However, as has been known for a long time, in many string-based models, the axion coupling parameter F_a is several orders of magnitude higher than the standard cosmological bounds. We re-examine this problem in a variety of models, showing that F_a is close to the GUT scale or above in many models that have GUT-like phenomenology, as well as some that do not. On the other hand, in some models with Standard Model gauge fields supported on vanishing cycles, it is possible for F_a to ","authors_text":"Edward Witten, Peter Svrcek","cross_cats":["astro-ph","hep-ph"],"headline":"","license":"","primary_cat":"hep-th","submitted_at":"2006-05-21T05:05:22Z","title":"Axions In String Theory"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"hep-th/0605206","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":"sha256:81982c7138424b398ef2982ad8b86319c5bea79e766d6d44b7c4d0332590ca3f","target":"record","created_at":"2026-07-04T17:25:46Z","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":"16aae5aed5ecf4117ac9f6fb8c1bfd7003c280433ce5c9573f8fbc756d07bf16","cross_cats_sorted":["astro-ph","hep-ph"],"license":"","primary_cat":"hep-th","submitted_at":"2006-05-21T05:05:22Z","title_canon_sha256":"8a6053af3045081c48dc6173d7b50702f119fdae880722d119007bb19df8dfad"},"schema_version":"1.0","source":{"id":"hep-th/0605206","kind":"arxiv","version":2}},"canonical_sha256":"bc5e8af99f88f952e5deb11b3d5dbd11767c0d8f807302eeddaa313929db83b1","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"bc5e8af99f88f952e5deb11b3d5dbd11767c0d8f807302eeddaa313929db83b1","first_computed_at":"2026-07-04T17:25:46.361713Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-04T17:25:46.361713Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"AxDmVoDsnJ0DU3vjADyqj6Jnn81x74J7ejLBBsZBdmI4qvff9MSEB+l6L6sej01jqXd8eEoMApFjc4MHZd7VDg==","signature_status":"signed_v1","signed_at":"2026-07-04T17:25:46.362112Z","signed_message":"canonical_sha256_bytes"},"source_id":"hep-th/0605206","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:81982c7138424b398ef2982ad8b86319c5bea79e766d6d44b7c4d0332590ca3f","sha256:bcc12d7d620837f86a4c420780f3bdaec402bdbc4ad9ee28bed6c954331bf49e"],"state_sha256":"bc6dc1051ef38c17452a5a4706afb05545c65a1d18e02ec78145652b847f539c"}
