Don't be a WIMP - new ideas for light dark matter — •Felix Kahlhöfer — Institute for Theoretical Particle Physics and Cosmology (TTK), RWTH Aachen University, D-52056 Aachen, Germany

In spite of the overwhelming evidence for the existence of dark matter, its properties remain elusive. I will review the global effort to search for dark matter and discuss the implications of the present absence of new signals. A consistent combination of all available information mounts pressure on the idea of Weakly Interacting Massive Particles, which may point to a production mechanism in the Early Universe different from thermal freeze-out. I will review a number of attractive alternatives and discuss their theoretical and experimental implications.
