A definite correlation emerges between the $\\Delta F=2$ amplitudes $\\cM(K^0 \\to \\bar K^0)$, $\\cM(B_d \\to \\bar B_d)$ and $\\cM(B_s \\to \\bar B_s)$, which can resolve the current tension between between $\\cM(K^0 \\to \\bar K^0)$ and $\\cM(B_d \\to \\bar B_d)$, while predicting $\\cM(B_s \\to \\bar B_s)$. In particular, the CP violating asymmetry "},"claims":{"count":0,"items":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1105.2296","kind":"arxiv","version":2},"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"}
