This Letter presents measurements of the differential cross-sections for inclusive electron and muonproduction in proton–proton collisions at a centre-of-mass energy of√s = 7 TeV, using data collectedby the ATLAS detector at the LHC. The muon cross-section is measured as a function of pT in the range4 < pT < 100 GeV and within pseudorapidity |η| < 2.5. In addition the electron and muon cross-sectionsare measured in the range 7 < pT < 26 GeV and within |η| < 2.0, excluding 1.37 < |η| < 1.52. Integratedluminosities of 1.3 pb−1and 1.4 pb−1are used for the electron and muon measurements, respectively.After subtraction of the W/Z/γ∗contribution, the differential cross-sections are found to be in goodagreement with theoretical predictions for heavy-ﬂavour production obtained from Fixed Order NLOcalculations with NLL high-pT resummation, and to be sensitive to the effects of NLL resummation.
