我们总结了与电弱对称动力学破缺相关的基本特征。强耦合理论相图的知识作为颜色、味道和物质表示的数量的函数，在试图构建标准模型(SM)的可行扩展时发挥着基本作用。因此，我们将报道具有费米子物质变换的SU(N)规范理论的相图的状态。我们将讨论如何使用相图来构建非粒子模型。然后，我们将回顾Minimal Walking Technicolor(MWT)和其他扩展，如部分测量和拆分Technicolor。MWT是一个足够普遍的对称性模型，可以作为任何旨在动态打破电弱对称性的模型的基准。标准型号仪表联轴器的统一将在SM的彩色技术扩展中重新讨论。增加了一些附录，以回顾一些基本方法并提供有用的详细信息。在其中一个附录中，我们将展示如何通过引入和使用替代的大N极限来获得与SM的新扩展相关的强耦合理论的谱信息。
We summarize basic features associated to dynamical breaking of the electroweak symmetry. The knowledge of the phase diagram of strongly coupled theories as function of the number of colors, flavors and matter representation plays a fundamental role when trying to construct viable extensions of the standard model (SM). Therefore we will report on the status of the phase diagram for SU(N) gauge theories with fermionic matter transforming according to arbitrary representations of the underlying gauge group. We will discuss how the phase diagram can be used to construct unparticle models. We will then review Minimal Walking Technicolor (MWT) and other extensions, such as partially gauged and split technicolor. MWT is a sufficiently general, symmetry wise, model to be considered as a benchmark for any model aiming at breaking the electroweak symmetry dynamically. The unification of the standard model gauge couplings will be revisited within technicolor extensions of the SM. A number of appendices are added to review some basic methods and to provide useful details. In one of the appendices we will show how to gain information on the spectrum of strongly coupled theories relevant for new extensions of the SM by introducing and using alternative large N limits.
