费米子质量分级和混合的起源是高能物理中尚未解决的最困难的问题之一。解决味道问题的一种可能性是通过扩展标准模型来包括家族对称性。近年来，它已成为非常流行的使用非阿贝尔离散味对称性，因为他们的权力在预测的大轻子混合角中微子振荡实验相关。在这里，我们给出了一个介绍的味道问题和离散的群体，已被用来尝试一个解决方案it.We审查模型的现状，在最近的测量反应堆的角度，我们认为不同的建模方向。使用的黄酮或多希格斯标量模型的建设进行了讨论，以及直接与间接的方法。我们还重点讨论了通过混合和规则和质量和规则实验区分味对称模型的可能性。事实上，我们在这篇评论中说明了从数学到模型构建到实验的完整路径，以便任何有兴趣在该领域开始工作的读者都可以使用本文作为起点，以获得对不同学科领域的广泛概述。
The origin of fermion mass hierarchies and mixings is one of the unresolved and most difficult problems in high-energy physics. One possibility to address the flavour problems is by extending the standard model to include a family symmetry. In the recent years it has become very popular to use non-Abelian discrete flavour symmetries because of their power in the prediction of the large leptonic mixing angles relevant for neutrino oscillation experiments. Here we give an introduction to the flavour problem and to discrete groups that have been used to attempt a solution for it. We review the current status of models in light of the recent measurement of the reactor angle, and we consider different model-building directions taken. The use of the flavons or multi-Higgs scalars in model building is discussed as well as the direct versus indirect approaches. We also focus on the possibility of experimentally distinguishing flavour symmetry models by means of mixing sum rules and mass sum rules. In fact, we illustrate in this review the complete path from mathematics, via model building, to experiments, so that any reader interested in starting work in the field could use this text as a starting point in order to obtain a broad overview of the different subject areas.
