Searches for dark matter candidates at the LHC

Several observation in astrophysics provide the strong evidence for dark matter in the universe. The current value of the dark matter density is already determined precisely, however its identify is completely unknown. Several new physics beyond the Standard Model predict an excellent candidate of dark matter candidates. In this talk, we focus on one of promising theories, Supersymmetry and discuss on the discovery potential and how to identify the dark matter at the LHC.
