从微扰论看Yang-Mills理论的红外传播子

Infrared propagators of Yang-Mills theory from perturbation theory

Matthieu Tissier, Nicolas Wschebor

摘要:

我们证明了朗道规范下纯杨-米尔斯理论的鬼子和胶子的关联函数对所有动量都可以用一个圈的计算精确地再现。关键点是使用Faddeev-Popov行动的大规模扩展。与晶格模拟的协议是优秀的d=4。单圈计算还再现了d=3时晶格模拟的所有特征,并自然地解释了d=2时传播子的特性。

英文摘要:

We show that the correlation functions of ghosts and gluons for the pure Yang-Mills theory in Landau gauge can be accurately reproduced for all momenta by a one-loop calculation. The key point is to use a massive extension of the Faddeev-Popov action. The agreement with lattice simulation is excellent in d=4. The one-loop calculation also reproduces all the characteristic features of the lattice simulations in d=3 and naturally explains the pecularities of the propagators in d=2.
