标准模型中规范相互作用和族复制的大统一起源

Grand Unified origin of gauge interactions and families replication in the Standard Model

António P. Morais, Roman Pasechnik, Werner Porod

摘要:

标准模型(SM)在唯象学上的巨大成功表明,它的味结构和规范相互作用可能不是任意的,而是应该有一个基本的第一原理解释。在这项工作中,我们将探讨如何从一个统一的新物理框架捆绑在一起的味道物理和大统一理论(GUT)的概念,SM的基本独特的属性动态出现。这种框架建议由一种新的无异常的超对称手性$\mathrm{E}_6 \times \mathrm{SU}_F(2) \times \mathrm{U}_F(1)$大统一理论含有SM。这个理论最吸引人的涌现性质之一是希格斯物质统一与高度约束的无质量手征部门具有两个普遍的汤川耦合接近大统一尺度。在电弱尺度下,最小SM样有效场论限制的大统一理论代表了一个特定的风味三希格斯二重态模型与所观察到的大层次的夸克质量谱和混合已经在树的水平。

英文摘要:

Tremendous phenomenological success of the Standard Model (SM) suggests that its flavor structure and gauge interactions may not be arbitrary but should have a fundamental first-principle explanation. In this work, we explore how the basic distinctive properties of the SM dynamically emerge from a unified New Physics framework tying together both flavour physics and Grand Unified Theory (GUT) concepts. This framework is suggested by a novel anomaly-free supersymmetric chiral $\mathrm{E}_6 \times \mathrm{SU}_F(2) \times \mathrm{U}_F(1)$ GUT containing the SM. Among the most appealing emergent properties of this theory is the Higgs-matter unification with a highly-constrained massless chiral sector featuring two universal Yukawa couplings close to the GUT scale. At the electroweak scale, the minimal SM-like effective field theory limit of this GUT represents a specific flavored three-Higgs doublet model consistent with the observed large hierarchies in the quark mass spectra and mixing already at tree level.
