Many theories beyond the Standard Model predict new particles with macroscopic lifetimes, giving rise to striking displaced signatures at collider experiments. These long-lived particles (LLPs) often evade standard reconstruction and triggering techniques, motivating dedicated strategies and innovative use of detector capabilities to enhance search sensitivity. In this seminar, I present results from searches for LLPs using CMS data from Run 2 and the ongoing Run 3 of the LHC, including a novel approach based on the muon detector shower signature. I conclude with prospects for the High-Luminosity LHC, where upcoming detector and trigger upgrades will enable next-generation LLP searches.
