论文摘要
本文研究了具有无异常$ u（1）_f $ floation对称性的标准模型的扩展。随着这种扩展和额外的右中微子状态的添加，发现了自由电荷分配的解决方案，从而使具有吸引力的质地零和分层的Yukawa矩阵。这使我们对充电费米昂质量与Cabibbo-Kobayashi-Maskawa（CKM）矩阵元素之间的层次结构有了自然的了解。中微子狄拉克和主要耦合矩阵也具有理想的结构，导致成功中微子的中微子质量顺序成功中微子振荡。还讨论了提出的方案的其他有趣含义。
An extension of the Standard Model with anomaly free $U(1)_F$ flavor symmetry is studied in this paper. With this extension and the addition of the right-handed neutrino states, the solution of anomaly free charge assignments is found, which gives appealing texture zero and hierarchical Yukawa matrices. This gives us a natural understanding of the hierarchies between charged fermion masses and Cabibbo-Kobayashi-Maskawa (CKM) matrix elements. Neutrino Dirac and Majorana coupling matrices also have desirable structures leading to successful neutrino oscillations with inverted neutrino mass ordering. Other interesting implications of the presented scenario are also discussed.
