Skyrmions及其全息图的模型无关检验
Model Independent Tests of Skyrmions and Their Holographic Cousins
摘要：
本文描述了手征极限下重子形状因子长距离行为的大$N_c$ QCD的一个新的精确关系。这种模型无关关系被用来检验几种重子模型结构的一致性。所有的四维半经典手征孤子模型都满足这个关系，重子作为5D Skyrmions的Pomarol-Wulzer全息模型也一样。然而，值得注意的是，我们发现Sakai-Sugimoto模型中把重子当作瞬子的全息模型并不满足这个关系。
英文摘要：
We describe a new exact relation for large $N_c$ QCD for the long-distance behavior of baryon form factors in the chiral limit. This model-independent relation is used to test the consistency of the structure of several baryon models. All 4D semiclassical chiral soliton models satisfy the relation, as does the Pomarol-Wulzer holographic model of baryons as 5D Skyrmions. However, remarkably, we find that the holographic model treating baryons as instantons in the Sakai-Sugimoto model does not satisfy the relation.
