Query: LHC results for dark matter from ATLAS and CMS   The CMS and ATLAS collaborations searched for Dark Matter (DM) particles
directly produced in pair. The searches are performed using the full LHC Run-I
dataset recorded with the CMS and ATLAS detectors in proton-proton collisions
at a center-of-mass energy of 8 TeV. Signatures considered include those
yielding energetic jets and large missing transverse momentum as well as
electroweak bosons and heavy flavour quarks plus missing transverse energy. No
deviation from SM background expectation was found and exclusion limits on DM
production cross section were set.
