Measurements of the electron and muon inclusive cross-sections in proton–proton collisions at √s = 7 TeV with the ATLAS detector

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 = 7 TeV, using data collected by the ATLAS detector at the LHC. The muon cross-section is measured as a function of pτ in the range 4 < pτ < 100 GeV and within pseudorapidity |η| < 2.5. In addition the electron and muon cross-sections are measured in the range 7 < pτ < 26 GeV and within |η| < 2.0, ex⁻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-pτ resummation, and to be sensitive to the effects of NLL resummation.
