CERN-LHC. Based on an integrated luminosity of 4.9 /fb, the differential cross-section in the Z/gamma* to e+e- channel is measured with the ATLAS detector as a function of the invariant mass, Mee, in the range 116 < Mee < 1500 GeV, for a fiducial region in which both the electron and the positron have transverse momentum pT > 25 GeV and absolute pseudorapidity |eta| < 2.5.
Note that based on the update of the ATLAS Luminosity measurement (Eur.Phys.J. C73 (2013) 2518) the measured cross-sections given here and in the paper need to be scaled up by 1.4%. The luminosity uncertainty stays at the previous value of 1.8%.
