Abstract :
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 CaWO4 and 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.
