We consider the basis of states $\\eta_b N$, $\\Upsilon N$, $B \\Lambda_b$, $B \\Sigma_b$, $B^* \\Lambda_b$, $B^* \\Sigma_b$, $B^* \\Sigma_b^*$ and find four basic bound states which correspond to $B \\Sigma_b$, $B \\Sigma_b^*$, $B^* \\Sigma_b$ and $B^* \\Sigma_b^*$, decaying mostly into $\\eta_b N$ and $\\Upsilon N$ and with a binding energy about 50-130 MeV with res"},"claims":{"count":0,"items":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1305.0786","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"}
