E-Wimps

Abstract

Extremely weakly interacting massive particles (E-WIMPs) are intriguing candidates for cold dark matter in the Universe. We review two well motivated E-WIMPs, an axino and a gravitino, and point out their cosmological and phenomenological similarities and differences, the latter of which may allow one to distinguishing them in LHC searches for supersymmetry.
