Abstract:
The largest fraction of matter in the Universe is so called Dark Matter. There is strong observational evidence that its nature is connected to physics beyond the standard model of particle physics. The sensitivity to search for Dark Matter particles via elastic scattering on nuclei has increased dramatically over the last years. The CRESST experiment is using scintillating low temperature calorimeters. By measuring simultaneously heat and scintillation signals, the type of the interacting particle can be recognized. This technique is very promising for future projects, since it allows multi-target detectors. CRESST recently has published results from about two years of datataking at the Gran Sasso Underground laboratory. So far, not all signals can be explained by known background sources.
