp_anchors":[],"storage_attestations":[],"citation_signatures":[],"replication_records":[],"corrections":[],"mirror_hints":[],"record_created":{"event_id":"sha256:2b1d01d4f42f2e152fdf44d6463fb743edaff99a4842ef30bbd896ae680194c0","target":"record","created_at":"2026-05-18T02:27:42Z","signer":{"key_id":"pith-v1-2026-05","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","signer_id":"pith.science","signer_type":"pith_registry"},"payload":{"attestation_state":"computed","canonical_record":{"metadata":{"abstract_canon_sha256":"35162417a0db48bebe0ae75416a553ebce66848c5fbdb88b22b502ba441006f6","cross_cats_sorted":["hep-ph"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"astro-ph.HE","submitted_at":"2015-02-09T07:28:44Z","title_canon_sha256":"5dfcb2e980bafa69e226da5d1a6ce2a3de11a1a610685e0b13bf69372cec95d5"},"schema_version":"1.0","source":{"id":"1502.02390","kind":"arxiv","version":1}},"canonical_sha256":"aee217f4cc090296724fcb7241bfa148c0ffef5780fdc5aa93693c54f7621000","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"aee217f4cc090296724fcb7241bfa148c0ffef5780fdc5aa93693c54f7621000","first_computed_at":"2026-05-18T02:27:42.528655Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T02:27:42.528655Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"AOJX24XbO6/kragmrOxcuTwTDOtUIEBSFbT0IMJNpinEx0TCsSkSTvKBwiGhZVCpaDIGLlgr4KP22PnphT3qAg==","signature_status":"signed_v1","signed_at":"2026-05-18T02:27:42.529415Z","signed_message":"canonical_sha256_bytes"},"source_id":"1502.02390","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:2b1d01d4f42f2e152fdf44d6463fb743edaff99a4842ef30bbd896ae680194c0","sha256:144919173cccda42c38bf8aa648222a14709a63ba226967e7c0c1a7efa2d8807"],"state_sha256":"e884623646e0a84e493b23e0e0d61e7d40d0d97e5b76517ba8b46c9d66b69a90"}
