We consider a large-field inflationary scenario where inflation is driven by a vacuum energy symmetry breaking potential and the scalar inflaton field is nonminimally coupled to spacetime curvature. In particular, we focus on the slow-roll phase, adopting a quasi-de Sitter scale factor to properly account for the presence of perturbations and computing the pair production probability associated to the coupling betwee","authors_text":"Alessio Belfiglio, Orlando Luongo, Stefano Mancini","cross_cats":["astro-ph.CO"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"gr-qc","submitted_at":"2023-12-18T18:21:06Z","title":"Superhorizon entanglement from inflationary particle production"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2312.11419","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:e1c90e4e04083ed2d47796d9321c8b1b929f3478b3d52be15a275b1a80dd4481","target":"record","created_at":"2026-07-05T11:18:11Z","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":"4d167acf87aed4c3755f2f4589083e286efed5f87cb432f01bd96efdf38090d0","cross_cats_sorted":["astro-ph.CO"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"gr-qc","submitted_at":"2023-12-18T18:21:06Z","title_canon_sha256":"b458ed5a5f84bba4cd95b71659152e8d3c228197a7ec1dcd22e024c9a53e5e7a"},"schema_version":"1.0","source":{"id":"2312.11419","kind":"arxiv","version":1}},"canonical_sha256":"9d02e13e9256d70c4164ae203c11833aa0762f4c4762f075f405c43881af1da2","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"9d02e13e9256d70c4164ae203c11833aa0762f4c4762f075f405c43881af1da2","first_computed_at":"2026-07-05T11:18:11.036099Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-05T11:18:11.036099Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"BrgsSeWRsD9HM0bK5tLEL2ma+YcnsI6vjfDhLVptnfrHs0nf+cxEtt7IhYWuX6WAexphPnUWKPFYUn+nqZBxAQ==","signature_status":"signed_v1","signed_at":"2026-07-05T11:18:11.036567Z","signed_message":"canonical_sha256_bytes"},"source_id":"2312.11419","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:e1c90e4e04083ed2d47796d9321c8b1b929f3478b3d52be15a275b1a80dd4481","sha256:e684fc0473c83f709a434b3c9678f097115183c3bfc8247ffdff3b27a1253d54"],"state_sha256":"a61f1e1e175b8597d6d0bf7d999221211d8e0d67438bf6b4ae78079c81efaf7c"}
