BEYOND WIMPS • Does the WIMP paradigm imply WIMPs? • The WIMP miracle seemingly implies that dark matter is – Weakly-interacting – Cold – Collisionless Are all WIMP miracle-motivated candidates like this? • No! Recently, have seen many new classes of candidates. Some preserve the motivations of the WIMP paradigm, but have qualitatively different properties 23 Mar 11 Feng 29
