我们报告的结果，第一次地下暗物质搜索与光与热歧视。它已在Canfranc地下实验室的框架下，罕见的对象SEARCH与测辐射热计Underwear D（ROSEBUD）合作与双测辐射热计组成的54克结晶CaWO4和薄锗（0.26克）的光探测。它的能力，以区分核电子反冲已被证明和应用于推导弱相互作用大质量粒子（WIMP）暗物质候选者的限制。
We report on the results of the first underground dark matter search with light versus heat discrimination. It has been performed at the Canfranc Underground Laboratory in the frame of the Rare Objects SEarch with Bolometers UndergrounD (ROSEBUD) Collaboration with a double bolometer consisting of a 54 g scintillating CaWO4and a thin Ge (0.26 g) for light detection. Its capability to distinguish nuclear against electron recoils has been proved and applied to derive limits for weakly interacting massive particle (WIMP) dark matter candidates.
