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.
