  This letter presents measurements of the differential cross-sections for
inclusive electron and muon production in proton-proton collisions at a
centre-of-mass energy of sqrt(s) = 7 TeV, using data collected by the ATLAS
detector at the LHC. The muon cross-section is measured as a function of pT in
the range 4 < pT < 100 GeV and within pseudorapidity |eta| < 2.5. In addition
the electron and muon cross-sections are measured in the range 7 < pT < 26 GeV
and within |eta| <2.0, excluding 1.37<|eta|<1.52. Integrated luminosities of
1.3 pb-1 and 1.4 pb-1 are used for the electron and muon measurements,
respectively. After subtraction of the W/Z/gamma* contribution, the
differential cross-sections are found to be in good agreement with theoretical
predictions for heavy-flavour production obtained from Fixed Order NLO
calculations with NLL high-pT resummation, and to be sensitive to the effects
of NLL resummation.
