Abstract

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 s=7TeV, using data collected by the ATLAS detector at the LHC. The muon cross-section is measured as a function of p_T in the range 4<p_T<100GeV and within pseudorapidity |η|<2.5. In addition the electron and muon cross-sections are measured in the range 7<p_T<26GeV and within |η|<2.0, excluding 1.37<|η|<1.52. Integrated luminosities of 1.3pb^-1 and 1.4pb^-1 are 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 good agreement with theoretical predictions for heavy-flavour production obtained from Fixed Order NLO calculations with NLL high-p_T resummation, and to be sensitive to the effects of NLL resummation.
