The differential cross section for the process Z/√ → ℓℓ (ℓ = e, μ) as a function
of dilepton invariant mass is measured in pp collisions at ps = 7TeV at the LHC using
the ATLAS detector. The measurement is performed in the e and μ channels for invariant
masses between 26 GeV and 66 GeV using an integrated luminosity of 1.6 fb−1 collected in 2011 and these measurements are combined. The analysis is extended to invariant masses as low as 12 GeV in the muon channel using 35 pb−1 of data collected in 2010. The cross sections are determined within fiducial acceptance regions and corrections to extrapolate the measurements to the full kinematic range are provided. Next-to-next-to-leading-order QCD predictions provide a significantly better description of the results than next-to-leadingorder QCD calculations, unless the latter are matched to a parton shower calculation.
