论文摘要
我们使用梯度流来计算带有染色场插入的威尔逊环的静电力。一方面可以将结果与晶格静态能量的数值导数以及另一方面的扰动计算进行比较，从而可以精确提取$λ_0$参数。这项研究可能为染色体和染色场相关因子的梯度流量计算开辟了道路，这些渐变磁场通常在非依赖性有效场理论分解中出现。
We use gradient flow to compute the static force based on a Wilson loop with a chromoelectric field insertion. The result can be compared on one hand to the static force from the numerical derivative of the lattice static energy, and on the other hand to the perturbative calculation, allowing a precise extraction of the $Λ_0$ parameter. This study may open the way to gradient flow calculations of correlators of chromoelectric and chromomagnetic fields, which typically arise in the nonrelativistic effective field theory factorization.
