Assuming the same relative errors on the angles $(\\alpha,\\beta,\\gamma)$ and the sides $(R_b,R_t)$, we find that the pairs $(\\gamma,\\beta)$ and $(\\gamma,R_b)$ are most efficient in determining $(\\bar\\varrho,\\bar\\eta)$ that describe the apex of the unitarity triangle. They are followed by $(\\alpha,\\beta)$, $(\\alpha,R_b)$, $(R_t,\\beta)$, $(R_t,R_b)$ and $(R_b,\\beta)$. As the set $\\vus$, $\\vcb$, $R_t$ and $\\beta$ appears to be the best candidate for the fundamental set of flavour violating parameters in t"},"claims":{"count":0,"items":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"hep-ph/0207101","kind":"arxiv","version":4},"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"}
