论文摘要

在对Snowmass 2021过程的贡献中，我们回顾了标准模型有效田间理论（SMEFT）中的理论发展，重点是在Dimension-8级别及以后的效果。我们回顾了导致Dimension-8和Dimension-9 Smeft Lagrangians完整构建的理论进步。我们讨论获得全端的可能性导致某些SMEFT可观察物的$ 1/λ$扩展，以及运行重新归一化组的当前状态以及对积极性的影响，并简要介绍了构建SMEFT振幅的壳方法。最后，我们提出了几种新的现象学效应，这些效应首先在Dimension-8上产生，并讨论了这些术语对实验分析的影响。

In this contribution to the Snowmass 2021 process we review theoretical developments in the Standard Model Effective Field Theory (SMEFT) with a focus on effects at the dimension-8 level and beyond. We review the theoretical advances that led to the complete construction of the operator bases for the dimension-8 and dimension-9 SMEFT Lagrangians. We discuss the possibility of obtaining all-orders results in the $1/Λ$ expansion for certain SMEFT observables as well as the current status of renormalization group running and implications for positivity, and briefly present the on-shell approach to constructing SMEFT amplitudes. Finally we present several new phenomenological effects that first arise at dimension-8 and discuss the impact of these terms on experimental analyses.
