用大型金属镜探测隐藏光子暗物质
Hidden Photon Dark Matter Search with a Large Metallic Mirror
摘要：
如果暗物质是由隐藏扇区的光子与可见扇区的光子动力学混合组成的，那么暗物质就有一个微小的振荡电场分量。它的存在会导致少量的可见辐射从导电表面发出，光子频率近似由隐藏光子的质量给出。在这里，我们报告的实验努力，最近已经开始寻找这种隐藏的光子暗物质在（分）电子伏特制度与原型镜的俄歇荧光探测器在卡尔斯鲁厄理工学院。
英文摘要：
If Dark Matter is composed of hidden-sector photons that kinetically mix with photons of the visible sector, then Dark Matter has a tiny oscillating electric field component. Its presence would lead to a small amount of visible radiation being emitted from a conducting surface, with the photon frequency given approximately by the mass of the hidden photon. Here, we report on experimental efforts that have started recently to search for such hidden photon Dark Matter in the (sub-)eV regime with a prototype mirror for the Auger fluorescence detector at the Karlsruhe Institute for Technology.
