Our results suggest that X(3872) and Y(4260) are in the spectrum of QCD, with J^{PC} = 1^{++} and 1^{--} respectively. Moreover, we obtain the spectrum of heavier exotic mesons with c-s-cbar-ubar (c-u-cbar-sbar), c-s-cbar-dbar (c-d-cbar-sbar), c-s-cbar-sbar, and c-c-cbar-cbar, as the first theoretical predictions from lattice QCD.","authors_text":"Tung-Han Hsieh, TWQCD Collaboration: Ting-Wai Chiu","cross_cats":["hep-ex","hep-ph"],"headline":"","license":"","primary_cat":"hep-lat","submitted_at":"2006-12-21T18:07:54Z","title":"The spectrum of charmonium-like vector mesons in lattice QCD"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"hep-lat/0612025","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":"sha256:3f2de1ef592ecda1b45c6df7523cd5a2ae7dc8836e07be1877c32d5b5c74f0c6","target":"record","created_at":"2026-05-18T04:28:37Z","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":"3ff344c11e2a03d30e8f0103a1381a0d3c58892460371167ebea653d0b403aa5","cross_cats_sorted":["hep-ex","hep-ph"],"license":"","primary_cat":"hep-lat","submitted_at":"2006-12-21T18:07:54Z","title_canon_sha256":"7aaad28fabed445a8cb5bbffddec3e704b915d6e414e7a68ba176513fa268677"},"schema_version":"1.0","source":{"id":"hep-lat/0612025","kind":"arxiv","version":1}},"canonical_sha256":"26265a1dc5f7b48c46722474f27b3094a4452f075a773ef43e0bda645815bff6","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"26265a1dc5f7b48c46722474f27b3094a4452f075a773ef43e0bda645815bff6","first_computed_at":"2026-05-18T04:28:37.804193Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T04:28:37.804193Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"6TAeHvFM61HKVr37o+N5UcXmUzp8RzuF3rrbueKot8TgVLnMu4o+qv6brrm4cyp7qYH28dlNIQgi3+OXUGluCQ==","signature_status":"signed_v1","signed_at":"2026-05-18T04:28:37.804737Z","signed_message":"canonical_sha256_bytes"},"source_id":"hep-lat/0612025","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:3f2de1ef592ecda1b45c6df7523cd5a2ae7dc8836e07be1877c32d5b5c74f0c6","sha256:ce9d7e575a4020e29db78eddedd73048afca059fea27f37daef3155d68578b48"],"state_sha256":"b07adbec5b21d9d62de331f9d7a52e7be857d7e49563026ad5c2dbcd2541de40"}
