Abstract (data abstract)
A search for high-mass dielectron and dimuon resonances in the mass range of 250 GeV to 6 TeV is presented. The data were recorded by the ATLAS experiment in proton-proton collisions at a centre-of-mass energy of $\sqrt{s}$=13 TeV during Run 2 of the Large Hadron Collider and correspond to an integrated luminosity of 139 fb$^{-1}$. Limits are set on the fiducial cross-section times branching ratio to dielectrons and dimuons for generic resonances with a relative natural width in the range of zero to 10%. Limits on the Heavy Vector Triplet model couplings and on the masses of vector resonances are inferred.

Version 3 modifications: Added two resource files containing pseudo-code with the parametrizations for the mass resolution and background functions.
