Searches for Physics beyond the Standard Model at the LHC

The unprecedented center-of-mass energies available at the Large Hadron Collider provide an excellent opportunity to search for physics beyond the Standard Model. The focus of the talk will be on signatures related to Dark Matter, Black Holes, Extra Dimensions and Grand Unified Theories. Selected recent results from the ATLAS and CMS experiments will be presented, using proton-proton collision data with a center-of-mass energy of 8 TeV and an integrated luminosity of 20/fb.
