论文摘要
大型蚀刻塑料面板位于Skylab空间站和东京附近的Ohya采石场内,已被用来对宇宙颗粒的通量设置限制。这些塑料颗粒轨道探测器还为与核强烈相互作用的某些重暗物质提供了最佳灵敏度。我们重新访问了Skylab的先前暗物质界限,并结合了几何依赖性阈值,晕速速度分布以及观察到的透过粒子通量的完整核算。这些考虑因素将Skylab边界的质量范围降低了几个数量级。但是,对OHYA数据的新分析涵盖了先前的Skylab结合的一部分,并将暗物质质量排除到普朗克质量。讨论了未来蚀刻塑料暗物质搜索的前景。
Large panels of etched plastic, situated aboard the Skylab Space Station and inside the Ohya quarry near Tokyo, have been used to set limits on fluxes of cosmogenic particles. These plastic particle track detectors also provide the best sensitivity for some heavy dark matter that interacts strongly with nuclei. We revisit prior dark matter bounds from Skylab, and incorporate geometry-dependent thresholds, a halo velocity distribution, and a complete accounting of observed through-going particle fluxes. These considerations reduce the Skylab bound's mass range by a few orders of magnitude. However, a new analysis of Ohya data covers a portion of the prior Skylab bound, and excludes dark matter masses up to the Planck mass. Prospects for future etched plastic dark matter searches are discussed.
