The results indicate that even though heavy quark spin symmetry forbids $S$ wave coupling of $D_1\\bar{D}$ to the ${}^3S_1$ charmonia ($\\psi(nS)$), the $D$ wave coupling is allowed and not negligible. Under this symmetry, the $D_1\\bar{D}$ can couple to ${}^3D_1$ charmonia ($\\psi(nD)$) via both $S$ and $D$ wave, and the overall coupling is around three times larger than that of $\\psi(nS)$. The $X(4260)$ cannot be a pure molecule but a mixture of a charmonium and various charmed"},"claims":{"count":0,"items":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1705.00449","kind":"arxiv","version":4},"verdict":{"id":null,"model_set":{},"created_at":null,"strongest_claim":"","one_line_summary":"","pipeline_version":null,"weakest_assumption":"","pith_extraction_headline":""},"references":{"count":0,"sample":[],"resolved_work":0,"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57","internal_anchors":0},"formal_canon":{"evidence_count":0,"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"author_claims":{"count":0,"strong_count":0,"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"builder_version":"pith-number-builder-2026-05-17-v1"}
