This work explores PBH formation within a curvaton scenario featuring an ultraslow-roll (USR) phase. An inflaton--curvaton mixed field model is presented, where the inflaton drives early inflation and then transits into the USR phase, amplifying the small-scale curvature perturbation. During inflation, the curvaton generates entropy perturbation, which later converts into curvature perturbation after the curvaton decays in the radiation-dom","authors_text":"Bing-Yu Su, Lei Feng, Nan Li","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"astro-ph.CO","submitted_at":"2025-02-20T07:20:31Z","title":"Primordial black holes from the ultraslow-roll phase in the inflaton--curvaton mixed field inflation"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2502.14323","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:b4bb955a9f66d93f5b561bd04a5ba37f4de8c46be525e3f46460499e146ad6de","target":"record","created_at":"2026-07-05T10:17:24Z","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":"9c31beb64a2d54a0229916479c17e7a5a7cb6851cd8b444d4b0e1490cc40cb35","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"astro-ph.CO","submitted_at":"2025-02-20T07:20:31Z","title_canon_sha256":"050dfcad9768a98c52533657ce5f47e55cf2f28e8d09cdb2b0a5acdafb2d7d9b"},"schema_version":"1.0","source":{"id":"2502.14323","kind":"arxiv","version":1}},"canonical_sha256":"7a5944b5f06bd822282a0f18cedd8e938a1d6123f0695e58ed34ccbabeec2615","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"7a5944b5f06bd822282a0f18cedd8e938a1d6123f0695e58ed34ccbabeec2615","first_computed_at":"2026-07-05T10:17:24.371070Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-05T10:17:24.371070Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"FO58WBOfBqJNeO7gpvyYuNfLcGdYDmeJDhIlfZy+Q28gWRj+ssodl9AgdbfJVYnQCKfot1KFrxUgmkrLqbaaBw==","signature_status":"signed_v1","signed_at":"2026-07-05T10:17:24.371602Z","signed_message":"canonical_sha256_bytes"},"source_id":"2502.14323","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:b4bb955a9f66d93f5b561bd04a5ba37f4de8c46be525e3f46460499e146ad6de","sha256:f10df52d10ff22a815679749230a1b0bd424005aaeb4f2ef5e3c99e3af8663ca"],"state_sha256":"d738c86d74099e5efe1c8a59d783a2f2b2eea9017ff4be9d2b5d2c3ed36c47fd"}
