论文摘要
如今,人们普遍认为,gluons虽然在基本QCD Lagrangian的水平上进行了无数的魅力,但通过非阿布尔实施经典的Schwinger机制获得了有效的质量。触发该机制开始的关键动力成分是该理论基本顶点内的复合无质量极点的形成。这些极点进入Gluon繁殖器的演化方程,并非凡地影响顶点的Slavnov-Taylor身份的方式,从而在相应的病房身份诱导了吸烟枪位移。在本文中,我们介绍了与这种动态场景相关的关键概念的全面回顾,强调了功能方法和晶格模拟之间的协同作用,并强调了最近的进步,这些进步证实了QCD中Schwinger机制的作用。
It is widely accepted nowadays that gluons, while massless at the level of the fundamental QCD Lagrangian,acquire an effective mass through the non-Abelian implementation of the classic Schwinger mechanism. The key dynamical ingredient that triggers the onset of this mechanism is the formation of composite massless poles inside the fundamental vertices of the theory. These poles enter in the evolution equation of the gluon propagator, and affect nontrivially the way the Slavnov-Taylor identities of the vertices are resolved,inducing a smoking-gun displacement in the corresponding Ward identities. In this article we present a comprehensive review of the pivotal concepts associated with this dynamical scenario, emphasizing the synergy between functional methods and lattice simulations, and highlighting recent advances that corroborate the action of the Schwinger mechanism in QCD.
