To this end, the heavy quark-light diquark picture is employed. We find that all masses of the available $\\Lambda_Q$ and $\\Xi_Q$ states can be understood well. The assignments to these states do not appear to contradict the strong decay properties. $\\Lambda_c(2760)^+$ and $\\Xi_c(2980)$ are assigned to the first radial excitations with $J^P = 1/2^+$. $\\Lambda_c(2940)^+$ and $\\Xi_c(3123)$ might be the 2\\emph{"},"claims":{"count":0,"items":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1406.6561","kind":"arxiv","version":4},"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"}
