# WIMPs and Gravitinos

I was just wandering if a gravitino could be in the WIMP class, because they are both massive (admittedly WIMP's more so) and are both weakly interacting and predicted by R-parity. i.e Gravitinos are a sub class of WIMPs.

According to Wikipedia the answer is yes: en.wikipedia.org/wiki/Gravitino –  John Rennie Mar 12 '13 at 7:03
"admittedly WIMP's more so" In some models. They are as yet unobserved, and the masses are only known in a very general sense of "Well, if we makes this small set of very reasonable assumptions we can estimate the mass range to expect." –  dmckee Mar 23 '13 at 14:47
