论文摘要
我们研究了八个和四个维度的u（n）量规理论中异国情调的激体产生的非扰动校正。 如前所述，可以使用一个仅显示质量中心的依赖性和从质量中心和从一个依赖性的公式来重新定义八维的预势 u（1）量规因子。相反，八个和四个维度的手性相关因子显示出全量规组的非平凡依赖性。此外，在八和四维情况下，可以以紧凑的形式编写分解，即八和四维相关器的生成函数。
We study the non-perturbative corrections generated by exotic instantons in U(N) gauge theories in eight and four dimensions. As it was shown previously, the eight-dimensional prepotential can be resummed using a plethystic formula showing only a dependence from the center of mass and from a U(1) gauge factor. On the contrary, chiral correlators in eight and four dimensions display a non-trivial dependence from the full gauge group. Furthermore the resolvent, the generating function for the eight and four dimensional correlators, can be written in a compact form both in the eight and four dimensional cases.
