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.

1.超对称模型中味物理的研究我们计算了B和K衰变中CP破坏和稀有衰变过程以及各种超对称模型中轻子味破坏的观测值，如中微子质量产生的GUT模型和味对称模型。我们阐明了在不同情况下偏离SM预测的模式，并展示了这些结果如何有助于分析当前B工厂实验的数据和规划相关的未来实验项目.超轻子物理与轻子味破缺我们详细计算了各种核中μ子原子的μ-e转换率。我们还估计了超对称跷跷板模型和左右对称模型中轻子味破坏过程的分支比.基于高维规范理论，我们提出了一个规范场与Higgs场的统一模型。我们还研究了规范-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我们详细研究了赝狄拉克中微子方案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，并构造了一个现实的模型.单极子和电偶极矩：在超对称模型下详细研究了磁介质的电偶极矩，阐明了电偶极矩的产生机制。
