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

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 p T in the range 4 < p T < 100 GeV and within pseudorapidity | η | < 2 . 5. In addition the electron and muon cross-sections are measured in the range 7 < p T < 26 GeV and within | η | < 2 . 0, excluding 1 . 37 < | η | < 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 / 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.
