In these models first order corrections to the curvature mode function evolution induce effects at second order in the slow roll parameters that are generically greater than ~ 10% and can reach order unity for order unity power spectrum features. From a complete first order expression in generalized slow-roll, we devise a computationally efficient method that is as simple to evaluate as the leading order one and implements consistency relations in a c","authors_text":"Peter Adshead, Wayne Hu","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"astro-ph.CO","submitted_at":"2012-02-29T21:00:52Z","title":"Fast Computation of First-Order Feature-Bispectrum Corrections"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1203.0012","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:a6957da4d3ceb57cf2cfc4d42ba94c4af0cd950e8bfbb19f35e7933b22cf264c","target":"record","created_at":"2026-05-18T03:54:47Z","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":"32c864bdfef8b7763ad9621d3e3a47652be4e3257d64f52833617d4d4335d0d3","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"astro-ph.CO","submitted_at":"2012-02-29T21:00:52Z","title_canon_sha256":"83d1a2d4baf860f2fd7d752bf31a90c5e24cda8ee72ff2551dab2085dfd5ed0b"},"schema_version":"1.0","source":{"id":"1203.0012","kind":"arxiv","version":1}},"canonical_sha256":"11daebc246351364b89b2b36c2f3fc0cfe2b6588fc83bcc30ce47a10c8636b2b","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"11daebc246351364b89b2b36c2f3fc0cfe2b6588fc83bcc30ce47a10c8636b2b","first_computed_at":"2026-05-18T03:54:47.611498Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T03:54:47.611498Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"LytZmwfS3JGJTSiobe6FbFCroNH41azy8CTnKmPT27DgzI+rg+k2OuVnHI8YDbMqh6I/aU7pj/1HDtHGnlrFAA==","signature_status":"signed_v1","signed_at":"2026-05-18T03:54:47.612159Z","signed_message":"canonical_sha256_bytes"},"source_id":"1203.0012","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:a6957da4d3ceb57cf2cfc4d42ba94c4af0cd950e8bfbb19f35e7933b22cf264c","sha256:71dbebf43015f4265172784beaf7df0702b97a8c23a1055e4e620e5105fda08a"],"state_sha256":"62a358ede41ecb0605d969a2448da66fac65c11660c1f3be31ec8d79ded772cf"}
