光暗物质在引力波探测器中的散射

Light Dark Matter Scattering in Gravitational Wave Detectors

Chun-Hao Lee, Chrisna Setyo Nugroho, Martin Spinrath

摘要:

我们提出了在引力波探测器中发现暗物质散射的前景。这项工作的重点是轻,粒子暗物质的质量低于1 GeV/c $^{2}$。我们研究了一个潜在的信号如何与热噪声和量子噪声等典型背景进行比较,首先在一个简单的玩具模型中,然后使用KAGRA作为一个现实的例子。这表明,对于一个发现,更轻和更冷的镜子将是必要的。我们还对天基实验和未来的原子干涉仪作了一些简要的评论。

英文摘要:

We present prospects for discovering dark matter scattering in gravitational wave detectors. The focus of this work is on light, particle dark matter with masses below 1 GeV/c$^{2}$. We investigate how a potential signal compares to typical backgrounds like thermal and quantum noise, first in a simple toy model and then using KAGRA as a realistic example. That shows that for a discovery much lighter and cooler mirrors would be needed. We also give some brief comments on space-based experiments and future atomic interferometers.
