定向暗物质探测器中的地球阻止效应

Earth's Stopping Effect in Directional Dark Matter Detectors

Chris Kouvaris

摘要:

我们探讨了当暗物质粒子在地下向探测器运动时,暗物质与原子核相互作用产生的停止效应。虽然这种影响对于重暗物质粒子来说可以忽略不计,但是存在参数相空间,在该参数相空间中,暗物质粒子与原子核的地下相互作用可以在光谱中产生可观察到的差异。从下面到达探测器的暗物质粒子可以比从上面到达的粒子具有更少的能量。这些差异可以通过即将到来的定向检测器潜在地检测到。这可以揭示有关原子核与轻暗物质候选物之间相互作用的类型和强度的大量信息。

英文摘要:

We explore the stopping effect that results from interactions between dark matter and nuclei as the dark matter particles travel undergound towards the detector. Although this effect is negligible for heavy dark matter particles, there is parameter phase space where the underground interactions of the dark matter particles with the nuclei can create observable differences in the spectrum. Dark matter particles that arrive on the detector from below can have less energy from the ones arriving from above. These differences can be potentially detectable by upcoming directional detectors. This can unveil a large amount of information regarding the type and strength of interactions between nuclei and light dark matter candidates.
