我们提出了一些最新的结果，从我们的数值研究N=4超对称杨-米尔斯理论制定的时空晶格。基于一种在非零晶格间距下精确保持单一超对称性的结构，我们最近开发了一种改进的晶格作用量，该作用量现已用于大规模计算。在这里，我们更新我们的研究使用这个新的行动，也适用于树级晶格微扰理论，以改善潜在的分析本身。考虑到相对较弱的耦合，我们得到的库仑系数的结果是一致的连续扰动理论。
We present some of the latest results from our numerical investigations of N=4 supersymmetric Yang--Mills theory formulated on a space-time lattice. Based on a construction that exactly preserves a single supersymmetry at non-zero lattice spacing, we recently developed an improved lattice action that is now being employed in large-scale calculations. Here we update our studies of the static potential using this new action, also applying tree-level lattice perturbation theory to improve the analysis of the potential itself. Considering relatively weak couplings, we obtain results for the Coulomb coefficient that are consistent with continuum perturbation theory.
