绝对X分布与自对偶性
Absolute X-distribution and self-duality
摘要：
QCD真空的各种模型预测它是由主要是自对偶或反自对偶的激发主导的。在这项工作中，我们看看在纯胶SU（3）规范理论的情况下，使用的场强张量的ESTA为基础的定义的自对偶性的趋势。为了衡量这一属性，我们使用绝对X分布方法，该方法旨在量化可以在一对正交子空间中分解的任意随机变量的极化动态趋势。
英文摘要：
Various models of QCD vacuum predict that it is dominated by excitations that are predominantly self-dual or anti-self-dual. In this work we look at the tendency for self-duality in the case of pure-glue SU(3) gauge theory using the overlap-based definition of the field-strength tensor. To gauge this property, we use the absolute X-distribution method which is designed to quantify the dynamical tendency for polarization for arbitrary random variables that can be decomposed in a pair of orthogonal subspaces.
