Quark interchange between a nucleon and a $c\\bar c$ meson leads to the dissociation of the $c\\bar c$ meson. We consider the reactions: $pR \\to \\Lambda_c^+ \\bar{D}^0$, $pR \\to \\Lambda_c^+ \\bar{D}^{*0}$, $pR \\to \\Sigma_c^{++} D^-$, $pR \\to \\Sigma_c^{++} D^{*-}$, $pR \\to \\Sigma_c^{+} \\bar{D}^0$, $pR \\to \\Sigma_c^{+} \\bar{D}^{*0}$, $pR \\to \\Sigma_c^{*++} D^-$, $pR \\to \\Sigma_c^{*++} D^{*-}$, $pR \\to \\Sigma_c^{*+}"},"claims":{"count":0,"items":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2305.00685","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/2305.00685/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"}
