In this paper we compute the $\\Lambda$-hyperon production rates in the hot, dense, and isospin-asymmetric conditions characteristic of post-collapse proto-neutron stars. We find that local $\\Lambda$ chemical equilibration is driven by nonleptonic strangeness-changing reactions, especially $NN\\leftrightarrow N\\Lambda$ scattering, on timescales of order $10^{","authors_text":"Jorge Martin Camalich, Pasquale Dario Serpico, Ruben Zatini, Tobias Fischer","cross_cats":["astro-ph.HE","nucl-th"],"headline":"","license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"hep-ph","submitted_at":"2026-07-02T12:26:28Z","title":"$\\Lambda$ hyperons in core-collapse supernovae: Equilibration and neutrino opacities"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2607.02086","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":"sha256:18d55eef4cc40698323c91a4e49377b98ff2c11c7bc6e270a445498e77de72a6","target":"record","created_at":"2026-07-03T01:17:41Z","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":"55c6a9c9a8ab272bbd8a73a62daaa465d5ee1e12195a470d93b0b6f1a37fea4a","cross_cats_sorted":["astro-ph.HE","nucl-th"],"license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"hep-ph","submitted_at":"2026-07-02T12:26:28Z","title_canon_sha256":"76336caaa7e949bde200e3a6b494e964cce2c503f64941e0914733b22a60cb36"},"schema_version":"1.0","source":{"id":"2607.02086","kind":"arxiv","version":1}},"canonical_sha256":"0a8a929be339ac4b55081fc17e4f77f06653ea8bd097add3af468ca44a078392","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"0a8a929be339ac4b55081fc17e4f77f06653ea8bd097add3af468ca44a078392","first_computed_at":"2026-07-03T01:17:41.818835Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-03T01:17:41.818835Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"nCrDDPaeytASo0LQpNL1ux1hGi2LMXATy5s+D0du4tNSOLLoZfAt9HSLE9oq7inhgPEbJO2VXMSdNx0btanTBg==","signature_status":"signed_v1","signed_at":"2026-07-03T01:17:41.819270Z","signed_message":"canonical_sha256_bytes"},"source_id":"2607.02086","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:18d55eef4cc40698323c91a4e49377b98ff2c11c7bc6e270a445498e77de72a6","sha256:a09407bb0b87a2141995990b4e2714a710f865219904eb529e77a0dc15c91ddc"],"state_sha256":"55c47adb29cfa9552c2cad5466fc959e0fec13fead93308f667e642565353191"}
