论文摘要
我们讨论了KAMIOKA重力波检测器(Kagra)中的Yukawa样长期相互作用(Kagra)的发现前景。我们认为相互作用范围是公里数的顺序,因此暗物质可以同时与多个Kagra镜相互作用。在许多情况下,诱导的信号应变由低于130 Hz的频率主导。由于检测器的几何形状,有一些强烈的方向灵敏度。事实证明,Kagra将能够在运行的几年内限制这种暗物质。通过我们的一组假设,我们期望Kagra每年可以检测到10公斤暗物质的几个事件,而Yukawa的互动范围为10 km,有效的耦合恒定在$ 10^6 $左右。
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 $10^6$.
