夸克和轻子混合矩阵的重定相不变量

Rephasing Invariants of Quark and Lepton Mixing Matrices

Elizabeth Jenkins, Aneesh V. Manohar

摘要:

在标准模型的跷跷板机制扩展下,在其低能有效理论中,采用五维Majorana质量算符,得到了夸克和轻子混合矩阵的再定相不变量.我们对基本不变量进行了分类,讨论了它们之间的非平凡关系,并确定了独立不变量,它们以基无关的方式表征混合矩阵中的所有信息。我们还讨论了混合相的允许范围上的限制,并对rephasing不变量,这是从离散的马约拉纳质量矩阵的不变性。

英文摘要:

Rephasing invariants of quark and lepton mixing matrices are obtained in the standard model extended by the seesaw mechanism, and in its low-energy effective theory with the dimension-five Majorana mass operator. We classify the basic invariants, discuss non-trivial relations between them, and determine the independent invariants which characterize all the information in the mixing matrices in a basis-independent way. We also discuss the restrictions on the allowed ranges for the mixing phases, and on the rephasing invariants, which follow from a discrete invariance of the Majorana mass matrix.
