In this paper, we derive the relationship between the weak basis invariants (WB) related to CP violation responsible for leptogenesis and CP violation relevant at low energy. We examine all the experimental viable cases of Frampton-Glashow and Yanagida (FGY) model, in order to construct the WB invariants in terms of left handed Majorana neutrino mass matrix elements, and thus finding the necessary and sufficient condition for CP conservation. Further for all the viable FGY texture zeros, we have shown the explicit dependence of WB invariants on Dirac type and Majorana type CP violating phases. In the end, we discuss the implication of such interrelationships on leptogenesis.

最小跷跷板模型和 Leptogenesis 中的 CP 奇弱基不变量

在本文中,我们推导出与负责轻质发生的 CP 违规相关的弱基不变量 (WB) 与低能量相关的 CP 违规之间的关系。我们检查了 Frampton-Glashow 和 Yanagida (FGY) 模型的所有实验可行案例,以根据左手 Majorana 中微子质量矩阵元素构造 WB 不变量,从而找到 CP 守恒的充要条件。此外,对于所有可行的 FGY 纹理零点,我们已经展示了 WB 不变量对 Dirac 型和 Majorana 型 CP 违反阶段的显式依赖性。最后,我们讨论了这种相互关系对瘦素发生的影响。
