Motivated by this, we estimate masses of the doubly-heavy $J=1/2$ baryons $\\Xi_{cc}$, $\\Xi_{bb}$, and $\\Xi_{bc}$, and their $J=3/2$ hyperfine partners, using a method which accurately predicts the masses of ground-state baryons with a single heavy quark. We obtain $M(\\Xi_{cc}) = 3627 \\pm 12$ MeV, $M(\\Xi_{cc}^*)= 3690 \\pm 12$ MeV, $M(\\Xi_{bb}) = 10162 \\pm 12$ MeV, $M(\\Xi_{bb}^*)= 10184 \\pm 12$ MeV, $M(\\Xi_{bc}) = 6914 \\pm 13$ MeV, $M(\\Xi'_{bc}) = 6933 \\pm"},"claims":{"count":0,"items":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1408.5877","kind":"arxiv","version":3},"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"}
