具有规范味$U(1)_F$对称性的SM扩展

SM extension with a gauged flavor $U(1)_F$ symmetry

Zurab Tavartkiladze

摘要:

本文研究了具有无反常$U(1)_F$味对称性的标准模型的推广。在此基础上,通过引入右手中微子态,得到了反常自由电荷分配的解,并给出了具有吸引力的纹理零和层次化的汤川矩阵。这给了我们一个自然的层次之间的理解带电费米子质量和Cabibbo-Kobayashi-Maskawa(CKM)矩阵元素。中微子狄拉克和马约拉纳耦合矩阵也有理想的结构,导致成功的中微子振荡与反中微子质量排序。其他有趣的影响所提出的方案也进行了讨论。

英文摘要:

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.
