Using the measured cross-section data for $e^+e^-\\to \\gamma X(3872)$ as a reference, we calculate the cross sections for $e^+e^-\\to \\gamma \\chi_{c0}(2P)$ and $e^+e^-\\to \\gamma \\chi_{c2}(2P)$. Since the $\\chi_{c0}(2P)$ and $\\chi_{c2}(2P)$ states predominantly decay into $D\\bar{D}$ final states, we also predict the corresponding $D\\bar{D}$ invariant mass spectrum for the $e^+e^-\\to \\gamma D\\bar{D}$ process. Our results indicate that $e^+e^-\\to \\gamma D\\bar{D"},"claims":{"count":0,"items":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2412.06400","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/2412.06400/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"}
