In asymmetric nuclear matter such as heavy nuclei, isospin-symmetry breaking is large and it is expected that the mixing property of the mesons changes significantly and the above-mentioned decay width of the \\eta created in such a medium may be e","authors_text":"Shuntaro Sakai, Teiji Kunihiro","cross_cats":["nucl-th"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"hep-ph","submitted_at":"2014-01-10T06:48:01Z","title":"Possible medium effects on \\eta-\\pi^0 mixing and \\eta \\rightarrow \\pi^0 \\pi^+ \\pi^- decay in the asymmetric nuclear matter"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1401.2239","kind":"arxiv","version":2},"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:dd07f8fa9941fa8d46985c46e6bb4b7c4bd945cd23eea1467c9fe77c85b0a9ec","target":"record","created_at":"2026-05-18T02:28:23Z","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":"a4d1eca510f5b2326cd8398b5081ae446509c52d3af12d8400e153c04306f788","cross_cats_sorted":["nucl-th"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"hep-ph","submitted_at":"2014-01-10T06:48:01Z","title_canon_sha256":"f51e079b5af42dfdce205c015a304b1a8e324ea793ad95ec5a6a64325352d830"},"schema_version":"1.0","source":{"id":"1401.2239","kind":"arxiv","version":2}},"canonical_sha256":"d9f3d8fd704bb1996823d5e25c48cb7e90f22e2581b51c041374c97305392bb4","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"d9f3d8fd704bb1996823d5e25c48cb7e90f22e2581b51c041374c97305392bb4","first_computed_at":"2026-05-18T02:28:23.169025Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T02:28:23.169025Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"O/7Oc0ZwRigLeA8YmYknlwbAH3iP9AujJditx3sOleE3gBG9lianRRQ78Dl2ib6nInmUW5kKpmKQ2ZNqfiqsCg==","signature_status":"signed_v1","signed_at":"2026-05-18T02:28:23.169601Z","signed_message":"canonical_sha256_bytes"},"source_id":"1401.2239","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:dd07f8fa9941fa8d46985c46e6bb4b7c4bd945cd23eea1467c9fe77c85b0a9ec","sha256:77ef28c93faac4b49d8d6e5c8a7840d6417fcedba6362fdad5d946a6df4ada51"],"state_sha256":"3079fc78a6859624766183ff511d48a521c6fa93b9ae050501581703ce9b7fb0"}
