This paper describes precision measurements of the transverse momentum p_mathrm {T}^{ell ell }p T ℓℓ (ell =e,muℓ=e,μ) and of the angular variable phi ^{*}_{eta }ϕ η∗ distributions of Drell–Yan lepton pairs in a mass range of 66–116 GeV. The analysis uses data from 36.1 fb^{-1} −1 of proton–proton collisions at a centre-of-mass energy of sqrt{s}=13, s=13TeV collected by the ATLAS experiment at the LHC in 2015 and 2016. Measurements in electron-pair and muon-pair final states are performed in the same fiducial volumes, corrected for detector effects, and combined. Compared to previous measurements in proton–proton collisions at sqrt{s}=7 s=7 and 8,8TeV, these new measurements probe perturbative QCD at a higher centre-of-mass energy with a different composition of initial states.
