We use the same methods that led us to predict $M(\\Xi_{cc},~J^P{=}1/2^+) = 3627 \\pm 12$ MeV and $M(\\Xi_{cc}^*,~J^P{=}3/2^+) = 3690 \\pm 12$ MeV to predict $M(\\Omega_{cc}^+,J^P{=}1/2^+) = 3692 \\pm 16$ MeV and $M(\\Omega_{cc}^*,~J^P{=} 3/2^+) = 3756 \\pm 16$ MeV. Production and decay are discussed briefly, and predictions for $M(\\Omega_{bc})$ and $M(\\Omega_{bb})$ are included."},"claims":{"count":0,"items":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1803.01657","kind":"arxiv","version":1},"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"}
