Measurements of the electron and muon inclusive cross-sections in proton–proton collisions at $\sqrt{s}$ = 7 TeV with the ATLAS detector

Abstract

We present the 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 ∼1.4 pb^− 1 of data collected by the ATLAS detector at the Large Hadron Collider. The muon cross-section is measured as a function of muon transverse momentum 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. 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.
