The process is generated through the exchange of a light scalar of mass of order 300 keV - 50 MeV coupling to photon through loops or higher dimensional operators. For natural values of the couplings and scales, the model can generate a gamma-ray line which can fit with the recently identified 3.5 keV X-ray line.","authors_text":"Emilian Dudas, Lucien Heurtier, Yann Mambrini","cross_cats":["astro-ph.HE","hep-th"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"hep-ph","submitted_at":"2014-04-07T20:00:25Z","title":"Generating X-ray lines from annihilating dark matter"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1404.1927","kind":"arxiv","version":2},"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":"sha256:1c02983dce9fed34866d6aecafe7982334b116ccb3f0577df91473e14970e8f3","target":"record","created_at":"2026-05-18T02:45:22Z","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":"ec2f3252a37c2e454d643453ed108021c76fb227635351be1e6d475a4d38910c","cross_cats_sorted":["astro-ph.HE","hep-th"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"hep-ph","submitted_at":"2014-04-07T20:00:25Z","title_canon_sha256":"7cc231a0a50a92bcc420ff179b469db4efaebf2f8427fe9c8c12b7d26cc1908a"},"schema_version":"1.0","source":{"id":"1404.1927","kind":"arxiv","version":2}},"canonical_sha256":"4a4a69458bb8882095fe406b902b2cc365eca13680452225669266e2c3a6ea4a","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"4a4a69458bb8882095fe406b902b2cc365eca13680452225669266e2c3a6ea4a","first_computed_at":"2026-05-18T02:45:22.174872Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T02:45:22.174872Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"6E04IR9pAYBImgUB4SpWQJtbyk9sXj815KoRTLwF1NTBles+X+Pjl4B3KsJ+EVdvvDS5ptbSIy9EGPvI+u9MCg==","signature_status":"signed_v1","signed_at":"2026-05-18T02:45:22.175325Z","signed_message":"canonical_sha256_bytes"},"source_id":"1404.1927","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:1c02983dce9fed34866d6aecafe7982334b116ccb3f0577df91473e14970e8f3","sha256:7234eef02451b751d725e6eb3dd2d7670d3fd51eae77efde3a0446ec2a2af97f"],"state_sha256":"af0b729329a6294e9790aeda04afb0e756a252cad419d5c7970999d47060fb05"}
