Study of physics beyond the standard model on the basis of the early universe

我们研究了标准模型之外的可能的理论框架及其唯象特征，这些框架是在中微子质量和暗物质的基础上通过最近的各种实验和观测发现的。我们澄清了中微子的性质，如质量和混合和暗物质的性质之间的定量关系，出现在遗迹丰度，直接和间接的搜索。我们将模型扩展到超对称，并建议出现两种类型的暗物质。并对它们的性质进行了定量分析。我们还研究了在这些模型中宇宙中的重子数不对称性。

We studied possible theoretical frameworks beyond the standard model and their phenomenological features on the basis of both neutrino masses and dark matter which were found through various recent experiments and observations. We clarified the quantitative relation between nature of neutrinos such as masses and mixing and nature of dark matter which appears in the relic abundance, direct and indirect searches. We extended the model to be supersymmetric and suggested that there appears two types of dark matter. Their nature was analyzed in the quantitative way. We also studied the baryon number asymmetry in the universe in these models.
