We report on a direct search for scalar field dark matter using data from LIGO's third observing run. We analyze the coupling of size oscillations of the interferometer's beam splitter and arm test masses that may be caused by scalar field dark matter. Using new efficient search methods to maximize sensitivity for signatures of such oscillations, we set new upper limits for the coupling constants of scalar field dark matter as a function of its mass, which improve upon bounds from previous direct searches by up to four orders of magnitude in a frequency band from 10 to 180 Hz.
我们报告了一项利用激光干涉引力波天文台（LIGO）第三次观测运行数据对标量场暗物质进行的直接搜索。我们分析了可能由标量场暗物质引起的干涉仪分束器和臂测试质量块的尺寸振荡耦合。使用新的高效搜索方法来最大化对此类振荡信号的灵敏度，我们设定了标量场暗物质耦合常数随其质量变化的新上限，在10至180赫兹频段内，相比之前直接搜索的界限提高了多达四个数量级。
