Given its briefness and predictability, the minimal seesaw-a simplified version of the canonical seesaw mechanism with only two right-handed neutrino fields-has been studied in depth and from many perspectives, and now it is being pushed close to a position of directly facing experimental tests. This article is intended to provide an up-to-date review of various phenomenological aspects of the minimal seesaw and its associated leptogenesis mechanism in neutrino physics and cosmology. Our focus is on possible flavor structures of such benchmark seesaw and leptogenesis scenarios and confronting their predictions with current neutrino oscillation data and cosmological observations. In this connection particular attention will be paid to the topics of lepton number violation, lepton flavor violation, discrete flavor symmetries, CP violation and antimatter of the Universe.

最小的跷跷板和瘦身模型。

鉴于其简单性和可预测性,已经对深度跷跷板(仅具有两个右手中微子场的经典跷跷板机制的简化版本)进行了深入研究,现在正被推向直接面对的位置。实验测试。本文旨在提供中微子物理学和宇宙学中最小跷跷板的各种现象学方面及其相关瘦发生机制的最新综述。我们的重点是此类基准跷跷板和瘦身情况的可能风味结构,并将其预测与当前的中微子振荡数据和宇宙学观测相对。在这方面,将特别关注以下问题:违反轻子数,违反轻子味,不对称的味道,
