Speaker: Małgorzata Kazana (NCBJ) Title: “Searches for long-lived particles with the CMS detector” Abstract: Models beyond the SM predict new particles with a wide range of lifetimes. These particles can get a long lifetime which lead to unconventional signatures in the detector with respect to particles from prompt decays, often requiring customised techniques to trigger and identify them. The CMS experiment puts a growing effort to expand the reach for long-lived signals. During the talk, selected studies with the full LHC Run2 data on long-lived particles will be shown.
