夸克-轻子质量矩阵中的分级质量和普适混合

Hierarchical masses and universal mixing in quark-lepton mass matrices

Takeshi Fukuyama, Hiroyuki Nishiura

摘要:

进一步发展了夸克和轻子混合矩阵(CKM和MNS)的普适性假设。这个假设解释了为什么CKM几乎是对角的,而MNS几乎是最大混合的。如果该假设为真,则MNS混合矩阵的狄拉克CP违反相位围绕$π$或0有界。构造了实现这一假设的夸克-轻子质量矩阵,给出了上型、下型夸克和中微子质量矩阵之间的简单幂律关系。

英文摘要:

The universality hypothesis for quark and lepton mixing matrices (CKM and MNS) is further developed. This hypothesis explains why the CKM is almost diagonal whereas the MNS is almost maximally mixed. If this hypothesis is true, the Dirac CP violating phase of the MNS mixing matrix is bounded around $π$ or 0. Quark-lepton mass matrices which realizes this hypothesis are constructed, showing simple power law relations among mass matrices for up-type, down-type quarks and neutrinos.
