A relativistic hadronic model with mesons, nucleons, and Delta(1232)isobars is applied. A substantial increase of the widths for the decays omega -> pi gamma* and rho -> pi gamma* is found for photon virtualities in the range 0.3-0.6 GeV. This enhancement has a direct importance for the description of dilepton yields obtained in relativistic heavy-ion collisions.","authors_text":"Agnieszka Bieniek, Anna Baran, Wojciech Broniowski","cross_cats":["hep-ph"],"headline":"","license":"","primary_cat":"nucl-th","submitted_at":"2002-02-14T11:38:13Z","title":"pion-rho-omega vertex in nuclear matter"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"nucl-th/0202043","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":"sha256:203cf5504726b4cab1a0a4e6d1aae11fe61ec47fe24816004947a1b80c81a52d","target":"record","created_at":"2026-05-18T00:36:52Z","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":"432a20e7cb2195df4aa1827cdabdd9d20232da9b3b27b18fe2fe189ceda2cd02","cross_cats_sorted":["hep-ph"],"license":"","primary_cat":"nucl-th","submitted_at":"2002-02-14T11:38:13Z","title_canon_sha256":"db98ac48e91d50734ce0af179a60e53f121d8c25879cd2267c2b1b327e15b850"},"schema_version":"1.0","source":{"id":"nucl-th/0202043","kind":"arxiv","version":1}},"canonical_sha256":"2a40f7a106d94bd9c8dcc39774bf52fc2dfa43f9f8affc459883e946952c14c8","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"2a40f7a106d94bd9c8dcc39774bf52fc2dfa43f9f8affc459883e946952c14c8","first_computed_at":"2026-05-18T00:36:52.937721Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T00:36:52.937721Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"tkEdoCHO091SwgPOkfrzsdreIldsXlCVvEQjMc0zgqfY3hOctGfYSBZmLwy0BIS8RKLmoTFwgl8E/sKDUuW0Ag==","signature_status":"signed_v1","signed_at":"2026-05-18T00:36:52.938235Z","signed_message":"canonical_sha256_bytes"},"source_id":"nucl-th/0202043","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:203cf5504726b4cab1a0a4e6d1aae11fe61ec47fe24816004947a1b80c81a52d","sha256:956f0c0fbfae0149a285bcd79857db5e0fe96a7991f7cabe37e0bc1c7452720a"],"state_sha256":"b017bfe12582f7d5d81d2bc8dfdf958b84560b3700c1c9dd4bbed084fcbd2406"}
