摘要:

我们提出的第一个限制非弹性电子散射暗物质和暗光子吸收使用的原型SuperCDMS探测器具有0.1电子空穴对的电荷分辨率(CDMS HVeV,0.93克CDMS HV设备)。这些电子反冲极限显著改善了对质量低至1 MeV/ $\mathrm{c^2}$的暗物质粒子的实验限制。我们证明了与其他领先的方法竞争,但使用显着更少的曝光(0.49克天)的暗光子的灵敏度。这些结果表明,声子介导的半导体探测器是敏感的单电子激发的科学潜力。

英文摘要:

We present the first limits on inelastic electron-scattering dark matter and dark photon absorption using a prototype SuperCDMS detector having a charge resolution of 0.1 electron-hole pairs (CDMS HVeV, a 0.93 gram CDMS HV device). These electron-recoil limits significantly improve experimental constraints on dark matter particles with masses as low as 1 MeV/$\mathrm{c^2}$. We demonstrate a sensitivity to dark photons competitive with other leading approaches but using substantially less exposure (0.49 gram days). These results demonstrate the scientific potential of phonon-mediated semiconductor detectors that are sensitive to single electronic excitations.
