In this work, we study the $CP$ asymmetries in the $\\Lambda_c^+\\to pK^0_S$ and $\\Xi^+_c\\to \\Sigma^+K^0_S$ decays. The time-independent and time-integrated $\\Gamma$-, $\\alpha$-, $\\beta$-, and $\\gamma$-defined $CP$ asymmetries in the chain decay $\\mathcal{B}_{c\\overline 3}\\to \\mathcal{B}K(t)(\\to \\pi^{+}\\pi^{-})$ are derived. It is found that the $CP$ asymmetry in $K^0-\\overline K^0$ mixing cancels out in the $\\alpha$-, $\\beta$-, and $\\gamma$"},"claims":{"count":0,"items":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2509.09503","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":""},"integrity":{"clean":true,"summary":{"advisory":0,"critical":0,"by_detector":{},"informational":0},"endpoint":"/pith/2509.09503/integrity.json","findings":[],"available":true,"detectors_run":[],"snapshot_sha256":"c28c3603d3b5d939e8dc4c7e95fa8dfce3d595e45f758748cecf8e644a296938"},"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"}
