Dark matter in direct, indirect and collider experiments
Neil Weiner of New York University explains how the search for dark matter is going, and why he is confident we will find it, or at least know what we are looking for, in the near future. The properties of dark matter may be influenced by new forces that effect how dark matter interacts with itself and with ordinary matter. Such forces can lead to new signals in direct or indirect dark matter searches, and might explain some of the anomalous results already reported by such searches. Interacting dark matter may also explain the mysterious properties of dwarf galaxies.
