标题： Wideband Direct Detection Constraints on Hidden Photon Dark Matter with the QUALIPHIDE Experiment

摘要： 我们报告了使用低温发射器-接收器-放大器光谱设置对质量在20-30微电子伏特范围内的隐藏光子暗物质存在的方向检测约束，该设置设计为QUALIPHIDE（量子限制的暗场光子实验）的第一代。 金属碟将隐藏光子的动能混合转换为光子，这些光子被耦合到C波段动能电感行波参量放大器，实现了接近量子极限的噪声性能。 我们展示了对大部分该区域隐藏光子质量的动能混合参数"chi"的首次探测，其值略高于10^-12。 这些结果不仅代表了对新的暗物质参数空间的严格约束，而且也是首次在天体粒子应用中展示宽带量子极限放大技术。 显示英文摘要

摘要： We report direction detection constraints on the presence of hidden photon dark matter with masses between 20-30 ueV using a cryogenic emitter-receiver-amplifier spectroscopy setup designed as the first iteration of QUALIPHIDE (QUantum LImited PHotons In the Dark Experiment). A metallic dish sources conversion photons from hidden photon kinetic mixing onto a horn antenna which is coupled to a C-band kinetic inductance traveling wave parametric amplifier, providing for near quantum-limited noise performance. We demonstrate a first probing of the kinetic mixing parameter "chi" to just above 10^-12 for the majority of hidden photon masses in this region. These results not only represent stringent constraints on new dark matter parameter space but are also the first demonstrated use of wideband quantum-limited amplification for astroparticle applications
