论文摘要
在此程序中，我们通过使用Gambit框架的基于ARXIV的全球拟合式毛茸茸的暗物质（DM）有效田间理论（EFT）呈现了结果。在这里，我们仅针对描述量规dirac fermion和标准模型夸克之间相互作用的尺寸-6运算符显示结果。我们的全局拟合结合了\ textit {planck}，直接和间接DM检测以及LHC的最新约束。对于低于100 GEV的DM质量，不可能同时满足所有限制，同时保持高能量处的EFT有效性。但是，对于较高的质量，在EFT有效并饱和到观察到的DM丰度的情况下，很大的参数空间区域保持可行。
In this proceeding, we present results from a global fit of Dirac fermion dark matter (DM) effective field theory (EFT) based on arXiv:2106.02056 using the GAMBIT framework. Here we show results only for the dimension-6 operators that describe the interactions between a gauge-singlet Dirac fermion and Standard Model quarks. Our global fit combines the latest constraints from \textit{Planck}, direct and indirect DM detection, and the LHC. For DM mass below 100 GeV, it is impossible to simultaneously satisfy all constraints while maintaining the EFT validity at high energies. For higher masses, however, large regions of parameter space remain viable where the EFT is valid and saturates the observed DM abundance.
