非紧水平对称模型中手征生成的新混合结构

New Mixing Structures of Chiral Generations in a Model with Noncompact Horizontal Symmetry

Naoki Yamatsu

摘要:

在具有水平对称性SU(1,1)的类矢量模型中,给出了低能基本粒子手征各代之间的新混合结构。在此框架下,通过水平对称性的自发对称性破缺实现了包含奇数手征世代的手征模型。结果表明,手征各代的Yukawa耦合矩阵具有自然的层次模式,在某些情况下,手征各代的Yukawa耦合矩阵的整体因子,如底夸克和τ轻子的Yukawa耦合常数,会被自然地抑制.

英文摘要:

New mixing structures between chiral generations of elementary particles at low energy are shown in a vectorlike model with a horizontal symmetry SU(1,1). In this framework the chiral model including odd number chiral generations is realized via the spontaneous symmetry breaking of the horizontal symmetry. It is shown that the Yukawa coupling matrices of chiral generations have naturally hierarchical patterns, and in some cases the overall factors of their Yukawa coupling matrices, e.g. the Yukawa coupling constants of the bottom quark and tau lepton are naturally suppressed.
