标题： Flavour hierarchies, extended groups and composites

摘要： 在这些记录中，我介绍了一个复合希格斯模型，在这个模型中，第三代和轻代之间的味层次结构自然出现。 特别是，CKM混合角度被抑制，而PMNS矩阵保持无序。 这种味结构是由于模型的扩展非普遍规范对称性和新复合扇区基本费米子的电弱荷的结果，该新复合扇区实现了希格斯玻色子作为一个伪Nambu-Goldstone玻色子。 该模型的详细描述可以在arXiv:2412.14243中找到。 显示英文摘要

摘要： In these proceedings, I present a composite Higgs model in which the flavour hierarchies between the third and light families emerge naturally. In particular, CKM mixing angles turn out to be suppressed while PMNS matrix remains anarchic. This flavour structure arises as a consequence of the extended non-universal gauge symmetry of the model and the electroweak charges of the fundamental fermions of the new composite sector that realises the Higgs boson as a pseudo Nambu-Goldstone boson. The model is described in detail in arXiv:2412.14243.
