Abstract / Description:Whereas first hints for the existence of Dark Matter have been observed by the Swiss astronomer Zwicky already in the thirties of the last century, it turned out only during the last years, that the universe in fact is dominated by particles whose nature is almost unknown and that have never been observed directly.
As the existence of these particles meanwhile is postulated not only by astronomy, but also cosmology and theoretical particle physics, there is big effort to detect them in a laboratory experiment and to determine their physical properties. However, as the interaction rate between Dark Matter particles and ordinary matter is extremely low, detectors have to be extremely sensitive. Low temperature detectors have been developed for more than one decade now and in the mean time reached the highest sensitivity for direct Dark Matter detection.
In this article, we give a short overview of observational results that suggest the existence of Dark Matter particles and of what physicists have learned so far about their properties. The main focus is on the experimental challenges and effort for their direct detection.
