论文摘要
通过二重性方法，我们在存在参数$ c $的情况下通过DILATON壁的背景研究了QCD真空的冷凝水质量，该$ C $代表了全息图中的Gluon凝结。首先，来自Wilson线计算，我们发现$ M^2_0 $（混合非局部冷凝）中的行为模拟QCD的行为。我们通过这种方法发现的$ M^2_0 $的值与QCD数据一致。在第二步中，我们考虑在存在参数$ c $的情况下通过施温格效应机制产生的质量m。我们表明，Gluon凝结通常会贡献质量，并通过Schwinger效应产生质量，并被$ M_0 $抑制。
By duality approach, we study condensate mass of QCD vacuum via dilaton wall background in presence of parameter $c$ which represents the gluon condensation in holographic set up. First from Wilson line calculation we find $m^2_0$ (condensate parameter in mixed nonlocal condensation) whose behavior mimics that of QCD. The value of $m^2_0$ that we find by this approach, is in agreement with QCD data. In the second step we consider produced mass m via Schwinger effect mechanism in presence of parameter $c$. We show that generally gluon condensation contribute mass dominantly and produced mass via Schwinger effect is suppressed by $m_0$ .
