Though models with the radiative neutrino mass generation are phenomenologically attractive, the complicated relationship between the flavour structure of additional Yukawa matrices and the neutrino mass matrix sometimes is a barrier to explore the models. We introduce a simple prescription to analyze the relation in a class of models with the asymmetric Yukawa structure. We then apply the treatment to the Zee-Babu model as a concrete example of the class and discuss the phenomenological consequences of the model. The combined studies among the neutrino physics, the lepton flavour violation, and the search for the new particles at the collider experiments provide the anatomy of the Zee-Babu model.

尽管具有辐射中微子质量生成的模型在现象学上很有吸引力，但附加 Yukawa 矩阵的风味结构与中微子质量矩阵之间的复杂关系有时是探索模型的障碍。我们引入一个简单的处方来分析一类具有非对称 Yukawa 结构的模型之间的关系。然后，我们将处理应用于 Zee-Babu 模型作为类的具体示例，并讨论该模型的现象学后果。中微子物理学、轻子风味违反以及在对撞机实验中寻找新粒子的综合研究提供了 Zee-Babu 模型的解剖结构。
