Query: Search for long-lived particles decaying to leptons with large impact
  parameter in proton-proton collisions at $\sqrt{s}$ = 13 TeV   A search for new long-lived particles decaying to leptons using proton-proton
collision data produced by the CERN LHC at $\sqrt{s}$ = 13 TeV is presented.
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
10 cm 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 (e$\mu$ and
$\mu\mu$ channels). The search is designed to be sensitive to a wide range of
models with displaced e$\mu$, ee, and $\mu\mu$ 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.
