AI 中文摘要
本文讨论了江门地下中微子实验（JUNO）中微子探测器对亚GeV弱相互作用大质量粒子（WIMPs）产生的核散射事件触发的米格达尔电离信号的灵敏度。利用JUNO的大靶质量和年调制效应，我们发现JUNO液体闪烁体中大量独立且不可区分的WIMP事件的总事例率可从光电倍增管的总暗率中分离出来，对于自旋相关相互作用，这有望在亚GeV质量范围内提供世界领先的灵敏度。
英文摘要
We discuss the sensitivity of the JUNO neutrino detector to the Migdal ionization signal triggered by nuclear scattering events produced by sub-GeV weakly interacting massive particles (WIMPs). Exploiting JUNO's large target mass and the annual modulation effect we find that the aggregate rate from many independent and indistinguishable WIMP events in JUNO's liquid scintillator can be isolated from the total dark rate of the photomultipliers, potentially providing for spin-dependent interactions a world-leading sensitivity across the sub-GeV mass range.
