论文摘要
我们提倡一个想法，即可以通过分析始终伴随AQN在大气和地下的AQN通道来检测到地球上击中地球的斧头夸克（AQN）。我们对Indrasonic频率$ν\ simeq 5 $ 〜Hz和超压$ΔP\ sim 0.3〜 $ pa的估计值相对较大，尺寸的暗物质（DM）掘金表明，目前可用的仪器的敏感性已经足以检测到现有技术的非常激烈（但很少见）。对更频繁但不太强烈的事件的研究需要一种新型的乐器。我们提出了一种系统研究的检测策略，通过使用分布式的声学感应，并简要提及其他可能的检测方法，以搜索此类相对较弱和频繁的事件。
We advocate an idea that the Axion Quark Nuggets (AQN) hitting the Earth can be detected by analysing the infrasound, acoustic and seismic waves which always accompany the AQN's passage in the atmosphere and underground. Our estimates for the infrasonic frequency $ν\simeq 5$ ~Hz and overpressure $δp\sim 0.3 ~$Pa for relatively large size dark matter (DM) nuggets suggest that sensitivity of presently available instruments is already sufficient to detect very intense (but very rare) events today with existing technology. A study of much more frequent but less intense events requires a new type of instruments. We propose a detection strategy for a systematic study to search for such relatively weak and frequent events by using Distributed Acoustic Sensing and briefly mention other possible detection methods.
