摘要
Article history: Received 17 May 2013 Received in revised form 23 July 2013 Accepted 24 July 2013 Available online 1 August 2013 Editor: W.-D. Schlatter 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 4.9 fb-1, the differential cross-section in the Z/γ ∗ → e+echannel 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 p T > 25 GeV and pseudorapidity |η| < 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. Published by Elsevier B.V. All rights reserved.
