Lina Necib, Jarrett Moon, Taritree Wongjirad, Janet M. Conrad

摘要:

目前和未来的中微子实验可以用来发现暗物质,不仅可以用来寻找暗物质湮灭为中微子的过程,还可以用来研究暗物质本身在探测器中散射标准模型粒子的情况。在这项工作中,我们研究了不同的中微子探测器的灵敏度,一类模型称为提升暗物质,其中一个次主导的组成部分的黑暗部门获得一个大的洛伦兹今天通过湮灭的主导组成部分在一个暗物质密集的区域,如银河系中心或矮球状星系。这项分析的重点是不同的中微子探测器的灵敏度,特别是切伦科夫为基础的超级K和未来的氩为基础的DUNE,以推动暗物质,散射电子。在恒定散射振幅的情况下,我们研究了预期极限与实验特征的关系,如能量阈值、体积和曝光量。我们强调实验特定的功能,使当前和未来的中微子实验是一个强大的工具,在寻找签名的推动暗物质。

英文摘要:

Current and future neutrino experiments can be used to discover dark matter, not only in searches for dark matter annihilating to neutrinos, but also in scenarios where dark matter itself scatters off Standard Model particles in the detector. In this work, we study the sensitivity of different neutrino detectors to a class of models called boosted dark matter, in which a subdominant component of a dark sector acquires a large Lorentz boost today through annihilation of a dominant component in a dark matter-dense region, such as the galactic center or dwarf spheroidal galaxies. This analysis focuses on the sensitivity of different neutrino detectors, specifically the Cherenkov-based Super-K and the future argon-based DUNE to boosted dark matter that scatters off electrons. We study the dependence of the expected limits on the experimental features, such as energy threshold, volume and exposure in the limit of constant scattering amplitude. We highlight experiment-specific features that enable current and future neutrino experiments to be a powerful tool in finding signatures of boosted dark matter.
