Searches for long-lived particles and non-conventional signatures in CMS

Many extensions of the Standard Model of Particle Physics that address open issues, such as dark matter and matter-antimatter asymmetry, call for long-lived particles that decay at macroscopic distance from the interaction point, which often result in non-conventional 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 but not limited to, displaced photons/leptons/jets, disappearing tracks, stopped particles, and emerging jets.
