Searches For Long-Lived Particles and Other Exotica at the LHC

The ATLAS and CMS experiments at the LHC are currently searching for a long-lived particles and other exotica with a wide range of signatures. This talk will summarize recent results from both experiments that rely on novel and challenging signatures to probe numerous models of physics beyond the Standard Model, including supersymmetry, twin Higgs models, and inelastic dark matter models.
