摘要:

最近的B介子异常相干解释TeV尺度的4321规范模型与层次耦合想起的标准模型Yukawas。我们发现,这种模型出现的低能量极限的一个完整的理论的味道,基于一个扭曲的第五维每个标准模型家庭是准本地化在不同的膜。希格斯玻色子被认为是一种伪南布-戈德斯通玻色子,它产生于与4321对称性破缺相同的动力学。这种新颖的结构统一了夸克和轻子的味道非普遍的方式,提供了一个自然的描述味道层次,并解决了电弱层次问题。

英文摘要:

The recent B-meson anomalies are coherently explained at the TeV scale by 4321 gauge models with hierarchical couplings reminiscent of the Standard Model Yukawas. We show that such models arise as the low-energy limit of a complete theory of flavor, based on a warped fifth dimension where each Standard Model family is quasi-localized in a different brane. The Higgs is identified as a pseudo-Nambu-Goldstone boson emerging from the same dynamics responsible for 4321 symmetry breaking. This novel construction unifies quarks and leptons in a flavor non-universal manner, provides a natural description of flavor hierarchies, and addresses the electroweak hierarchy problem.
