AI 中文摘要
超流体氦-4是用于高灵敏度探测暗物质（DM）候选粒子及其他粒子的理想介质。多个合作组已建造并测试了超流体氦探测器，尤其聚焦于亚GeV暗物质质量范围。本文提出一个探测轴子（反）夸克 nuggets（AQN）的新构想：利用大型强子对撞机（LHC）的超流体氦-4冷却系统作为独特的陆基大型暗物质探测器，实现寄生式探测。针对AQN，本文探讨了其在氦气周围金属部件中的传播问题，指出AQN会在其传播径迹周围引发显著加热，进而损坏外壳。
英文摘要
Superfluid helium-4 is an attractive medium for high-sensitivity detection of dark matter (DM) candidates (as well as other particles). There are several collaborations that have built and tested superfluid helium detectors, particularly focusing on the sub-GeV DM mass range. In this paper we discuss a novel idea for detecting Axion (Anti)Quark Nuggets (AQN) by using parasitically the superfluid helium-4 LHC cooling system as a unique large-scale earth bound DM detector. In the case of the AQN, we address the question of propagation in the metal parts surrounding the helium. An AQN induces significant heating around the propagation track that damages the enclosure.
