| 英文摘要 | In this paper, we propose a simple model based on the S-3 flavor symmetry, in which a perturbation ansatz is suggested that the flavor symmetry is explicitly broken down via S-3 -> Z(2) -> (empty set) in the up-quark sector and via S-3 -> Z(3) -> (empty set) in the down-quark sector. Our model is successful in obtaining the strong hierarchy of mass matrices of both up-type quarks and down-type quarks, but unsuccessful in obtaining the realistic mixing between the third generation and the first two, as in other models based on S-3 flavor symmetry proposed in the literature. Through detailed analysis, we find the reason for the unsuccesses in our model which is related to the reducibility of the three-dimensional representation of the S-3 group. We conclude that any perturbations in mass matrices preserving the partial symmetry of S-3 cannot help getting realistic mixing between the third generation and first two without fine-tuning. |
