摘要

在具有2+1个物理质量的动态交错费米子的QCD真空中，给出了静态夸克-反夸克对所产生的色电场的晶格蒙特卡罗结果。在分离出非扰动的受限部分后，我们用源之间的物理距离的几个值来描述其空间剖面，范围从0.5 fm到断管柱开始。此外，我们还将我们的结果与QCD真空作为无序色磁凝聚体的模型进行了比较。

Unveiling the flux tube structure in full QCD

We present lattice Monte Carlo results on the chromoelectric field created by a static quark–antiquark pair in the vacuum of QCD with 2+1 dynamical staggered fermions at physical masses. After isolating the nonperturbative, confining part of the field, we characterize its spatial profile for several values of the physical distances between the sources, ranging from about 0.5 fm up to the onset of string breaking. Moreover, we compare our results with a model of QCD vacuum as disordered chromomagnetic condensate.
