摘要
In this work the Fritzsch ansatz for the mass matrices is compared with experimental data. To achieve the best possible agreement between the quantities which are derived from the Fritzsch ansatz and the corresponding experimental ones, all parameters of the ansatz are varied so to find the best parameter set that gives the minimal chi-2 value. The physical observables which are taken as inputs are the experimental flavor mixing elements, the quark masses, the CP parameter epsilon(K) and the mixing parameter from B0 B0BAR mixing. The numerical analysis shows that the Fritzsch ansatz can be consistent with experiments but the strange quark mass must be around 99 MeV which is somewhat lower than commonly quoted values and the top quark mass is predicted to be about 109 GeV. Also the results show that it may be possible to eliminate one of the two CP phase parameters of the ansatz.
