Searches for direct production of dark matter \\ at the LHC

This article reports on searches for new phenomena through direct production of dark matter (DM) particles at the LHC. Searches for DM made public by Summer 2015 by the CMS and ATLAS collaborations, are presented and categorized according to the event topology characteristics. The data collected in proton-proton collisions at a center-of-mass energy of 8~TeV, correspond to an integrated luminosity of 19.7~$\textrm{fb}^{-1}$ and 20.3~$\textrm{fb}^{-1}$ for CMS and ATLAS respectively. The analyses find no excess of events above the Standard Model expectations and the results are interpreted in terms of 90\% confidence limits on the DM-nucleon scattering cross-section, as a function of the DM particle mass, for both spin-dependent and spin-independent scenarios. We find that LHC collider searches provide a complementary probe of WIMPs to direct detection experiments, and give strong constraints on light DM particles.
