摘要:

我们的目标是提供一种统一的观点在两个流行的话题在研究的非微扰方面的杨米尔斯理论在朗道规范:所谓的Gribov-Zwanziger方法和Kugo-Ojima禁闭标准。借用统计热力学的结果,我们表明,施加的Kugo-Ojima限制标准作为边界条件,导致修改后,但可重正化的配分函数。我们验证了所得到的配分函数是等效的Gribov和Zwanziger,它限制了在第一Gribov视界内的路径积分的集成域。构造一个实现边界条件的作用,可以让我们在边界存在的情况下讨论系统的对称性。特别是,传统的BRST对称性被软破。

英文摘要:

We aim to offer a kind of unifying view on two popular topics in the studies of nonperturbative aspects of Yang-Mills theories in the Landau gauge: the so-called Gribov-Zwanziger approach and the Kugo-Ojima confinement criterion. Borrowing results from statistical thermodynamics, we show that imposing the Kugo-Ojima confinement criterion as a boundary condition leads to a modified yet renormalizable partition function. We verify that the resulting partition function is equivalent with the one obtained by Gribov and Zwanziger, which restricts the domain of integration in the path integral within the first Gribov horizon. The construction of an action implementing a boundary condition allows one to discuss the symmetries of the system in the presence of the boundary. In particular, the conventional BRST symmetry is softly broken.
