论文摘要
在Lüscher-Weisz（LW）的弦乐动作的框架内研究了QCD通量管的密度曲线。使用Wilson的循环在SU（2）Yang-Mills理论中零温度下的Wilson环形形式主义重叠的横向动作曲线和静态夸克之间的电势。我们找到了与晶格数据相匹配的LW字符串的预测，以及$ q \ bar {q} $势势，最高为$ r = 0.32 $ \，fm的小颜色源分离。
The density profile of the QCD flux tube is investigated within the framework of the Lüscher-Weisz (LW) string action with two boundary terms. The transverse action profile and potential between static quarks are considered using Wilson's loop overlap formalism at zero temperature in SU(2) Yang-Mills theory. We find the predictions of the LW string matching the lattice data for the width of the energy-density and $Q\bar{Q}$ potential up to a small color-source separation of $R=0.32$\,fm.
