SO(10)GUT中的Clockwork的风味层次

Flavor Hierarchies from Clockwork in SO(10) GUT

K. S. Babu, Shaikh Saad

摘要:

发条机制可以自然地解释小数字的起源,在$SO(10)$大统一理论中实现,以解决费米子质量和混合中的层次起源。我们表明,一个最小的Yukawa部门涉及$10_H$和$\overline{126}_H$的希格斯玻色子,扩展与两个钟表链组成的$16+\overline{16}$矢量类费米子,可以解释的层次模式与所有的Yukawa耦合是一阶。真实质谱的出现并不需要区分三代的对称性。我们在超对称性和非超对称性框架的背景下开发了时钟系统扩展的$SO(10)$ GUT。在非超对称的情况下,该机制的实现假设在一个中间尺度上实现的Peccei-Quinn对称性,与发条扇区携带非平凡的电荷,这解决了强CP问题,并提供了一个暗物质的候选者轴子。

英文摘要:

The clockwork mechanism, which can naturally explain the origin of small numbers, is implemented in $SO(10)$ grand unified theories to address the origin of hierarchies in fermion masses and mixings. We show that a minimal Yukawa sector involving a $10_H$ and $\overline{126}_H$ of Higgs bosons, extended with two clockwork chains consisting of $16+\overline{16}$ vector-like fermions, can explain the hierarchical patterns with all the Yukawa couplings being of order one. Emergence of a realistic mass spectrum does not require any symmetry that distinguishes the three generations. We develop clockwork-extended $SO(10)$ GUTs both in the context of SUSY and non-SUSY frameworks. Implementation of the mechanism in non-SUSY scenario assumes a Peccei-Quinn symmetry realized at an intermediate scale, with the clockwork sector carrying non-trivial charges, which solves the strong CP problem and provides axion as a dark matter candidate.
