We consider the effect of the finite width correction of the $\\rho$ meson. Our numerical calculation shows an obvious correction because of this effect. We find that the finite width effect of the $\\rho$ meson reduces the branching ratios by about 9% to 11% for bottom meson decay channels: $B^+\\to\\bar{D^0}\\rho^+$, $B^0\\to D^-\\rho^+$, and $B^0_s\\to D^-_s\\rho^+$, and increases the branching ratio by about 10% for $\\Lambda_b^0\\to\\Lambda_c^+\\rho^-$."},"claims":{"count":0,"items":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1302.0998","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"}
