Search for Dark Matter — •Christian Weinheimer — Institut für Kernphysik, Universität Münster

Cosmology and astrophysics give strong evidence by different observables for the existance of 6 times more matter in the universe than baryonic matter. This Dark Matter is believed to be composed of a new type of particle. They are hunted in 3 different ways: By direct search experiments in underground labs looking for the scattering of Dark Matter particles off nuclei or atomic electrons, by looking for annihilation or decay products of Dark Matter particles in gamma or neutrino telescopes or by looking for their production in high energy collisions, e.g. at the Large Hadron Collider at CERN. No compelling evidence has been found so far.

Still, massive weakly interacting particles (WIMPs) are ideal dark matter candidates which would be created naturally at the right amount in the early universe. Currently underground liquid noble gas detectors, like XENON1T, and cryobolometers, like CRESST, are aiming to investigate the allowed parameter space down to the ``neutrino floor'', an ultimate background defined by coherent neutrino scattering. New approaches are aiming for axions and axion-like particles or sterile neutrinos, other candidates for dark matter.

In this talk the recent status of direct and indirect dark matter search is presented.
