Measurement of the muon inclusive cross section in pp collisions at $\sqrt{s}$ = 7 TeV with the ATLAS detector

The measurement of the muon inclusive di?fferential cross section dsigma/dpT in pp collisions at sqrt(s)=7 TeV with the ATLAS detector is presented. The analysis is performed in the pseudorapidity interval |eta|< 2.5 for muon of transverse momentum 4 < pT < 100 GeV and with an integrated luminosity of 1.4 pb-1. The result is compared with the next-to-leading order with next-to-leading log high pT resummation prediction for the heavy avour production and with MC@NLO prediction for W-Z bosons production. The measurement is sensitive for the ?rst time to the next-to-leading log contribution to the heavy flavour production in hadronic interactions.
