abstract = {A search for $t$-channel exchange of leptoquarks (LQs) is
performed in dimuon and dielectron spectra using
proton-proton collision data collected at $\sqrt{s}$ = 13
TeV with the CMS detector at the CERN LHC. The data
correspond to an integrated luminosity of 138 fb$^{-1}$.
Eight scenarios are considered, in which scalar or vector
LQs couple up or down quarks to muons or electrons, for
dilepton invariant masses above 500 GeV. The LQ masses are
probed up to 5 TeV, beyond a regime probed by previous
pair-production and single-production searches. The
differential distributions of dilepton events are fit to
templates that model the nonresonant LQ exchange and various
standard model background processes. Limits are set on
LQ-fermion coupling strengths for scalar and vector LQ
masses in the 1-5 TeV range at 95\% confidence level,
establishing stringent limits on first- and
second-generation LQs.},
