Galileon有效场论中的单圈重整化

One-loop renormalization in Galileon effective field theory

Lavinia Heisenberg, Christian F. Steinwachs

摘要:

我们研究了平坦时空中标量伽利略子的重整化结构。我们明确地计算了紫外发散单圈贡献的2点,3点,4点和5点的功能。我们讨论了结构的counterterterms和他们的层次结构内的有效场论的扩展。我们评论不同的remation计划,包括几何remation,我们的结果可以推广到任意n点函数。

英文摘要:

We investigate the renormalization structure of scalar Galileons in flat spacetime. We explicitly calculate the ultraviolet divergent one-loop contributions to the 2-point, 3-point, 4-point, and 5-point functions. We discuss the structure of the counterterms and their hierarchy within an effective field theory expansion. We comment on different resummation schemes, including a geometric resummation for which our results could be generalized to arbitrary n-point functions.
