论文摘要
在Landau-Gauge Quark繁殖器的纯仪表研究中，已经证明了中心涡旋在动态性手性对称性断裂和相应的动力学质量产生中的重要作用。我们提出了调查中心涡流对Landau-gauge繁殖物对动力学轨迹场的影响的初步结果。为了确保对量规场拓扑的敏感性，用重叠的费米计算传播器。去除中心涡旋后，我们发现动态质量产生被抑制。夸克的重态化函数仍然非常平坦，除非在深度红外表现出明显的抑制作用。这些影响在较轻的夸克质量中变得更加突出。
The important role of centre vortices in dynamical chiral symmetry breaking and corresponding dynamical mass generation has been demonstrated in pure gauge studies of the Landau-gauge quark propagator. We present initial results of our investigation into the impact of centre vortex removal on the Landau-gauge propagator on dynamical gauge fields. To ensure sensitivity to the topology of the gauge fields, the propagator is computed with overlap fermions. Upon removal of centre vortices we find that dynamical mass generation is suppressed. The quark renormalisation function remains remarkably flat except in the deep infrared where it exhibits significant suppression. These effects become more prominent at lighter quark masses.
