We explore the possibility that the $\\Omega(2012)$ is a $\\Xi(1530)\\,\\bar K$ molecule, where the binding mechanism is the coupled channel dynamics with the $\\Omega\\,\\eta$ channel. The characteristic signature of a molecular $\\Omega(2012)$ will be its decay into the three body channel $\\Xi \\pi \\bar{K}$, for which we expect a partial decay width of $2-3\\,{\\rm MeV}$. The partial decay width into the $\\Xi \\bar{K}$ channel should lie in the range of $1-11\\,{\\rm MeV}$, a figure compatible with experiment and w"},"claims":{"count":0,"items":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1807.00718","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":""},"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"}
