• # 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 $p_{\text{T}}$ in the range $4 &lt; p_{\text{T}} &lt; 100$ GeV and within pseudorapidity $|\eta| &lt; 2.5$. In addition, the electron and muon cross-sections are measured in the range $7 &lt; p_{\text{T}} &lt; 26$ GeV and within $|\eta| &lt; 2.0$, excluding $1.37 &lt; |\eta| &lt; 1.52$. After subtraction of the$W/Z/\gamma^{*}$ 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-$p_{\text{T}}$ resummation, and to be sensitive to the effects of NLL resummation.
