LHC的暗物质:EFT和规范不变性

Dark matter at the LHC: EFTs and gauge invariance

Nicole F. Bell, Yi Cai, James B. Dent, Rebecca K. Leane, Thomas J. Weiler

摘要:

暗物质相互作用的有效场论(EFT)公式已被证明是量化暗物质上LHC边界的一种方便和流行的方法。然而,考虑的一些不可重正化的EFT算子不尊重标准模型的规范对称性。我们仔细讨论了在什么情况下会出现这种算子,并概述了其解释和应用中的潜在问题。

英文摘要:

Effective field theory (EFT) formulations of dark matter interactions have proven to be a convenient and popular way to quantify LHC bounds on dark matter. However, some of the non-renormalizable EFT operators considered do not respect the gauge symmetries of the Standard Model. We carefully discuss under what circumstances such operators can arise, and outline potential issues in their interpretation and application.
