项目摘要
In this project, I investigated the structure of neutrino masse which arises from the see-saw mechanism, in view of various phenomena in the low and high energies. We considered that in the low energy the neutrino oscillation, the lepton number violating processes such as the neutrinoless double beta decay and the mu-meson capture, and in the high energy the leptogenesis and the effective interaction which arises in the supersymmetric unified theory. To discuss these phenomena, we used the renormalization group analysis and its analytic solution.In particular, 1. we analyzed various phenomena by assuming the special neutrino mixing scheme at high energy and showed that this model reproduced the experimental data well and gave various predictions especially about 13 element of neutrino mixing matrix and the Dirac CP phase. 2. We investigated the effect of Majorana CP phases on the lepton flavor violation processes and found that the effect is quite important. 3. Various lepton number violating processes and their possibility to be investigated experimentally in the present and the near future experiment, are investigated systematically. 4. The lepton flavor violation in the decay of Higgs particles which are produced in the Linear Collider. 5. The origin of the dark energy is proposed and its possibility is argued.
在这个项目中,我针对低能和高能的各种现象,研究了由跷跷板机制产生的中微子质量的结构。我们考虑了低能中微子振荡、无中微子双β衰变、μ-介子俘获等轻子数破坏过程,以及高能超对称统一理论中出现的轻子发生和有效相互作用。为了讨论这些现象,我们使用了重正化群分析及其解析解。特别是,1.我们通过假设高能特殊中微子混合方案来分析各种现象,并表明该模型很好地再现了实验数据,并特别给出了各种预测约13个元素的中微子混合矩阵和狄拉克CP相。 2.我们研究了Majorana CP相对轻子风味破坏过程的影响,发现该影响相当重要。 3.系统地研究了各种轻子数破坏过程及其在当前和近期实验中进行实验研究的可能性。 4. 线性对撞机中产生的希格斯粒子衰变中的轻子味破坏。 5.提出了暗能量的起源并论证了它的可能性。
