论文摘要
三度顶点是复杂的QCD动力学的基本要素，它密不可分地连接到关键的非扰动现象，例如该理论量规部门的质量规模的出现。在本演讲中，我们回顾了从功能方法和晶格模拟之间富有成果的协同作用获得的三胶状顶点的主要理论特性。我们特别关注红外抑制其主要形式和相关零交叉的表现和起源。此外，我们讨论了某些需要该特殊顶点作为输入的特征现象学应用。
The three-gluon vertex is a fundamental ingredient of the intricate QCD dynamics, being inextricably connected to key nonperturbative phenomena, such as the emergence of a mass scale in the gauge sector of the theory. In this presentation, we review the main theoretical properties of the three-gluon vertex in the Landau gauge, obtained from the fruitful synergy between functional methods and lattice simulations. We pay particular attention to the manifestation and origin of the infrared suppression of its main form factors and the associated zero crossing. In addition, we discuss certain characteristic phenomenological applications that require this special vertex as input.
