New Signatures of WIMPless Dark Matter

We consider new signatures of WIMPless dark matter, particularly those which can be used to test models with low dark matter mass. We focus on detection prospects at hadron colliders through the production of new heavy QCD-coupled particles, which decay to WIMPless dark matter plus jets. We find that the Tevatron can probe a significant fraction of the low mass parameter space with data already taken, and the LHC will have even better detection prospects with its first physics run.
