The joint angular formulae for these processes are presented, and are used to extract the asymmetry parameters in $\\ee$ annihilation data. Base on the current $\\ldc$ data set collected at BESIII, we estimate the experimental sensitivities to measure the parameters $\\alpha_{\\ld\\pi^+}$ for $\\ldc\\to\\ld\\pi^+$, $\\alpha_{\\Sigma^+\\pi^0}$ for $\\ldc\\to\\Sigma^+\\pi^0$ and $\\alpha_{\\usig\\pi^+"},"claims":{"count":0,"items":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1612.05918","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"}
