Abstract

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⁺e⁻ channel is measured with the ATLAS detector as a function of the invariant mass, m_ee, in the range 116 <m_ee <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.
