论文摘要
在QCD的重，静态夸克质量状态中，众所周知，Polyakov环是解反性相变的阶次参数。然而，polyakov循环对光的光，动力夸克的敏感性尚不清楚。另一方面，从手性过渡附近写的有效拉格朗日的角度来看，polyakov循环是一个能量的操作员，因此，应该像任何能量式操作员一样尺度。我们在这里表明，Polyakov Loop和重夸克自由能对手性过渡敏感，即它们的缩放与3- $ d $ o（n）$通用类别中的能量样可观测值一致。
In the heavy, static quark mass regime of QCD, the Polyakov loop is well known to be an order parameter of the deconfinement phase transition; however, the sensitivity of the Polyakov loop to the deconfinement of light, dynamical quarks is less clear. On the other hand, from the perspective of an effective Lagrangian written in the vicinity of the chiral transition, the Polyakov loop is an energy-like operator and should hence scale as any energy-like operator would. We show here that the Polyakov loop and heavy-quark free energy are sensitive to the chiral transition, i.e. their scaling is consistent with energy-like observables in 3-$d$ $O(N)$ universality classes.
