中微子模型与轻子生成

Neutrino Models and Leptogenesis

Sandy S. C. Law

摘要:

如果热稀薄生成是重子生成问题的正确解决方案,那么中微子的性质在确定宇宙的物质-反物质不对称性方面可以起到至关重要的作用。正因为如此,中微子模型的研究不仅仅是为了产生微小的中微子质量,它很自然地包含了宇宙重子不对称性之谜。为此,我们研究了几种不同的扩展的中微子模型的基础上,I型跷跷板机制,特别强调其leptogenesis的影响。

英文摘要:

Neutrino properties can play a crucial role in determining the matter-antimatter asymmetry of the universe if thermal leptogenesis is the correct solution to the baryogenesis problem. Owing to this, the study of neutrino models goes beyond the mere purpose of generating tiny neutrino masses, and it is natural to incorporate the puzzle of the cosmic baryon asymmetry. To this end, we have investigated several different extensions of the neutrino model based on the type I seesaw mechanism with particular emphasis on their leptogenesis implications.
