An analysis of quark mass matrices and B-anti B mixing

We study the implications of the recent Bd-anti Bd mixing data on the quark sector parameters - mt, s13 and δ - within the three-generation standard model. We derive limits on several experimental quantities: rs, ε'/ε, branching ratios of rare K and B decays. The Fritzsch scheme for quark mass matrices is consistent with the experimental data only if several experimental and theoretical quantities assume values at the limit of their allowed ranges. This allows a unique solution: mt ≅ 85 GeV, s13 ≅ 0.0035, δ ≅ 1000, with many definite predictions. The Stech scheme and its extension by Gronau, Johnson and Schechter are inconsistent with the experimental constraints. We study how a direct measurement of mt or s13 will improve our constraints and predictions. (orig.)
