暗物质存在于我们的宇宙中，但它的性质仍然是神秘的。激光干涉引力波天文台（LIGO）的非凡灵敏度可能能够解开这个谜团。一个很好的暗物质候选者是超轻暗光子。由于它与普通物质的相互作用，它会引起LIGO反射镜的位移，从而产生可观察到的信号。在一项连接引力波科学和粒子物理学的研究中，我们使用LIGO第一次（O 1）数据运行的数据进行直接暗物质搜索，而不是通过产生引力波间接搜索暗物质。我们证明了在m（A）附近的U（1）（B）暗光子暗物质质量带中，在类似于4 × 10（-13）eV的平方耦合上实现的灵敏度类似于4 × 10（-45）。在未来几年里，LIGO和其他引力波探测器在不断增长的全球网络中继续采集数据，预计搜索灵敏度将大幅提高。
Dark matter exists in our Universe, but its nature remains mysterious. The remarkable sensitivity of the Laser Interferometer Gravitational-Wave Observatory (LIGO) may be able to solve this mystery. A good dark matter candidate is the ultralight dark photon. Because of its interaction with ordinary matter, it induces displacements on LIGO mirrors that can lead to an observable signal. In a study that bridges gravitational wave science and particle physics, we perform a direct dark matter search using data from LIGO's first (O1) data run, as opposed to an indirect search for dark matter via its production of gravitational waves. We demonstrate an achieved sensitivity on squared coupling as similar to 4x 10(-45), in a U(1)(B) dark photon dark matter mass band around m(A) similar to 4 x 10(-13) eV. Substantially improved search sensitivity is expected during the coming years of continued data taking by LIGO and other gravitational wave detectors in a growing global network.
