关于约束Yang-Mills理论中的动力学质量产生

On the dynamical mass generation in confining Yang-Mills theories

S. P. Sorella

摘要:

在补充了可重正化质量项的欧氏杨-米尔斯理论中讨论了胶子的动力学质量产生。质量参数是不自由的,通过服从重整化群的能隙方程以自洽的方式确定。朗道规范的例子是明确地在一个循环的顺序。对统一性问题作了一些评论。

英文摘要:

The dynamical mass generation for gluons is discussed in Euclidean Yang-Mills theories supplemented with a renormalizable mass term. The mass parameter is not free, being determined in a self-consistent way through a gap equation which obeys the renormalization group. The example of the Landau gauge is worked out explicitly at one loop order. A few remarks on the issue of the unitarity are provided.
