The couplings between meson-baryon channels, $\\Xi_c \\bar K$, $\\Xi_c^{\\prime} \\bar K$, $\\Xi_c^{*} \\bar K$, $\\Omega_c\\eta$ and $\\Omega_c^{*}\\eta$, and three-quark bare states $\\Omega_c(1P_\\lambda)$ are considered. We predict a bound state $\\Omega_c(2954)$ below the $\\Xi_c \\bar K$ threshold with $(J^P,j)=(1/2^-,0)$, which can be studied in the final states of $\\Omega_c^{(*)} \\pi$ and $\\Omega_c^{(*)} \\gamma$. Also, the resonances $\\Omega_c(3000)$ and $\\Omega_c(3050)$ can be classified as the lowe"},"claims":{"count":0,"items":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2507.06611","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/2507.06611/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"}
