Measurement of the high-mass Drell–Yan differential cross-section in pp collisions at √s=7TeV with the ATLAS detector

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...
