三胶子顶点的理论与唯象

Theory and phenomenology of the three-gluon vertex

J. Papavassiliou, A. C. Aguilar, M. N. Ferreira

摘要:

三胶子顶点是复杂的QCD动力学的基本组成部分,与关键的非微扰现象密不可分,例如在理论的规范扇区中出现质量标度。在这篇演讲中,我们回顾了朗道规范中三胶子顶点的主要理论性质,这些性质是从泛函方法和晶格模拟之间富有成效的协同作用中获得的。我们特别注意其主要形状因子和相关的零交叉的红外抑制的表现形式和起源。此外,我们讨论了某些特征的现象学应用,需要这个特殊的顶点作为输入。

英文摘要:

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.
