We point out that a clean signal of $CP$ violation with magnitude of 2Re($\\epsilon$) $\\approx 3.3\\times 10^{-3}$ can manifest in the semileptonic decays $D^{+}\\rightarrow l^{+}\\nu^{~}_{l}K_{S}$ ($K_{L}$) vs $D^{-}\\rightarrow l^{-}\\bar{\\nu}^{~}_{l}K_{S}$ ($K_{L}$). The $CP$ asymmetries are also dominated by 2Re($\\epsilon$) in the two-body nonleptonic decays $D^{\\pm} \\rightarrow ("},"claims":{"count":0,"items":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"hep-ph/9505272","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"}
