论文摘要
我们研究了$ \ mathrm {su}（2）（2）\ times \ mathrm {u}（1）$不变有效理论的轴向矢量暗物质散射核的直接检测速率，并将其与LHC覆盖范围进行比较。直接检测实验的当前限制已经使中介质量界定到TEV范围内的WIMP样场景。这激发了对参数空间的一致且系统的探索，以绘制可能抑制速率的可能区域。我们确实确实找到了这样的区域，并着手构建一致的紫外线模型来产生相关的有效理论。然后，我们在相同的参数空间上讨论对撞机和直接检测实验的相应约束。我们发现了一个基准方案，即使在未来的Xenonnt实验中，LHC的约束也将对介体质量具有更大的敏感性。
We study the direct-detection rate for axial-vectorial dark matter scattering off nuclei in an $\mathrm{SU}(2)\times \mathrm{U}(1)$ invariant effective theory and compare it against the LHC reach. Current constraints from direct detection experiments are already bounding the mediator mass to be well into the TeV range for WIMP-like scenarios. This motivates a consistent and systematic exploration of the parameter space to map out possible regions where the rates could be suppressed. We do indeed find such regions and proceed to construct consistent UV models that generate the relevant effective theory. We then discuss the corresponding constraints from both collider and direct-detection experiments on the same parameter space. We find a benchmark scenario, where even for future XENONnT experiment, LHC constraints will have a greater sensitivity to the mediator mass.
