Description

CRESST-II is a direct dark matter search using cryogenic detectors based on calcium tungstate. Due to their light nuclei and low energy thresholds these detectors allow for a high sensitivity for dark-matter particles with low masses. We present data corresponding to an exposure of 52 kg-days obtained by one single detector module with a very low energy threshold of 307 eV for nuclear recoils. A blind analysis was performed on the data set resulting in a significantly improved sensitivity for dark-matter particles with masses below 3 GeV/c$^2$. Furthermore, this result extends the parameter space covered by direct dark matter searches to the sub-GeV/c$^2$ mass region.
