We use a fully convergent spatial wave function and perform a simultaneous global fit to both the meson and baryon spectra. Our analysis shows that a Yukawa type hyperfine potential leads to a slight bound state for $T_{cc}$ with $(I,S) = (0,1)$ below its lowest threshold, in agreement with recent experimental findings. We also find that $T_{cc}$ is highly likely to be in a compact configuration.","authors_text":"Sungsik Noh, Woosung Park","cross_cats":[],"headline":"","license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"hep-ph","submitted_at":"2023-03-06T17:00:18Z","title":"Observation of $T_{cc}$ and a quark model"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2303.03285","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:e10e7575b1675e141008714835d227767aab127a3b561b62a2ffbe39e3900b7d","target":"record","created_at":"2026-07-05T05:48:54Z","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":"bf24c8ec113ae1b2b0f89efb1216b17ecd044f087ed9e0238caec73de42431d6","cross_cats_sorted":[],"license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"hep-ph","submitted_at":"2023-03-06T17:00:18Z","title_canon_sha256":"37c9f9a5f9bb5cc9f22fcbd1eae7b577012c0516cd87af7b262fd806c7ef339f"},"schema_version":"1.0","source":{"id":"2303.03285","kind":"arxiv","version":2}},"canonical_sha256":"fda02456ee2467fc7ca93cfea3b918a657f92d4262322367424a9229edbe6a2c","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"fda02456ee2467fc7ca93cfea3b918a657f92d4262322367424a9229edbe6a2c","first_computed_at":"2026-07-05T05:48:54.048767Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-05T05:48:54.048767Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"D2SszQUyofeTBedi9Xix5UBy+zM3RBiuFF6ukV13DXvcVJr5I+qax3P1J43FE5dQ2zVUpkanZm82mG6OV6VnDA==","signature_status":"signed_v1","signed_at":"2026-07-05T05:48:54.049255Z","signed_message":"canonical_sha256_bytes"},"source_id":"2303.03285","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:e10e7575b1675e141008714835d227767aab127a3b561b62a2ffbe39e3900b7d","sha256:fdc891cd71567126b2d7e5345ffe47f1a965e16fb69818ea18312f76a6fea47e"],"state_sha256":"29b1d9f74f319d81df1b15cf93361c16fe0f46eecb90ea9803ab964d613194ff"}
