在PandaX-4T实验中寻找轻子门户暗物质

Search for lepton portal dark matter in the PandaX-4T experiment

PandaX Collaboration

AI总结:

本研究利用PandaX-4T调试运行数据,在非相对论有效场论框架下首次对轻子门户暗物质模型进行了灵敏搜索,对狄拉克费米子暗物质给出了强约束,并补充了对撞机与间接探测实验的结果。

摘要:

我们报告了对轻子门户暗物质模型的寻找,其中暗物质与标准模型中的带电轻子耦合。该简化模型自然导致了光子介导的暗物质与原子核的相互作用,使其适用于直接暗物质探测实验。匹配到暗物质的非相对论有效场论框架,我们利用PandaX-4T调试运行的数据报告了对该模型的首次灵敏搜索。我们的结果对狄拉克费米子暗物质给出了强约束,但由于有效光子相互作用的抑制,对马约拉纳暗物质的约束相对较弱。这些约束补充了从对撞机和间接探测实验中获得的结果。

英文摘要:

We report a search for a lepton-portal dark matter model, where dark matter couples to a charged lepton in the standard model. This simplified model naturally leads to photon-mediated dark matter interactions with nuclei, making it suitable for direct dark matter detection experiments. Matching to the framework of non-relativistic effective field theory for dark matter, we report the first sensitive search for this model using data from the PandaX-4T commissioning run. Our results yield strong constraints on Dirac fermion dark matter but relatively weaker constraints on Majorana dark matter due to the suppression of effective photon interactions. These constraints complement those obtained from the collider and indirect detection experiments.
