T. Saito, M. N. Chernodub, Atsushi Nakamura, V. I. Zakharov

摘要:

研究了中心涡旋对猝灭QCD退禁闭阶段胶子红外性质的影响。我们观察到一个显着的抑制后,从胶子配置的涡旋的胶子传播子在低动量区域的磁分量。电胶子的传播子几乎不受涡旋去除的影响。我们的结果表明,中心涡是负责重要的非微扰性质的磁成分的夸克-胶子等离子体。

英文摘要:

We study influence of center vortices on infrared properties of gluons in the deconfinement phase of quenched QCD. We observe a significant suppression of the magnetic component of the gluon propagator in the low-momentum region after the vortices are removed from the gluon configurations. The propagator of the electric gluon stays almost unaffected by the vortex removal. Our results demonstrate that the center vortices are responsible for important nonperturbative properties of the magnetic component of the quark-gluon plasma.
