SU(2)在格朗道规范胶子和鬼传播子中满足SU(3

SU(2) meets SU(3) in lattice-Landau-gauge gluon and ghost propagators

A. Cucchieri, T. Mendes, O. Oliveira, P. J. Silva

摘要:

对SU(2)和SU(3)纯Yang-Mills理论的格点朗道规范胶子和鬼传播子进行了比较研究。这些数据是专门用等效晶格参数产生的,以便对两种情况进行仔细比较。我们发现这两种理论非常一致。我们的结果似乎证实了Schwinger-Dyson方程关于红外指数与规范群SU(N)无关的预言。

英文摘要:

A comparative study of the lattice Landau gauge gluon and ghost propagators for SU(2) and SU(3) pure Yang-Mills theories is carried out. The data were specially produced with equivalent lattice parameters to allow for a careful comparison of the two cases. We find very good agreement between the two theories. Our results seem to confirm the predicton of Schwinger-Dyson equations that the infrared exponents are independent of the gauge group SU(N).
