具有完全交叉梯形截断的双夸克束缚态
Diquark bound states with a completely crossed ladder truncation
摘要：
采用Dyson-Schwinger方法和Munczek-Nemirovsky模型研究了双夸克通道中的Bethe-Salpeter方程。我们的研究的新颖性是一个完全交叉的梯形图在Bethe-Salpeter内核重申。这些图在双夸克通道中由于它们的颜色因子而增强，但在介子通道中没有。在我们的分析中，双夸克束缚态解存在于Bethe-Salpeter方程中。
英文摘要：
The Bethe-Salpeter equation in the diquark channel is investigated by employing the Dyson-Schwinger method together with the Munczek-Nemirovsky model. The novelty of our study is a resummation of completely crossed ladder diagrams in the Bethe-Salpeter kernel. These diagrams are enhanced due to their color factors in the diquark channel, but not in the meson channel. In our analysis, diquark bound-state solutions exist in the Bethe-Salpeter equation.
