AI总结:

本文利用2+1动力学staggered费米子的格点QCD,研究了静态夸克-反夸克对产生的色电场空间分布,并与无序色磁凝聚体模型进行了对比。

摘要:

我们给出了在物理质量下、采用2+1动力学staggered费米子的QCD真空中,由静态夸克-反夸克对产生的色电场格点蒙特卡罗结果。在分离出场的非微扰禁闭部分后,我们对源之间物理距离从约0.5 fm直到弦断裂起始的多个取值,刻画了该场的空间分布。此外,我们将结果与将QCD真空视为无序色磁凝聚体的模型进行了比较。

英文摘要:

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.
