abstract = {A search for new physics with non-resonant signals in dielectron and dimuon
 nal states in the mass range above 2TeV is presented. This is the  rst search for nonresonant
signals in dilepton  nal states at the LHC to use a background estimate from the
data. The data, corresponding to an integrated luminosity of 139 fb�����1, were recorded by the
ATLAS experiment in proton-proton collisions at a center-of-mass energy of ps = 13TeV
during Run 2 of the Large Hadron Collider. The benchmark signal signature is a two-quark
and two-lepton contact interaction, which would enhance the dilepton event rate at the TeV
mass scale. To model the contribution from background processes a functional form is  t to
the dilepton invariant-mass spectra in data in a mass region below the region of interest. It
is then extrapolated to a high-mass signal region to obtain the expected background there.
No signi cant deviation from the expected background is observed in the data. Upper
limits at 95% CL on the number of events and the visible cross-section times branching
fraction for processes involving new physics are provided. Observed (expected) 95% CL
lower limits on the contact interaction energy scale reach 35.8 (37.6)TeV.},
