Measurement of inclusive lepton cross sections with the ATLAS detector

An understanding of electron and muon production in proton-proton (pp) collisions is a prerequisite for measurements and searches including these particles in the final state. Moreover, the inclusive production of these particles can be used to constrain theoretical predictions for heavy-flavour production, for which large uncertainties exist. We have measured the p$_{T}$ spectra of inclusive electrons and muons; comparisons to theoretical predictions are also reported. In particular, theoretical predictions for heavy-flavour production obtained from Fixed Order Next to Leading Order calculations with Next to Leading Log high-pT resummation (from the FONNL program) can be probed directly for the first time at the LHC.
