万有引力的有效场论

Effective Field Theory of Gravity to All Orders

Maximilian Ruhdorfer, Javi Serra, Andreas Weiler

摘要:

我们构造了引力的一般有效场论和粒子物理的标准模型,我们称之为GRSMEFT。我们的方法允许系统推导出一组非冗余的操作员的任意尺寸与通用领域的内容和重力。我们明确确定了十维以下的纯重力EFT、八维以下与重力耦合的位移对称标量的EFT以及八维以下GRSMEFT的算子基。所有命令的扩展都很简单。

英文摘要:

We construct the general effective field theory of gravity coupled to the Standard Model of particle physics, which we name GRSMEFT. Our method allows the systematic derivation of a non-redundant set of operators of arbitrary dimension with generic field content and gravity. We explicitly determine the pure gravity EFT up to dimension ten, the EFT of a shift-symmetric scalar coupled to gravity up to dimension eight, and the operator basis for the GRSMEFT up to dimension eight. Extensions to all orders are straightforward.
