在各种暗物质候选者中，质量低于1eV的玻色子超轻场是很好的动机。最近，已经提出了一些新的方法来寻找超轻的暗物质候选者，在各种尺度上使用激光干涉仪。其中包括我们的建议，寻找类轴子粒子（ALP）和矢量场与激光干涉引力波探测器。通过测量激光的振荡偏振旋转，可以搜索ALP。弱耦合到标准模型扇区的大量矢量场也可以通过测量作用在干涉仪的悬挂镜上的振荡力来搜索。本文综述了利用日本KAGRA引力波探测器寻找超轻暗物质候选者的活动现状。目前正在分析KAGRA在2020年观测运行的数据，以寻找矢量暗物质，并在干涉仪的臂腔传输端口安装偏振光学器件，以在未来的观测运行中寻找ALP。
Among various dark matter candidates, bosonic ultralight fields with masses below 1eV are well motivated. Recently, a number of novel approaches have been put forward to search for ultralight dark matter candidates using laser interferometers at various scales. Those include our proposals to search for axion-like particles (ALPs) and vector fields with laser interferometric gravitational wave detectors. ALPs can be searched for by measuring the oscillating polarization rotation of laser light. Massive vector fields weakly coupled to the standard model sector can also be searched for by measuring the oscillating forces acting on the suspended mirrors of the interferometers. In this paper, the current status of the activities to search for such ultralight dark matter candidates using a gravitational wave detector in Japan, KAGRA, is reviewed. The analysis of data from KAGRA's observing run in 2020 to search for vector dark matter, and the installation of polarization optics to the arm cavity transmission ports of the interferometer to search for ALPs in future observing runs are underway.
