The quark-core contribution to the electric polarizability obtainable in quark models of this kind turns out to be in the semirelativistic approaches even smaller than in the nonrelativistic limit.","authors_text":"F.F.Schoberl, Wolfgang Lucha","cross_cats":["hep-ex","nucl-ex","nucl-th"],"headline":"","license":"","primary_cat":"hep-ph","submitted_at":"2002-04-28T14:10:01Z","title":"Electric Polarizability of Mesons in Semirelativistic Quark Models"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"hep-ph/0204325","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":"sha256:15427a52659dd3ed94f0d4d7a60e37a7d121db747f44b9de02a5a02d4aab605a","target":"record","created_at":"2026-05-18T04:17:45Z","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":"39de050ee5330edc3c89fa85e9d61db6c2f71fa637aaedf28d3ef8ceb8b5d216","cross_cats_sorted":["hep-ex","nucl-ex","nucl-th"],"license":"","primary_cat":"hep-ph","submitted_at":"2002-04-28T14:10:01Z","title_canon_sha256":"6e5ae0628fa0c13acac7fa7d1a10c6e556ebc166c43235b41ae44018e570ebc4"},"schema_version":"1.0","source":{"id":"hep-ph/0204325","kind":"arxiv","version":2}},"canonical_sha256":"ab42074ddb620cc450298971b4a45f84460f38680739e4bdb9cf74d19f496ee9","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"ab42074ddb620cc450298971b4a45f84460f38680739e4bdb9cf74d19f496ee9","first_computed_at":"2026-05-18T04:17:45.227411Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T04:17:45.227411Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"DlVl4vo6U2JEheSGkEZHhwW8SoXvQC/GhbGFhuhx6J1rP58snskE+VEH4Y/NMJMJrJpMnkMLH0BZcJLOSAcVBg==","signature_status":"signed_v1","signed_at":"2026-05-18T04:17:45.227809Z","signed_message":"canonical_sha256_bytes"},"source_id":"hep-ph/0204325","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:15427a52659dd3ed94f0d4d7a60e37a7d121db747f44b9de02a5a02d4aab605a","sha256:7956669e5f68fd50f3b43949c9217f6bfd0467be9c5aa38b8fbe5c36740eb0f0"],"state_sha256":"ec77c8f517a19e9fd43368ec7af13c76b913e1424419b0538d8d3e99ada84ccb"}
