我们使用$ 10.6 $ $ \ MATHRM {g} $ si Athermal Phonon探测器的基线能量分辨率为$σ_e= 3.86 \ pm 0.04 $ $(\ MATHRM {stat。}。 $ \ mathrm {ev} $。该排除分析设置了一个最严格的暗物质 - 核子散射横截面极限,这是一个低温检测器对暗物质粒子质量从$ 93 $到$ 140 $ $ \ $ \ mathrm {Mev}/c^2 $,原始暴露量为$ 9.9 $ $ $ $ $ $ \ nathrm {g} \ cdot and and-and and-这项工作说明了使用Athermal Phonon传感器的探测器的科学潜力,并通过EV规模的能量分辨率解决了未来的暗物质搜索。
We present limits on spin-independent dark matter-nucleon interactions using a $10.6$ $\mathrm{g}$ Si athermal phonon detector with a baseline energy resolution of $σ_E=3.86 \pm 0.04$ $(\mathrm{stat.})^{+0.19}_{-0.00}$ $(\mathrm{syst.})$ $\mathrm{eV}$. This exclusion analysis sets the most stringent dark matter-nucleon scattering cross-section limits achieved by a cryogenic detector for dark matter particle masses from $93$ to $140$ $\mathrm{MeV}/c^2$, with a raw exposure of $9.9$ $\mathrm{g}\cdot\mathrm{d}$ acquired at an above-ground facility. This work illustrates the scientific potential of detectors with athermal phonon sensors with eV-scale energy resolution for future dark matter searches.
