Such a coupling modifies the Standard Model particle masses and affects the dynamics of Big Bang Nucleosynthesis. We model the cosmological evolution of the dark matter, taking into account the modifications of the scalar mass by the environment as well as the full dynamics of Big Bang Nucleosynthesis. We find that precision measurements of the helium-4 abundance set stringent constraints on the available parameter space, and that these constraints are strongly affected by both th","authors_text":"Philip S{\\o}rensen, Sergey Sibiryakov, Tien-Tien Yu","cross_cats":["astro-ph.CO"],"headline":"","license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"hep-ph","submitted_at":"2020-06-08T18:00:02Z","title":"BBN constraints on universally-coupled ultralight scalar dark matter"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2006.04820","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":"sha256:5b1e1eceadd1c94ba46c91e1c01d2a5f680497aedbd8a14c1be69c137b7d8281","target":"record","created_at":"2026-07-05T01:59:30Z","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":"16d9024639f1829c64306f8a72fdad8b9e99cf6dcf6d83583761862072b3d645","cross_cats_sorted":["astro-ph.CO"],"license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"hep-ph","submitted_at":"2020-06-08T18:00:02Z","title_canon_sha256":"c8217554cf4eebad6e6acc9c4fdf0c0afe320f84f412e994aa891811a77c3977"},"schema_version":"1.0","source":{"id":"2006.04820","kind":"arxiv","version":2}},"canonical_sha256":"346f6d853f1bf99fd095d9036db998ed698893c65762fe12648068c9c4c73665","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"346f6d853f1bf99fd095d9036db998ed698893c65762fe12648068c9c4c73665","first_computed_at":"2026-07-05T01:59:30.219926Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-05T01:59:30.219926Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"h22HPPpEA3TfAjr74+dq4/+k5JiwxCy11NMOpNA1S6KR/uv+4djXwGMlRKsVy7aF1IZPiN8AwSeyShszzYWkAw==","signature_status":"signed_v1","signed_at":"2026-07-05T01:59:30.220411Z","signed_message":"canonical_sha256_bytes"},"source_id":"2006.04820","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:5b1e1eceadd1c94ba46c91e1c01d2a5f680497aedbd8a14c1be69c137b7d8281","sha256:5239f995308cf3adca30d028af4d32b406b5ff81a52b498418189d05e5102a96"],"state_sha256":"7249e1a4f743ab7afbf46b638049588a4eefa21f34edac28b08623a063c026da"}
