Events are selected with two leptons (an electron and a muon, two electrons, or two muons) that both have transverse impact parameter values between 0.01 and 10cm and are not required to form a common vertex. Data used for the analysis were collected with the CMS detector in 2016, 2017, and 2018, and correspond to an integrated luminosity of 118 (113)fb-1 in the ee channel (eμ and μ μ channels). The search is designed to be sensitive to a wide range of models with displaced eμ, ee, and μ μ final states. The results constrain several well-motivated models involving new long-lived particles that decay to displaced leptons. For some areas of the available phase space, these are the most stringent constraints to date. © 2022, The Author(s).Springer Nature2022Articlehttps://rdlopen.rawdatalibrary.net/r/ebyu/12778https://doi.org/10.1140/epjc/s10052-022-10027-31434-6044enEuropean Physical Journal Cinfo:eu-repo/semantics/openAccessinfo:eu-repo/semantics/articlehttps://ebyu-rdlopen.rawdatalibrary.net/tr/items/ebyu/12778
