Searches for dark matter at the LHC with the CMS experiment

Complementary to direct detection experiments, CMS has performed searches for dark matter at the LHC. In pp collisions, dark matter may be pair produced and detected in channels with a monojet, monophoton or a monolepton. In the latter, different couplings to u- and d-quarks could be studied via interference. Searches have been performed using the full 2012 dataset and are competitive to direct detection experiments. Very low low dark matter masses (Mchi lt 10 GeV) are only accessible at the LHC.
