极大阿贝尔规范中的MOM重整化群函数

MOM renormalization group functions in the maximal abelian gauge

J. M. Bell, J. A. Gracey

摘要:

在一个圈的完全对称点处计算了极大阿贝尔规范(MAG)中QCD的单圈三点顶点函数。因此,该理论在由三价顶点定义的各种动量(momentum)方案以及MSbar方案中被重整化。由此,利用单圈转换函数导出了双圈重整化群函数。平行地,我们重复分析的Curci-Ferrari规对应的MAG在一个特定的限制。给出了不同方案下λ参数之间的关系。

英文摘要:

The one loop 3-point vertex functions of QCD in the maximal abelian gauge (MAG) are evaluated at the fully symmetric point at one loop. As a consequence the theory is renormalized in the various momentum (MOM) schemes which are defined by the trivalent vertices, as well as in the MSbar scheme. From these the two loop renormalization group functions in the MOM schemes are derived using the one loop conversion functions. In parallel we repeat the analysis for the Curci-Ferrari gauge which corresponds to the MAG in a specific limit. The relation between the Lambda parameters in different schemes is also provided.
