θ = π的bstractMassive QCD自发地破缺CP，并接纳畴壁，畴壁的动力学和相位依赖于味的数量和它们的质量。我们在全息QCD的Witten-Sakai-Sugimoto模型中讨论了这些问题。除了表明这个模型再现所有QCD的期望，我们解决两个有趣的索赔文献。第一个是关于QCD畴壁理论完全被三维物理学捕获的可能性。第二个方面的存在，量子阶段在某些陈-西蒙斯理论耦合到基本问题。这两种说法都得到了弦理论结构的支持。
A bstractMassive QCD at θ = π breaks CP spontaneously and admits domain walls whose dynamics and phases depend on the number of flavors and their masses. We discuss these issues within the Witten-Sakai-Sugimoto model of holographic QCD. Besides showing that this model reproduces all QCD expectations, we address two interesting claims in the literature. The first is about the possibility that the QCD domain-wall theory is fully captured by three-dimensional physics, only. The second regards the existence of quantum phases in certain Chern-Simons theories coupled to fundamental matter. Both claims are supported by the string theory construction.
