1. 超对称模型中的风味物理研究我们计算了B和K衰变中CP违和和稀有衰变过程的观测值，以及各种超对称模型（如具有中微子质量生成的GUT模型和具有风味对称的模型）中的轻子风味违和。我们澄清了不同情况下与SM预测偏差的模式，并说明了这些结果如何有助于分析当前B工厂的实验数据和规划未来相关的实验项目。超越SM和轻子风味违背的物理学我们详细计算了不同原子核中介子原子的mu-e转换率。我们还在超对称跷跷板模型和左右对称模型中估计了轻子风味违反过程的分支比。高维规范-希格斯统一基于高维规范理论，提出了规范场与希格斯场的统一模型。我们还研究了标准-希格斯统一模型的理论结构和辐射修正。中微子质量和新物理学我们详细研究了伪狄拉克中微子情景是否可以作为中微子振荡的可行模型。我们还研究了通过辐射修正产生小中微子质量的Zee模型中的宇宙学约束，并构建了一个真实的模型。单极矩和电偶极矩。详细研究了超对称模型中磁单极子的电偶极矩，阐明了电偶极矩的产生机理。

1. Study of flavor physics in supersymmetric modelsWe calculated observables of CP violation and rare decay processes in B and K decays and lepton flavor violation in various suersymmetric models such as GUT with neutrino mass generation and a model with flavor symmetry. We clarified patterns of the deviation from the SM prediction in different cases, and showed how these results are useful to analyze data from present B factory experiments and planning of relevant future experimental projects.2. Physics beyond the SM and lepton flavor violationWe calculated mu-e conversion rates in muonic atoms in various nuclei in detail. We also estimated branching ratios of moun and tau lepton flavor violation processes in the supersymmetric seesaw model and the left-right symmetric model.3. Gauge-Higgs unification in higher dimensionsWe proposed a unification model of gauge fields and the Higgs field based on a gauge theory in higher dimensions. We also studied theoretical structure and radiative corrections in gauge-Higgs unification models.4. Neutrino mass and New PhysicsWe studied in detail whether the pseude Dirac neutrino scenario can be a viable model of neutrino oscillations. We also studied cosmological constraints in the Zee model that generates small neutrino masses through radiative corrections and constructed a realistic model.5. Monopole and electric dipole moment.We studied in detail the electric dipole moment of a magnetic monopole in a supersymmetric model and clarified the generation mechanism of the electric dipole moment.
