WISPy dark matter
Prof. Dr. Jörg Jäckel (Institut für Theoretische Physik, Universität Heidelberg)
Very light bosons, produced non-thermally in the early Universe are an intriguing possibility for the cold dark matter of the Universe. Particularly interesting candidates are axions, axion-like particles and hidden photons. This talk will discuss the current status of such light dark matter with a particular emphasis towards opportunities for its detection. We also venture to some more exotic candidates and motivations.
