论文摘要
我们在强耦合中使用近代领先顺序的梯度流进行了有关QCD静态力的最新研究。 QCD静态力的优点是没有$ o（λ_ {\ text {qcd}}）$ renormalon出现在静态电位中，但在晶格QCD计算中的收敛性差。预计梯度流形式主义可以改善收敛性。基于我们的临时计算，我们探讨了任意流动时间$ t $的静态力的属性，以及在限制$ t \ rightarrow 0 $中，这对于晶状体QCD模拟可能很有用。
We review our recent study on the QCD static force using gradient flow at next-to-leading order in the strong coupling. The QCD static force has the advantage of being free of the $O(Λ_{\text{QCD}})$ renormalon appearing in the static potential but suffers from poor convergence in the lattice QCD computations. It is expected that the gradient flow formalism can improve the convergence. Based on our next-to-leading-order calculations, we explore the properties of the static force for arbitrary flow time $t$, as well as in the limit $t\rightarrow 0$, which may be useful for lattice QCD simulations.
