大统一Yukawa矩阵:标准模型费米子质量、夸克混合和CP破坏参数

Grand Unified Yukawa Matrix Ansatz: The Standard Model Fermion Mass, Quark Mixing and CP Violation Parameters

Yong-Chao Zhang, De-Hai Zhang

摘要:

本文提出了一种新的质量矩阵的概念:在大统一(GU)尺度下,标准模型(SM)的汤川耦合矩阵元是GU规范耦合常数\varepsilon \equiv \sqrt{α_{\text{GU}}}的平方根的整数幂,乘以单位阶随机复数.它将SM费米子质量和夸克混合的层次与规范耦合常数联系起来,大大减少了SM参数,并能给出SM费米子质量、夸克混合和CP破坏参数的良好拟合结果。这是一个整洁但非常有效的反倾销。

英文摘要:

We propose a new mass matrix ansatz: At the grand unified (GU) scale, the standard model (SM) Yukawa coupling matrix elements are integer powers of the square root of the GU gauge coupling constant \varepsilon \equiv \sqrt{α_{\text{GU}}}, multiplied by order unity random complex numbers. It relates the hierarchy of the SM ermion masses and quark mixings to the gauge coupling constants, greatly reducing the SM parameters, and can give good fitting results of the SM fermion mass, quark mixing and CP violation parameters. This is a neat but very effective ansatz.
