六维空间中的a函数

The a-function in six dimensions

J. A. Gracey, I. Jack, C. Poole

摘要:

a函数是在偶数维中定义的建议量,其沿着RG流具有单调行为,通过梯度流方程与β函数相关。我们研究了一般标量理论在六个维度的a-函数,使用β-函数的三个循环顺序的MSbar和MSbar计划(后者在这里首次提出在三个循环)。

英文摘要:

The a-function is a proposed quantity defined in even dimensions which has a monotonic behaviour along RG flows, related to the beta-functions via a gradient flow equation. We study the a-function for a general scalar theory in six dimensions, using the beta-functions up to three-loop order for both the MSbar and MOM schemes (the latter presented here for the first time at three loops).
