摘要
在胶子和鬼传播子所满足的耦合的Dyson-Schwinger方程中,采用裸胶子-鬼顶点,利用两种重整化方案：解析延拓方法和减除方法,得到了胶子和鬼传播子的红外行为．计算表明两种重整化方案在红外区对胶子和鬼传播子得到一致的结果．
Two renormalization approaches： the analytic continuation approach and the subtraction approach, are used to obtain the infrared behavior of gluon and ghost propagators in the coupled gluon and ghost Dyson- Schwinger equations, where the three-gluon and gluon-ghost vertices are taken to be bare. The results show that the two renormalization approaches give the same results in the infrared analysis of propagators.
