味模型构建的最新进展

Recent Progress in Flavor Model Building

Wolfgang Altmannshofer, Admir Greljo

AI总结:

本文综述了味模型构建的最新进展,重点介绍在夸克扇区解决标准模型味之谜和新物理味之谜的尝试。

摘要:

味之谜仍然是粒子物理学中最引人注目的开放问题之一。在带电费米子的质量和混合中观察到的显著层级定义了标准模型(SM)的味之谜,这是一个深刻的结构性谜团,指向超越标准模型的新物理。同时,在味改变中性流的精确测量中,未发现与标准模型预测的偏差,这对TeV尺度上的新物理施加了严格约束,从而产生了新物理味之谜。这篇综述文章概述了味模型构建中一系列最新进展,特别关注在夸克扇区内解决其中一个或两个谜团的尝试。

英文摘要:

The flavor puzzles remain among the most compelling open questions in particle physics. The striking hierarchies observed in the masses and mixing of charged fermions define the Standard Model (SM) flavor puzzle, a profound structural enigma pointing to physics beyond the SM. Simultaneously, the absence of deviations from SM predictions in precision measurements of flavor-changing neutral currents imposes severe constraints on new physics at the TeV scale, giving rise to the new physics flavor puzzle. This review article provides an overview of a selection of recent advancements in flavor model building, with a particular focus on attempts to address one or both of these puzzles within the quark sector.
