The quantity $\\sin^2 (2 \\phi_1 + \\phi_3)$ (\\phi_1=\\beta and \\phi_3=\\gamma) can be cleanly obtained from the study of decays such as B_d^0(t) -> D^{*\\pm} \\rho^\\mp, D^{*\\pm} a_1^{\\mp}, D^{*0} K^{*0}, etc. Similarly, one can use B_s^0(t) -> D_s^{*\\pm} K^{*\\mp} or even B\\pm -> D^{*0}K^*\\pm to extract $\\sin^2 \\phi_3$. There are no penguin contributions to these decays. It is possible that $\\sin^2 (2\\phi_1 "},"claims":{"count":0,"items":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"hep-ph/0104157","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"}
