我们研究了费米实验室短基线中微子（SBN）实验，MicroBooNE，ICARUS和SBND，MeV至GeV尺度的非弹性暗物质通过暗光子介质相互作用的敏感性。这些模型提供了有趣的光热暗物质场景，虽然直接和间接探测实验具有挑战性，但可以进行基于加速器的搜索。我们认为生产的暗扇区状态与费米实验室助推器8 GeV和NuMI 120 GeV的质子束和研究的签名的散射和衰变的重激发暗态的SBN探测器。这些不同的签名探测参数空间的互补区域。所有这三个实验都将能够覆盖新的领域，并有一个极好的近期机会来寻找解释观测到的暗物质丰度的宇宙学目标。
We study the sensitivity of the Fermilab Short-Baseline Neutrino (SBN) experiments, MicroBooNE, ICARUS, and SBND, to MeV- to GeV-scale inelastic dark matter interacting through a dark photon mediator. These models provide interesting scenarios of light thermal dark matter, which, while challenging to probe with direct and indirect detection experiments, are amenable to accelerator-based searches. We consider production of the dark sector states with both the Fermilab Booster 8 GeV and NuMI 120 GeV proton beams and study the signatures of scattering and decay of the heavy excited dark state in the SBN detectors. These distinct signatures probe complementary regions of parameter space. All three experiments will be able to cover new ground, with an excellent near-term opportunity to search for cosmologically motivated targets explaining the observed dark matter abundance.
