Abstract: Many extensions of the Standard Model of Particle Physics that address open issues, such as dark matter and baryogenesis, call for long-lived particles that decay at macroscopic distance from the interaction point, which often result in unconventional signatures in the detector. These can easily escape the scrutiny of the existing prompt searches at the LHC. Therefore, the vast class of interesting long-lived phenomena presents rich discovery opportunities for the (HL-)LHC. In this talk I will provide an overview of recent searches for exotic physics at the CMS experiment, with particular focus on the broad spectrum of final state signatures of long-lived particles, including displaced photons/leptons/jets, disappearing tracks, stopped particles, and emerging jets.
