This Letter reports a measurement of the high-mass Drell-Yan differential cross-section in proton-proton collisions at a centre-of-mass energy of 7 TeV at the LHC. Based on an integrated luminosity of 4.9fb-1, the differential cross-section in the Z/??????*?????????e+e- channel is measured with the ATLAS detector as a function of the invariant mass, mee, in the range 116<mee<1500GeV, for a fiducial region in which both the electron and the positron have transverse momentum pT>25GeV and pseudorapidity |??????|<2.5. A comparison is made to various event generators and to the predictions of perturbative QCD calculations at next-to-next-to-leading order. ?????? 2013 CERN.
