中微子实验中的轻暗物质

Light Dark Matter at Neutrino Experiments

Yohei Ema, Filippo Sala, Ryosuke Sato

摘要:

被宇宙射线向上散射的亚GeV暗物质粒子获得了足够的动能,可以通过地球上大体积探测器的阈值。然后,我们使用公共超级神冈和MiniBooNE数据推导出一个新的限制暗物质与电子的散射截面延伸到子千电子伏的质量,关闭以前允许的参数空间的宽区域。最后,我们讨论搜索策略和前景,在现有的和计划中的中微子设施。

英文摘要:

Sub-GeV Dark Matter particles upscattered by cosmic rays gain enough kinetic energy to pass the thresholds of large volume detectors on Earth. We then use public Super-Kamiokande and MiniBooNE data to derive a novel limit on the scattering cross section of Dark Matter with electrons that extends down to sub-keV masses, closing a previously allowed wide region of parameter space. We finally discuss search strategies and prospects at existing and planned neutrino facilities.
