费米子质量矩阵分解的最小味结构

The Minimal Flavor Structure from Decomposition of the Fermion Mass Matrix

Ying Zhang

摘要:

提出了夸克和轻子的最小味结构,通过对费米子质量矩阵的双幺正分解来解决费米子质量等级和味混合问题。实矩阵${\bf M}_0^f$完全响应于家庭质量等级,这是由一个接近平坦的矩阵结构表示。左手幺正相位${\bf F}_L^f$是夸克和轻子混合中CP破坏的起源,它可以解释为Yukawa相互作用态和弱规范态之间的量子效应.最小味结构仅由10个参数实现,没有任何冗余,对应于夸克/轻子扇区中的6个费米子质量、3个混合角和1个CP破坏。这种方法提供了一个独立于特定夸克或轻子味数据的一般味结构。我们验证的味道结构的验证通过再现夸克/轻子质量和混合。一些可能的情况下,产生的风味结构进行了讨论。

英文摘要:

The minimal flavor structures for both quarks and leptons are proposed to address fermion mass hierarchy and flavor mixings by bi-unitary decomposition of the fermion mass matrix. The real matrix ${\bf M}_0^f$ is completely responsive to family mass hierarchy, which is expressed by a close-to-flat matrix structure. The left-handed unitary phase ${\bf F}_L^f$ provides the origin of CP violation in quark and lepton mixings, which can be explained as a quantum effect between Yukawa interaction states and weak gauge states. The minimal flavor structure is realized by just 10 parameters without any redundancy, corresponding to 6 fermion masses, 3 mixing angles and 1 CP violation in the quark/lepton sector. This approach provides a general flavor structure independent of the specific quark or lepton flavor data. We verify the validation of the flavor structure by reproducing quark/lepton masses and mixings. Some possible scenarios that yield the flavor structure are also discussed.
