论文摘要
在包括动态费米子的SU（3）晶格集合中，首次确定了中心涡旋。使用差异方法，在未接触的，涡旋变形和仅涡流的字段上计算静态夸克电势。研究了两个动态的集合和一个纯仪表集合，从而探索了动态费米对中心涡流真空的影响。引入了对标准库仑术语的新颖修改，以描述涡旋式电位的远距离行为。这些修改删除了原始合奏中拟合的字符串张力中系统错误的源。我们的纯阳米尔结果与以前的研究一致，在该研究中，预计的中心涡流场仅繁殖大约三分之二的弦乐张力。值得注意的是，我们发现两个动态晶格上的仅涡流场都能够完全再现相应的未触及的弦张力。
For the first time, centre vortices are identified on SU(3) lattice ensembles that include dynamical fermions. Using a variational method, the static quark potential is calculated on untouched, vortex-removed, and vortex-only fields. Two dynamical ensembles and one pure gauge ensemble are studied, allowing for an exploration of the impact of dynamical fermions on the centre-vortex vacuum. Novel modifications to the standard Coulomb term are introduced to describe the long range behaviour of the vortex-removed potential. These modifications remove a source of systematic error in the fitted string tension on the original ensembles. Our pure Yang-Mills result is consistent with previous studies, where projected centre-vortex fields only reproduce approximately two thirds of the string tension. Remarkably, we find that the vortex-only fields on both dynamical lattices are able to fully reproduce the respective untouched string tensions.
