We examine the final-state rescattering effects on the hadronic B decay rates and their impact on direct CP violation. The color-suppressed neutral modes such as $B^0\\to D^0\\pi^0,\\pi^0\\pi^0,\\rho^0\\pi^0,K^0\\pi^0$ can be substantially enhanced by long-distance rescattering effects. The direct CP-violating partial rate asymmetries in charmless B decays to $\\pi\\pi/\\pi K$ and $\\rho\\pi$ are significantly affected by final-state rescattering and their signs are generally different from that predicted by the short-distance approach. For example, direct CP asymmetry in $B^0\\to\\rho^0\\pi^0$ is increased to around 60% due to final state rescattering effects whereas the short-distance picture gives about 1%. Evidence of direct CP violation in the decay $\\bar B^0\\to K^-\\pi^+$ is now established, while the combined BaBar and Belle measurements of $\\bar B^0\\to\\rho^\\pm\\pi^\\mp$ imply a $3.6\\sigma$ direct CP asymmetry in the $\\rho^+\\pi^-$ mode. Our predictions for CP violation agree with experiment in both magnitude and sign, whereas the QCD factorization predictions seem to have some difficulty with the data. Current data on $\\pi K$ modes seem to violate the isospin sum rule relation, suggesting the presence of electroweak penguin contributions. We have also investigated whether a large transverse polarization in $B\\to \\phi K^*$ can arise from the final-state rescattering of $D^{(*)}\\bar D_s^{(*)}$ into $\\phi K^*$.","external_url":"https://arxiv.org/abs/hep-ph/0409317","cited_by_count":437,"metadata_source":"pith","metadata_fetched_at":"2026-08-05T02:28:24.338817+00:00","pith_arxiv_id":"hep-ph/0409317","created_at":"2026-05-10T06:26:27.184218+00:00","updated_at":"2026-08-05T02:28:24.338817+00:00","title_quality_ok":true,"display_title":"Final State Interactions in Hadronic B Decays","render_title":"Final State Interactions in Hadronic B Decays"},"hub":{"state":{"work_id":"76dabc40-6e5e-493b-a180-e8f25967f581","tier":"hub","tier_reason":"10+ Pith inbound or 1,000+ external citations","pith_inbound_count":14,"external_cited_by_count":437,"distinct_field_count":2,"first_pith_cited_at":"2025-03-05T14:42:56+00:00","last_pith_cited_at":"2026-06-17T03:40:09+00:00","author_build_status":"not_needed","summary_status":"needed","contexts_status":"needed","graph_status":"needed","ask_index_status":"not_needed","reader_status":"not_needed","recognition_status":"not_needed","updated_at":"2026-08-17T02:20:09.720557+00:00","tier_text":"hub"},"tier":"hub","role_counts":[{"context_role":"background","n":2},{"context_role":"method","n":1}],"polarity_counts":[{"context_polarity":"background","n":2},{"context_polarity":"use_method","n":1}],"runs":{},"summary":{},"graph":{},"authors":[]}}
