Using the isospin symmetry, we determine hadronic $B\\to\\pi\\pi$ parameters from data where new measurements of direct CP violation in $B^0_d\\to\\pi^0\\pi^0$ resolve a discrete ambiguity. With the help of the $SU(3)$ flavour symmetry, the $B\\to\\pi\\pi$ parameters can be converted into their $B\\to\\pi K$ counterparts, thereby allowing us to make predictions of observables. A particularly interesting decay is $B^0_d\\to\\pi^0 K_{\\rm S}$ as it exhibits mixing-induced CP violation. Using an isospin relation, "},"claims":{"count":0,"items":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1806.08783","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"}
