The KM phase emerges as the dominant source of CP violation in tree-dominated decays, which are beginning to constrain the unitarity triangle beyond other constraints. Improving precision of CP asymmetry measurements in penguin-dominated decays may indicate the need for new physics.","authors_text":"Michael Gronau","cross_cats":[],"headline":"","license":"","primary_cat":"hep-ph","submitted_at":"2004-07-28T08:46:58Z","title":"CP violation in B meson decays"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"hep-ph/0407316","kind":"arxiv","version":1},"verdict":{"created_at":null,"id":null,"model_set":{},"one_line_summary":"","pipeline_version":null,"pith_extraction_headline":"","strongest_claim":"","weakest_assumption":""}},"verdict_id":null}}],"author_attestations":[],"timestamp_anchors":[],"storage_attestations":[],"citation_signatures":[],"replication_records":[],"corrections":[],"mirror_hints":[],"record_created":{"event_id":"sha256:c5c6a95acd7fa3a3ceedbaa5769d3cc97e2d2c55ad6e7147f457d4affd764e5d","target":"record","created_at":"2026-05-18T02:36:21Z","signer":{"key_id":"pith-v1-2026-05","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","signer_id":"pith.science","signer_type":"pith_registry"},"payload":{"attestation_state":"computed","canonical_record":{"metadata":{"abstract_canon_sha256":"0c15cd6f2f12293b75db614a8f53158be1a95de54a19592d37abc1aadecc10fe","cross_cats_sorted":[],"license":"","primary_cat":"hep-ph","submitted_at":"2004-07-28T08:46:58Z","title_canon_sha256":"227daa1f5dacf92aacf794e9b9998a0b137570a48ad2b88703fea1b98acc23bb"},"schema_version":"1.0","source":{"id":"hep-ph/0407316","kind":"arxiv","version":1}},"canonical_sha256":"28cb0e0d0f3f43fdaffd076d11f80d6940e7f5e2038b5f5cd40e0e207fb6bc06","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"28cb0e0d0f3f43fdaffd076d11f80d6940e7f5e2038b5f5cd40e0e207fb6bc06","first_computed_at":"2026-05-18T02:36:21.121063Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T02:36:21.121063Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"nLiCGxfGmjSJvlxBXLZsxXa1dWPr2g62U7yJ55/AHkWVbltgnrKPiboLIcuexwcC7galiikFxYJcAUWKr80KCw==","signature_status":"signed_v1","signed_at":"2026-05-18T02:36:21.122491Z","signed_message":"canonical_sha256_bytes"},"source_id":"hep-ph/0407316","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:c5c6a95acd7fa3a3ceedbaa5769d3cc97e2d2c55ad6e7147f457d4affd764e5d","sha256:94fec4b95124304da1fb123c964bf7f187ea0642d54de3b77765992b52823b55"],"state_sha256":"96d9e30b11d860b59169e0ddd96f6ed0836ae35889d6e9bee3e96efae39448bc"}
