We provide gauge/gravity dual descriptions of explicit realizations of the strong coupling sector of composite Higgs models using insights from nonconformal examples of the AdS/CFT correspondence. We calculate particle masses and pion decay constants for proposed Sp(4) and SU(4) gauge theories, where there is the best lattice data for comparison. Our results compare favorably to lattice studies and go beyond those due to a greater flexibility in choosing the fermion content. That content changes the running dynamics and its choice can lead to sizable changes in the bound state masses. We describe top partners by a dual fermionic field in the bulk. Including suitable higher dimension operators can ensure a top mass consistent with the standard model.
我们利用AdS/CFT对应关系中非共形例子的见解，给出了复合希格斯模型强耦合部分的显式实现的规范/引力对偶描述。我们计算了所提出的Sp(4)和SU(4)规范理论的粒子质量和π介子衰变常数，在这些理论中有最佳的格点数据可供比较。我们的结果与格点研究结果相比具有优势，并且由于在选择费米子内容方面具有更大的灵活性，所以超出了格点研究的范围。该内容改变了跑动动力学，其选择可能导致束缚态质量发生相当大的变化。我们用体中的对偶费米子场来描述顶伙伴。包含合适的高维算符可以确保顶质量与标准模型一致。
