The a-function in six dimensions
DOI:10.1007/JHEP01(2016)174.png)
摘要
En 中文
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 (MS) over bar and MOM schemes (the latter presented here for the first time at three loops).
