Making use of a tensor duality we introduced in arXiv:1808.10475, we analytically compute the full bispectrum of primordial tensor fluctuations during the non-attractor era. During this epoch the shape of the tensor bispectrum is enhanced in the squeezed limit, its amplitude can be amplified with respect to slow-roll models, and tensor non-Gaussianity can exhibit a scale","authors_text":"Cari Powell, Gianmassimo Tasinato, Ivonne Zavala, Maria Mylova, Ogan Ozsoy, Susha Parameswaran","cross_cats":["astro-ph.CO"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"hep-th","submitted_at":"2019-02-13T16:06:50Z","title":"Squeezed tensor non-Gaussianity in non-attractor inflation"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1902.04976","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:c47a0a7bc868667a002b49acd50c25c00749a66c141cb8b8a7906a6edf6e4e58","target":"record","created_at":"2026-07-05T00:06:35Z","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":"a505113c78ab205984785acefdb57b4764264e97d9f5ab78cbf61645943d09f1","cross_cats_sorted":["astro-ph.CO"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"hep-th","submitted_at":"2019-02-13T16:06:50Z","title_canon_sha256":"53aac9920c176e12ac4ba8d4da35ce6672bb9a8436ea70d782fd38c4e265f519"},"schema_version":"1.0","source":{"id":"1902.04976","kind":"arxiv","version":1}},"canonical_sha256":"7d407e9152a3500c04285bbe6cb13cab6bd581cdefe1b9a47045e48d4b0b8bec","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"7d407e9152a3500c04285bbe6cb13cab6bd581cdefe1b9a47045e48d4b0b8bec","first_computed_at":"2026-07-05T00:06:35.070022Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-05T00:06:35.070022Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"ZILKRN1lvEcjfGcWrlZ5aLFxxP3Lgb36Flp/Jo9OB7p/UcgesB4NYlVohL46wIq9js3Q5rsmEB57zPZM1Hc5Dw==","signature_status":"signed_v1","signed_at":"2026-07-05T00:06:35.070477Z","signed_message":"canonical_sha256_bytes"},"source_id":"1902.04976","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:c47a0a7bc868667a002b49acd50c25c00749a66c141cb8b8a7906a6edf6e4e58","sha256:077b70e1ab0a671f5c10e2bab998b4c89a9783e13eb576f6f45603f1b254dc9f"],"state_sha256":"683c39fbba63f529c1d584af78311f150b1da552271d3b8ecdb352bfbf77ebdc"}
