Measurement of inclusive lepton cross sections with the ATLAS detector

We present measurements of the inclusive differential cross-sections of electron and muon production in proton-proton collisions at a centre-of-mass energy of sqrt(s) = 7 TeV. From a data sample of 1.4 pb-1 we present electron and muon cross-sections as a function of transverse momentum, p_T, in the...

description We present measurements of the inclusive differential cross-sections of electron and muon production in proton-proton collisions at a centre-of-mass energy of sqrt(s) = 7 TeV. From a data sample of 1.4 pb-1 we present electron and muon cross-sections as a function of transverse momentum, p_T, in the range 7 <p_T< 26 GeV and within pseudorapidity |eta| < 2.0. In addition, muons are studied in an extended kinematic range of 4 <pT< 100 GeV and |eta| < 2.5. The measurements are found to be in good agreement with theoretical predictions for heavy flavour production and are sensitive for the first time to the Next to Leading Log contribution to the heavy flavour production in pp collisions.
