In such a scenario the spectrum of light states includes the Majoron, the pseudo-Nambu Goldstone boson associated with the breaking of the global symmetry. For a broad range of parameters, the Majoron decays to neutrinos at late times, after the cosmic neutrinos have decoupled from the thermal bath, resulting in a secondary contribution to the cosmic neutrino background. We determine the current bounds on this scenario, and explore the possibility of ","authors_text":"Michael Geller, Peizhi Du, Zackaria Chacko","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"hep-ph","submitted_at":"2018-12-28T18:41:25Z","title":"Detecting a Secondary Cosmic Neutrino Background from Majoron Decays in Neutrino Capture Experiments"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1812.11154","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":"sha256:45fc6d99201904588d1dbfad4426dee246726caf55f681aa74296a79ef8b91e7","target":"record","created_at":"2026-07-04T23:51:38Z","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":"da5b9599b2a9b9c979f90180e6f6510daf4e4c739163391e02afa2014505e2b9","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"hep-ph","submitted_at":"2018-12-28T18:41:25Z","title_canon_sha256":"5882d32eb55dc711a47b890a244d1f0a1d39a7cc97eeeaead3bf20bdee516f93"},"schema_version":"1.0","source":{"id":"1812.11154","kind":"arxiv","version":1}},"canonical_sha256":"ee4f448660c1c221705b2f33caeb20d1ef1994f14ad50f77eb4b6088263e8186","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"ee4f448660c1c221705b2f33caeb20d1ef1994f14ad50f77eb4b6088263e8186","first_computed_at":"2026-07-04T23:51:38.404857Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-04T23:51:38.404857Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"eVtjn611svEKovbPdWHeQt+RLS+AW9F1xU2m4vONR87LqLe7NWHVwt+gvS+1p7cHWdcogbTeW1VWq6h103MMDA==","signature_status":"signed_v1","signed_at":"2026-07-04T23:51:38.405267Z","signed_message":"canonical_sha256_bytes"},"source_id":"1812.11154","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:45fc6d99201904588d1dbfad4426dee246726caf55f681aa74296a79ef8b91e7","sha256:65c63784b36dd361cabe9567585d92ac0b14ab0b4a36bfab9898cb02148dab7c"],"state_sha256":"b2b76a21d6262192ffe64914452db5eecced364e1edc6355c3979f4c8b4d6524"}
