Our results are $\\Gamma[X(3823)\\rightarrow\\chi_{_{c0}}\\gamma]=1.2$ keV, $\\Gamma[X(3823)\\rightarrow\\chi_{_{c1}}\\gamma]=265$ keV, $\\Gamma[X(3823)\\rightarrow\\chi_{_{c2}}\\gamma]=57$ keV and $\\Gamma[X(3823)\\rightarrow\\eta_{_c}\\gamma]=1.3$ keV. The ratio ${\\cal B}[X(3823)\\rightarrow\\chi_{_{c2}}\\gamma]/{\\cal B}[X(3823)\\rightarrow\\chi_{_{c1}}\\gamma]=0.22$, agrees with the experimental data. Similarly, the EM decay widths of $\\psi_{_2}(n^{3}D_{_2})$, $n=2,3$, are pred"},"claims":{"count":0,"items":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2208.09667","kind":"arxiv","version":2},"verdict":{"id":null,"model_set":{},"created_at":null,"strongest_claim":"","one_line_summary":"","pipeline_version":null,"weakest_assumption":"","pith_extraction_headline":""},"integrity":{"clean":true,"summary":{"advisory":0,"critical":0,"by_detector":{},"informational":0},"endpoint":"/pith/2208.09667/integrity.json","findings":[],"available":true,"detectors_run":[],"snapshot_sha256":"c28c3603d3b5d939e8dc4c7e95fa8dfce3d595e45f758748cecf8e644a296938"},"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"}
