Our results explicitly show the attractive property between two heavy mesons. Consequently, a series of possible molecular states are obtained. It is expected that our study might shed some light on the popular discussions of the newly observed XYZ states.","authors_text":"Ming-Tao Li, Wen-Ling Wang, Yu-bing Dong, Zong-Ye Zhang","cross_cats":["hep-ph"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"nucl-th","submitted_at":"2013-03-18T02:30:21Z","title":"A Study of P-wave Heavy Meson Interactions in A Chiral Quark Model"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1303.4140","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:d05ede9a24b3a4ac4d1e8caa96895095452d917b1116e7a4b2fe22a06ed8a6f7","target":"record","created_at":"2026-05-18T03:30:27Z","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":"5d01473217ad8ef25ed357e0c3c76ea96553498f8a179761e8e076a2588a094a","cross_cats_sorted":["hep-ph"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"nucl-th","submitted_at":"2013-03-18T02:30:21Z","title_canon_sha256":"45bf45e05842a9c049d86474a8e183e53303a3eb0b9b7c715ce60d1ee5bf0d3b"},"schema_version":"1.0","source":{"id":"1303.4140","kind":"arxiv","version":2}},"canonical_sha256":"cdc77090c365c7d3b685c301cefaa08b9879c71dd715460f195e032a0d70fd86","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"cdc77090c365c7d3b685c301cefaa08b9879c71dd715460f195e032a0d70fd86","first_computed_at":"2026-05-18T03:30:27.365416Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T03:30:27.365416Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"AXv4F0eRWfcGrQSVQxNlMtXttTFjWJ9kC3UmBGfI/zBIV4Yh43OXsPhRJn7cV7yQ+X6Mi+DTOkHgb3u2xV3uAA==","signature_status":"signed_v1","signed_at":"2026-05-18T03:30:27.366130Z","signed_message":"canonical_sha256_bytes"},"source_id":"1303.4140","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:d05ede9a24b3a4ac4d1e8caa96895095452d917b1116e7a4b2fe22a06ed8a6f7","sha256:bb93495a5e0fe27418d83c543f478dd30990be84a7a0799ab7d37e7c3776ae3e"],"state_sha256":"460bb3d7ae0b16bd0b814e4352fdc0d7eeda31cb6d99678d8d672a1859e838d4"}
