我们使用梯度流的重整化的Polyakov循环在各种表示。我们用改进的交错夸克2+1味QCD和时间范围为$N\tau=6$，$8$，$10$和$12$的格点，计算了重整化Polyakov环在基本、六重态、伴随、十重态、15重态、24重态和27重态等多种表象中的表现.这种方法允许计算的重整化Polyakov回路在一个大的温度范围从$T=116$ MeV到$T=815$ MeV，与小的误差不仅为Polyakov回路在基本的表示，但也为Polyakov回路在更高的表示。我们比较我们的结果与标准的重整化方案，并讨论了Casimir标度的Polyakov循环。
We use the gradient flow for the renormalization of the Polyakov loop in various representations. Using 2+1 flavor QCD with highly improved staggered quarks and lattices with temporal extents of $N_\tau=6$, $8$, $10$ and $12$ we calculate the renormalized Polyakov loop in many representations including fundamental, sextet, adjoint, decuplet, 15-plet, 24-plet and 27-plet. This approach allows for the calculations of the renormalized Polyakov loops over a large temperature range from $T=116$ MeV up to $T=815$ MeV, with small errors not only for the Polyakov loop in fundamental representation, but also for the Polyakov loops in higher representations. We compare our results with standard renormalization schemes and discuss the Casimir scaling of the Polyakov loops.
