夸克和轻子质量矩阵等级结构的起源

Origin of Hierarchical Structures of Quark and Lepton Mass Matrices

Yoshio Koide, Hiroyuki Nishiura

摘要:

结果表明,“Yukawaon”模型可以给出夸克和轻子的质量、混合和$CP$破坏参数的统一描述,而不需要使用除带电轻子质量以外的任何与族数有关的层次参数.在这里,我们引入了一个相位矩阵$P={\rm daig}(e^{i ϕ_1}, e^{i ϕ_2}, e^{i ϕ_3})$,相位参数$(ϕ_1, ϕ_2, ϕ_3)$用与族数无关的参数来描述,同时只使用带电轻子质量参数作为与族数相关的参数。本文将$V_{CKM}$和$U_{PMNS}$标准表达式中的$CP$破坏相位参数$δ_{CP}^q$和$δ_{CP}^\ell$分别预测为$δ_{CP}^q \simeq 72^\circ$和$δ_{CP}^\ell \simeq -76^\circ$,即$δ_{CP}^\ell \sim - δ_{CP}^q$。

英文摘要:

It is shown that the so-called "Yukawaon" model can give a unified description of masses, mixing and $CP$ violation parameters of quarks and leptons without using any hierarchical (family number-dependent) parameters besides the charged lepton masses. Here, we have introduced a phase matrix $P={\rm daig}(e^{i ϕ_1}, e^{i ϕ_2}, e^{i ϕ_3})$ with the phase parameters $(ϕ_1, ϕ_2, ϕ_3)$ which are described in terms of family number-independent parameters, together with using only the charged lepton mass parameters as the family number-dependent parameters. In this paper, the $CP$ violating phase parameters $δ_{CP}^q$ and $δ_{CP}^\ell$ in the standard expression of $V_{CKM}$ and $U_{PMNS}$ are predicted as $δ_{CP}^q \simeq 72^\circ$ and $δ_{CP}^\ell \simeq -76^\circ$, respectively, i.e. $δ_{CP}^\ell \sim - δ_{CP}^q$.
