KAGRA中重暗物质的发现前景

Discovery prospects for heavy dark matter in KAGRA

Chun-Hao Lee, Reinard Primulando, Martin Spinrath

摘要:

讨论了在神冈引力波探测器(KAGRA)中发现具有Yukawa类长程相互作用的千克级暗物质的前景。我们认为,相互作用的范围是在公里的数量级,因此,暗物质可以同时与多个KAGRA镜相互作用。在许多情况下,感应的信号应变由低于约130 Hz的频率支配。由于探测器的几何形状,有一些很强的方向灵敏度。事实证明,KAGRA将能够在几年的运行时间内限制这种暗物质。根据我们的一系列假设,我们预计KAGRA每年可以检测到10公斤暗物质的几个事件,汤川相互作用的范围为10公里,有效耦合常数约为$10^6$。

英文摘要:

We discuss the discovery prospects for kg-scale dark matter with a Yukawa-like long-range interaction in Kamioka Gravitational Wave Detector (KAGRA). We consider the interaction range to be in the order of kilometers, thus the dark matter may interact with multiple KAGRA mirrors simultaneously. The induced signal strain is in many cases dominated by frequencies below about 130 Hz. Due to the geometry of the detector there is some strong directional sensitivity. It turns out that KAGRA would be able to constrain such kind of dark matter within a few years of operation. With our set of assumptions we expect that KAGRA could detect a few events per year for 10 kg dark matter, with a Yukawa interaction with a range of 10 km and an effective coupling constant around $10^6$.
